20 Best Wireless Modem For Xfinity (2023 Updated)

Can’t knock the speed on this thing; detected no measurable loses compared to my aging Netgear modem. In other words. I get all the speed I am paying for. But the problem with this modem (and I suspect many others now.

) is that if you have Comcast/Xfinity, they will provision this modem and download their boot module into it, which then locks you out of the ‘Web Manager’ internal status web page of the device. I thought something was fishy when I couldn’t log into through my router arrangement @ 192.

168. 100. 1 – so it prompted me to connect my laptop directly to it (as Arris recommends anyway). What I got was a login page that wouldn’t allow access because the user name or password had been altered – meaning – the defaults were modified.

It’s important to be able to see the internal logs and the signal/bonding stats from time to time to see if your ISP is having outside infrastructure problems. With Comcast shutting things down, they are basically altering the device you paid for with no notification.

Not cool. Not cool at all. The other problem that prompted me to score this device low is the mobile app Arris prompts you to use to set up and configure your device. Don’t waste your time with that on this particular device.

It offers nothing of value beyond the information you already have access to on the bottom product label or the quick start card. It’s these types of not-even mediocre attempts to promote ‘mobile app’ benefits that are pretty much deceitful – and that would otherwise prompt me to give this modem 0 stars if the BB review section allowed it.

Coupled with the no-go Web Manager lock-out. I can’t recommend this product whatsoever. Giving this modem ‘average’ scores on performance and connection quality only because I’ve used it for such a short period of time.

If you sort the reviews by lowest score first, you will see that the S33 also has medium to long term reliability issues that the typical social media agents of Arris will reply to in recognizably unsupported ways.

Take those for what they are worth!.

The ARRIS S33 is a better investment than the pricier Netgear counterpart. It’s the most compact Multi-Gig modem, measuring just ‎5. 14 x 1. 8 x 4. 74 in and weighing less than a pound. Like all DOCSIS 3.

1 modems, the SURFboard S33 can function as a top-tier DOCSIS 3. 0 modem. You should use it only when you have a download speed of around 400Mbps or faster. That’s because certain low-speed cable plans require a DOCSIS 3.

0 modem to work. The S33 is designed to work with a Wi-Fi 6 router, preferable one with a Multi-Gig WAN port. If you have a Wi-Fi 5 router, you will need to upgrade it or stick with a DOCSIS 3. 0 modem.

The S33 comes with a single large LED light on the front. This light changes its color to show the modem’s conditions. It has three colors: Amber – modem is off; Green means the modem is on and Flashing – firmware update is in process.

Blue is only available in solid and means the modem is working well in DOCSIS 3. 1 mode. This all depends on the internet plan you have. Make sure, though, that you have a Wi-Fi router that has a matching WAN speed.

I’ve had this modem for 4 months now, and I’ve been very impressed. I choose the Arris S33 over the Motorola MB8611 mostly because it was on sale at the time for less, plus I had BestBuy rewards credit to put toward it.

The modem itself has been a bit of an improvement over my Xfinity XB7. The XB7 is also made by Arris, but uses an Intel chipset, the S33 uses a newer Broadcom chipset that I feels performs better. With the XB7, even though I have 1.

2 Gb speeds, at most I would only hit approximately 900 Mb with downloads. The S33 hits at 1. 1 Gb on the same Speedtest. net test using the same server. I can confirm that this modem runs pretty hot.

Using a digital thermometer, I was reading 134 degrees F at the top vents, compared to 107 degrees coming out of the my ASUS RT-AX86U router running 30 devices. My solution was to get a 120mm USB fan and place it underneath the modem, and that cooled things down significantly.

Finally decided to upgrade my internet speed and i needed to replace the Arris cable modem that had provided over 8 years of faithful service. Upon the recommendation of the Spectrum cable tech, i purchased a Netgear cable modem.

First time using a Netgear product. I heard many good things over the years, but never felt the need to purchase any of their products since ive had no issues with Arris, Motorola, and Linksys devices.

Took Spectrum a few moments after receiving the mac address to have my new Netgear up and running. So far, no complaints. My connection is strong and steady. Im using this modem to power my Linksys Mesh network using wifi6.

At any given moment, there are at least 40+ devices with 2 tvs constantly streaming in 4k. The Netgear and Linksys are both working great. As of right now, i would definitely recommend this model. If you’re a Spectrum customer who doesn’t want to pay rental fees for their cable modem (which is actually pretty good), make things easier on yourself and buy a Netgear.

It is highly recommended by their repair techs and customer service reps. Now if this modem dies in the next few days, weeks, or months, i will make a follow-up post detailing what happened.

I wanted a Modem-Router Combo with the latest DOCSIS 3. 1 and Wi-Fi 6 technology. The NIGHTHAWK CAX80 met the technical requirements. Installing the CAX80 wasn’t as easy as advertised. I could not ‘self activate’ thru the Web.

The Nighthawk Smartphone App can be used to setup WiFi, but does not setup Modem. My cable company is Spectrum. I’ve had my internet account with them (including their predecessor Time-Warner and RoadRunner) for more than 20 years.

Their customer service is excellent–once you get a live person. They performed diagnostics and said the modem was working. However, I could not connect to the internet. They gave me a direct number to Netgear, and I called for assistance.

Within minutes my modem-router was working perfectly. They are remarkably competent. The Wi-Fi signal is stronger and more constant without fluctuation than my older modem-router. No pauses or buffering when watching streaming video movies.

The Netgear advertising is accurate and reliable. So is the performance. I am well pleased and highly recommend this router.

This is a well built product. Its body made from a very light and yet very durable material. I love the gray color which also enhance its sleek look design. What I like most about its design is that there are many ventilation holes on both side which would allow hot heat to easily escape.

Modem set up is very simple and the GUI is also very user friendly, I went through it like the breeze without encountering any glitch. It is a Multi-Gigabit Cable Modem with 2. 5 GB Ethernet. It is compatible with Xfinity, Cox and Spectrum DOCSIS 3.

1. If you already have a gigabit internet plan and your ISP allows you to use your own modem, the Motorola MB8600 is the best of the DOCSIS 3. 1 modems that are widely available right now because of its great low price and its two-year warranty.

You’ll need a DOCSIS 3. 1 modem to guarantee gigabit speeds from most cable ISPs, and the MB8611 is also backward compatible with gigabit internet on networks that still use the DOCSIS 3. 0 standard.

Don’t get a gigabit modem unless you already have gigabit service. I am replacing a working Netgear – Orbi Tri-Band AC2200 Mesh WiFi System with 32 x 8 DOCSIS 3. 0 Cable Modem built-in due to the modem as contributing to the sometime unstable/bad latency, whether I was on a video calls, gaming, web browsing or whatever my internet connection would drop on randomly but now with this product my internet is much faster and staying at my internet plan allowed max most of the time which is at around 600mb/s, it is not a super fast internet speeds plan but O can definitely tell the difference with this modem! I am highly recommend this model to anyone especially those that has gig+ service.

I switched from a cable modem/router provided by my internet company to this Motorola DOCSIS 3. 1 Cable Modem and things are going well so far. Do be advised this model does not have a built-in router and one must be purchased separately for the rest of your home network to work.

Otherwise it will work fine and brilliantly with just a single device with an Ethernet port with no other equipment needed. I do not own an internet phone either, but be advised this modem also has no jack for that.

The enclosed quick start guide gave clear instructions and set up was fairly quick and simple. I am using mine with Spectrum internet service and the compatibility is just fine. As a matter of fact as soon as I plugged my computer into the modem it recognized and took me straight to my Spectrum’s account page to activated it without me having to search.

I was disappointed that the enclosed ethernet cord was very short. I have to place the modem closer to my device or buy a longer cord myself. I suppose I am what is considered a light internet user. I do not really notice significantly increased/improved speeds save the occasional YouTube or Netflix video no longer has degraded picture quality or loading issues like sometimes happened with my old modem.

Webpages on my personal computer also seem to load smoother. I would have to reboot my old modem at least once every few says or so; doesn’t seem to be the case with this Motorola one. I am also excited that if I do upgrade my internet devices sometime in the future I already have this modem which is capable of gigabit speeds.

This capability of providing even faster speeds as they become available in the future means this modem is a longer term investment for me.

I have 1 Gig service provided by a cable company. I have also chosen to own my modem instead of renting one from the cable company. My previous modem was also DOCSIS 3. 1 compliant, but was made by a different manufacturer.

The old modem would look like it was connected, but would lose access to the Internet. After I replaced the old modem with this one, that issue no longer happens. Based on network speed tests done just before I swapped out modems and just after, this modem appears to support speeds about 10% faster than the old modem.

Installation was easy, but did require that I chat with a technical support agent at the cable company. After I provided the MAC address and serial number of my modem, it took less than a minute for the agent to configure my connection and for my modem to connect to the Internet.

Overall, I am glad that I purchased this modem and would recommend it to anyone with 1 Gig service.

Works great! Pairing this with a Netgear Orbi RBR50 mesh system, with Comcast 600Mbps internet. Upon using the Netgear app to test my speeds I once got a 617 down/7 up. Testing with Speed Test I got a similar number.

Setup was simple to get rid of the $15 rental fee. I just unplugged the XF modem/router, plugged in the Arris via LAN to my laptop, and when trying to connect via Firefox it detected the new modem and started the setup.

After about 15 min it detected the phone line of service and I was online! Easy! Didn’t even need to call their customer service*** ***Do not use the XF app to on Android or iOS. I can’t recommend it.

It’s ability to set up my modem required very specific criteria: first, I needed to have a a modem and router setup prior to changing the old modem for the new one. Then, without disconnecting the router, I would need to switch out the XF modem with the new one then try connecting to the network again.

The app would then work, saying I would need to set up my new modem with XF. BUT, if don’t want to set it up with a new wireless system (like I did this time), there’s no way you can use the app to setup just the modem since there’s no active wireless system available to connect to.

And while I was on caller support they kept advertising the app, but not providing ample solutions to trying to connect me to the internet. Besides that, modem is working great! Save yourself $180 a year and setup a 3rd party modem.

I ordered this for my daughter moving back to an apartment near campus for the new school year. I found the power cord missing when I open the brand new box so I cannot install the cable modem. Fortunately, I live not too far from campus and brought another cable from home the next day.

I contacted Arris support and tried to get a replacement cord but they offered no help at all. So the packaging error and the poor support are the main reason for the 2 stars. I could return this to store but I cannot exchange for another one as it is only available online.

The set up is easy though once you have it connected to a router and has a device connected to it. Within 15 minutes after plugging it in, it is up and running using Xfinity. Of course, you need to have the service set up ahead of time first.

The performance is okay for the 200Mbps service we choose. It has two voice ports if you want a land line, however, there are cheaper VOIP options. This modem is pretty bulky (but very light). It doubles the size of SB8200 that I use at home.

Set up was easy IF you really follow all the directions. I watched a YouTube video for this exact model (SBV3202) which was MORE helpful than the written quick start guide. I connected the Ethernet cable directly from modem to laptop for the setup.

I had to wait 10 to 15 minutes for all the lights to become solid before completing the setup on the laptop. (If I remember correctly the Tel 1 light never came on solid until after the entire setup was complete).

I never had to call Xfinity. Remote Laptop activation worked perfectly. Once finished, Tel 1 light came on. I then Connected Ethernet cable from modem to my wireless router. Since then the modem has been functioning perfectly with no interruptions.

Happy to be saving modem rental fee. Hoping this modem functions well for a long time.

I purchase the Motorola MG8725 AX6000 cable modem router as a replacement for the Netgear CAX80-100NAS AX6000. These two devices offer similar specifications. They both tout AX6000 Wi-Fi 6 connectivity and both have gigabit (1gbps) and multi-gigabit (2.

5gbps) LAN ports. I am a Comcast Xfinity customer who recently upgraded to the Extreme Pro 1200 plan and needed to upgrade my DOCSIS 3. 0 cable modem to a DOCSIS 3. 1 cable modem to take advantage of the speed in my new plan.

While the Netgear CAX80 suffers from wired connectivity problems, the Motorola MG8725 excelled. The CAX80 would randomly drop my wired connection from its 2. 5GbE port from my PC ruining gaming experiences and downloads.

This occurs only when using the 2. 5GbE port on the cable modem and a 2. 5GbE port on my PC. However, on Netgear’s community page, many users complained of the same issue and suggest that disabling the Wi-Fi on the device would “fix” the issue; and it did.

But that is crippling my $500 experience. The MG8725 does not make me suffer from choosing fast Wi-Fi 6 or fast 2. 5GbE connections. In short, it just works, as advertised. It also costs $100 less than that of Netgear’s offering/solution.

The set up was very easy and straight forward. The device has more customization options and I feel more in control of what my device can do according to my preferences. It’s a great start to a new relationship between me and Motorola.

If you’re looking for a device that can provide a strong, fast, wireless network while also allowing you to access above 1000mbps speeds through a wired connection, give this device a chance. From my experience, you won’t be disappointed.

I bought this modem (Motorola MT7711) because it advertised download speeds over LAN and WiFi much greater than my subscribed cable speed of 400 Mbps (from Comcast). While the speed test showed that its speed on LAN (when a computer is connected to the modem using LAN cable) matched my cable’s subscribed speed on both IPv4 and IPv6, its speed on 5 GHz WiFi (at the maximum possible WiFi bandwidth of 80 MHz) is less than half (about 175 Mbps) of the subscribed speed (400 Mbps) over IPv6.

Please note that applications by default use IPv6, not IPv4, so it is very important that it gives the full speed on IPv6. Only when the speed test is forced to use IPv4 that it gives the subscribed speed (400 Mbps) on 5 GHz WiFi (when using 80 MHz WiFi bandwidth).

This behavior is very consistent and is clearly a software issue (the problem only happens on 5 GHz WiFi on IPv6, not on 5 GHz WiFi on IPv4). Also, it looks like the maximum speed that this modem can ever give on 5 GHz WiFi on IPv6 (at the maximum 80 MHz WiFi bandwidth), irrespective of how high is the cable’s subscribed speed, is about 175 Mbps.

When reached out to Motorola, their only response (besides having me do a modem reset, which made no difference) was to swap out the modem with another one (which they said could also be a refurbished one).

But that is not going to solve the problem. Since it is a software problem, it needs to be fixed in the software. Despite repeated requests, Motorola did not show any interest in doing the software fix.

Unfortunately, I discovered this critical issue after the 14 day return period; so I am stuck with it. It is so disappointing to be relegated to less than half of the subscribed speed due to this software issue with the modem, which Motorola has no interest in fixing.

The good – easy to install. Up and running in minutes. The bad – quit working 2 days after install. Spent several hours on the phone with customer service, at which point they stated I need to get my my cable provider.

it was there issue. So, I installed my old modem, and it worked. hmmm. Once I finally got them to admit it was the modem, the return process starts. You have pay to ship the modem back, and they have to receive before they will ship a replacement modem.

unless you want to pay some outrageous fee upfront for them to ship you a new one, and then you still have to pay to return the old. And your 90 day warranty still goes from the original purchase date, not when you receive the new one.

So you could be a month without a modem, and there goes 1/3 of your warranty. Thank you Amazon, as I requested to return and get a replacement, and they shipped me out a new one same day. allowing me 30 days to return the broken one.

Thats customer service. Netgear take note. Gave it a 3 because the replacement seems to be working good. Hope I don’t have to use the warranty again. after 90 days you even have to pay for tech support.

Works great, but recommend you look at other options.

I wanted to upgrade my Netgear 500V modem that I have had in place for several years. It was functioning okay but I wanted to get a newer more advanced internet voice modem they would allow me to get the higher speed that my Comcast plan provides.

From everything I read about the Arris Modem it should have taken me no more than 15 minutes to get it operating. I first tried online through my Xfinity account. After entering all the information, I got a message that about 11 minutes that the new modem would be activated.

However, in about 11 minutes I got a message that something went wrong at to try again. I tried again but with a similar result and a recommendation that I call a technician. However, since I knew that I already ha functioning older modem that the issue was trying to activate the new modem.

I then called Comcast. After 45 minutes on my cell phone, it became clear that the problem was ARRIS Surfboard. Only the power light and one other light ever came on. I then called the ARRIS technical staff as recommended in the information that came with the modem.

I was told that if Comcast could not activate it there was nothing that they could do. I then plugged in my old Netgear modem and all the lights came on. However, I had to call Comcast to reactivate my old modem.

About 15 minutes later I once again had internet and a landline phone, I then returned the ARRIS to Best Buy on the same day that I purchased it. I wasted a lot of time on trying to get a piece of equipment to function.

Maybe it was just my bad luck to get one of what may be a small percentage of Surfboard T25s that can not be activated. Very aggravating experience. I feel lucky that I have internet back thanks to my old reliable modem.

Great modem with capability for Comcast voice/phone service, however. I am nearly convinced that Comcast intentionally makes it painfully difficult to use your personally OWNED equipment. It took no less than 6 submissions of the MAC ID to Comcast BY THE COMCAST TECHNICIAN at my house before it finally came online.

The handset icon for the phone service was also lit up for a few days, however I did not have a phone to connect at the time. However a day or two before connecting a phone to the phone jack on the modem, the handset icon was no longer active.

Sure enough, when connecting my phone to the modem, there was no dial tone. After getting passed around to about 4 other support techs, nothing improved. I was told by the last tech that the issue would be corrected and the service will be online within 2-3 hours.

LOL That’s how the get you off the call. Next morning, still no service. I waited 2 days before dealing with Comcast support again, got passed around a few times again, but finally ended up with a tech that discovered that the MTA MAC ID (for the voice service) was not even populated for some reason.

Once he populated it, the modem rebooted. the phone worked, but then the internet service was offline. Fortunately he was able to re-submit the MAC ID for the internet service and finally all has been online and stable.

It really does appear as if they want you to regret attempting to use your own modem and not pay them the additional monthly rental fee for their equipment. Most people that I know would have given up and gone that route, which is only beneficial to Comcast and not their subscribers.

Love the modem and would definitely recommend! Good luck with Comcast, and don’t give up. Just keep trying and they will be the ones who eventually give up and allow your equipment to operate.

This modem has worked as advertised to this point. It was purchased for my elderly mother so that she could have telephone service. It is the same brand device that we use in our home for internet connection, and was recommended by the Best Buy staff member I spoke with.

The only issue I have with it is the price. It appears that in order to get voice capability for phone service, an expensive modem for internet service, which is unnecessary in my Mom’s case, is the only choice.

This was the least expensive modem with voice capability that I could find. It has worked perfectly so far.

Just what we needed to replace my rented Comcast/Xfinity modem. Works fine. Took a few phone calls to Xfinity to get it activated but it was well worth it. This model supports teleports if you are paying for a home phone line.

Please note that this is a modem. We already have our own router. We cannot locate a reset button. Hopefully it continues to work well and there will never be a need to unplug and plug it back in.

If you are needing a Wi-Fi router/cable modem combo that will pull actual Gigabit speeds for a few devices without much fuss, this one is perfect. That is what I required of mine when purchased a year ago and that is what I got.

If you want to to stream 4k quality TV in one room while you browse online for a new router/modem while your wife and daughter are watching TikTok on their phones and your son is using his PlayStation to test if the “unlimited data” promise from your ISP is truly unlimited, with a couple devices on Wi-Fi here and there, this modem is for you.

Mine handled all that and more for a year with little issue. Now, if I want to do some gaming with my kids… FAT CHANCE. Even with everything else disconnected, three game systems are just too much for this thing to handle and you should not expect it too.

Taking away one star because the Arris is not actually Arris, it is Commscope and the app that they push on you is complete garbage that never works and their “customer service” goes no further than “have you tried unplugging it and plugging it back in?” Beyond that and you’re on your own.

Additionally, the manufacturers warranty will have you without a modem for two weeks unless you want to shell out $100 to pay for “advanced replacement”. I recommend the replacement warranty offered by BestBuy for this device and I rarely ever say that.

We were looking for a decent cable modem & router for our apartment, so that we need not squander money paying Comcast to rent one of theirs. The reviews on this one looked good, so I pulled the trigger.

It’s a nice package, with a compact footprint which is nice. Setup via the free app software was tolerably easy. The MAC ID on this modem is not clearly identified: there are 2 of them, which differ by one character.

This caused confusion and delay when setting it up with the cable company, but once resolved ceased to be an issue. Signal strength is not as good as what you would get with a dedicated router with adjustable antennas; the thick brick walls also impede signal at the other end of the house, and was easily remedied with a $20 mesh extender.

Throughput is decent and as-advertised; note that this unit is best for households with routine data loads, rather than multiple persons streaming 8K video. For a normal user looking for a decent household modem/router, this is a good product.

I like this modem/router a LOT! It performs! I have been struggling for the past 2 years with a Spectrum supplied Technicolor modem/router. Had all kinds of glitches and irregularities with it. I couldn’t get the speeds and performance I was paying for.

Finally had enough. I couldn’t be happier with this Arris G34 modem/router combo. I have had and used many different brands of modems and routers over the years. I am very pleased with this G34. It does what it says – no if, ands or buts.

It was easy to set up. I didn’t use the App. I like to use the user interface – 192. 168. 0. 1. I had everything configured as I wanted it in a few minutes. I have a couple devices that need assigned (static) IP addresses on my network.

Doing that was a breeze with this router. The user interface in this router is probably the easiest I have ever used. I highly recommend this modem/router combo. I am now getting the speeds I should have been getting.

I am happy to know that I have the latest technology. The WiFI 6 capability and performance is phenomenal! Highly Recommend this modem/router.

I purchased this cable modem a week ago. Staples promised delivery in two days, and it was here in two days! It took about an hour to set it up and get the service provider to activate it (obviously the time consuming part was getting thru to the provider).

A word of advice, call in the morning, less phone traffic. And a word about phones, if you get your voice service thru your internet provider, you’ll need a cell phone to activate this modem (or any other modem I would imagine).

This unit replaced an eight year old Linksys N unit that was still working great, I just wanted the latest security features and figured it was time. This unit only has one cat 5 port, so you will need a router to service more than one device.

My wi-fi speed was about the same as the linksys unit, but I have my desk top hard wired to the router, and I notice about a 25% increase in speed on that. I’m a bit PO’d at Staples, though it is not their fault.

I paid $140 for this unit, and two days later it was listed for $99. 00!!! Just my luck! One thing you should know about this or any other voice modem. Contrary to what tech advisers may tell you, this unit will not work with Spectrum Voice services, you will need to use their modem for that.

It will work fine for their internet service, but you will need to keep the Spectrum modem for telephone service. Don’t spend the extra money for a voice modem (like I did!). I have had Spectrum techs tell me that Spectrum doesn’t charge rent for the modem just for voice service, but the jury is still out on that.

we’ll see!.

I connected my laptop directly to my new CM500V after installation; BOOM! It immediately activated through my ISP’s web activation page! NO calls to my ISP! (That alone is worth it’s weight in gold!) Then I connected my Netgear wireless router to my new CM500V.

I decided to change my router’s LAN IP subnet in order to have connectivity to the management page of both devices (because they both used the same subnet by default). Now my new CM500V is providing fast internet (clocked at 60 Mbps, which my ISP advertises) to my home network of 3 laptops and 2 streaming TVs.

The VOIP phone also works great; it is our home phone and is nice & clear. If you need a voice cable modem, I highly recommend the CM500V! I was surprised by the ease of installation & setup. It is excellent value for money!.

I bought this so that my 90 year old mother could have a landline phone available in her apartment after having cell phone issues for a number of days. The cell phone towers in her area were undergoing repair and she was unable to call anyone without going outside.

She needed this modem so she could hook up a phone that was already a part of her cable “package”. The modem was easy to set up, however due to the configuration of her service I had to also buy a cable splitter and an extra cable so I could hook up her phone, TV and DVD player.

not a big deal but worth knowing if you use this modem. The cost seems to be in line with similar modems but NETGEAR is a know name and I’ve always had good luck with their products. Bottom line, I had everything hooked up in less than an hour including being on the phone with the cable provider so they could detect the modem.

Very easy process.

This was probably the best purchase we made for our household within our first few months moving there. We went through three of the standard issue xfinity modem’s within the span of a couple of weeks because they ALL had the same problem.

The internet would cut out constantly when using a wired connection (???) but worked perfectly for wifi. After trying with them, we concluded their modem was the issue and decided to take the plunge and buy this one.

It was kind of on the pricey end but not bank breaking (depending on your budget), but it worked amazingly after we got it set up. Setup is easy enough if you read the directions provided. Wired connection never dipped or cut out and the wifi was perfect as usual.

As someone who both works from home and games, this purchase was certainly worth it. It’s been two years since we got it and (so far) it still works great.

I upped my xfinity subscription past my old router’s 600mbps so I bought this. So far it’s doubled my upstairs speed (5mb to 10wifi). And my phone gets 256 on WiFi while leaning on the modem. I would like to see more controls for time of use and access.

It’d be nice to be able to lockout the kids at a certain time so they’re not hiding under the covers surfing the web at 2am or to be able to cut them off from WiFi until their chores were done. I should be able to cut them off with the genie app or nighthawk app but they don’t always let me log in and the nighthawk app lacks A LOT of the genie’s functionality.

I like the one source printer share app when it works but I often have to dink with the control app on the source computer. Overall a decent device but I’d have taken it back if it wasn’t 1 of 3 products I found that had all my needed functions.

(the other two were considerably more costly and/or unavailable).

I bought this modem/router to replace Xfi. It works well. The wifi range doesn’t seem to be a wide as Xfi. And it was not an ‘open the box and set up’ experience. Everything was set up and lights on but no internet.

Had to call customer service and waited 1-1/2 hrs for help. CS Rep was not very professional, spoke over my trying to speak, was noticeable irritated. I was irritated after waiting on hold for 1-1/2hrs but still did not take it out on him.

I did mention it of course and asked if this was a typical wait time. I would really have to think twice before buying another NetGear purchase. I am looking forward to lower bills with Xfinity.

This is on sale at my favorite club store, I like and had very good luck with Netgear products. I’m changing it to the next level up because Comcast’s certification is only up to 800 Mbps. I read some of the negative reviews, especially from a so-called “electrical engineer “ who couldn’t make it do what he wanted.

A true electrical engineer would know that this modem is designed for locations with up to two IP addresses; it’s not a switch, it’s not a router. Basically, again, for businesses or homes which need or prefer to have two IP addresses.

I had complained with Comcast because everyone from customer service to tech support didn’t know this as well. If you need an extra IP address, it may be difficult finding someone who understands. Otherwise, when you take the human defective thought out of the equation, it’s an awesome modem for homes with midrange internet speed requirements.

Again, it’s the limits for comcast which made me upgrade to a faster modem.

Purchased the CM1100 because it specifically advertised “Gigabit Ethernet Ports – Fastest wired speeds to connect your router or computer. Create two home networks both capable of gigabit speeds and aggregate for the fastest Multi-Gig speeds” and box also indicated “2 Gigabit Ethernet Ports”.

It does have 2 ports BUT apparently only supports one home network (doesn’t act like an internal ethernet switch). I wanted to connect a router to one port and use the other port to hardwire connect to a computer.

I am an electrical engineer and after trying to get both to work for over a day (note: getting one to work would somehow disable the other network) I called customer support thinking the problem was perhaps due to IP addressing and modem configuration.

The router I was connecting to was a Netgear WiFi6 mesh. My frustration grew when they told me that it had nothing to do with IP addressing, the second LAN port was only for link aggregation and there was no way to connect two home networks directly to the modem.

Whether the CM1100 description was misleading or customer support was ignorant really doesn’t matter…it is inexcusable and is in part the reason for the 2 stars. The other reason for the 2 stars is because of the effort I had to put in to circumvent this hidden modem limitation by getting a separate ethernet switch and incorporating house wiring.

1Joe gave this a bad review because he is incompetent and doesn’t know anything about networking. It has nothing to do with the device. If a device is only a modem, not a router/modem combo, it has to connect directly to a router.

A modem has no routing capability. That’s what a ROUTER is for. It is not netgears fault this “electrical engineer” doesn’t understand simple home networking.

Purchased this CM700 32X8 DOCSIS 3. 0 modem to replace a 1 year old Arris Surfboard 32X8 DOCSIS 3. 0 Modem. The Arris had failed within 1 month of purchase – which Arris replaced with (seemed like) a refurbished unit.

9 months later – still under warranty – Arris refused to replace because it was the same problem(?)!. Replaced with the Netgear cm700. Quick easy setup. Speed seems quicker. Netgear has the app to control both modem & Nighthawk router.

Had 1 question & Netgear support answered quickly. Have always had good experiences with Netgear products. Only bought the Arris as it was recommended by a friend as ‘better bang for the buck’. Never again.

This modem paired with the Nighthawk router gives great wifi coverage throughout the 2 story home – no dead spots.

Bought the modem in March to try and avoid paying monthly modem fees with xFinity. The modem worked flawlessly until 5 months later in August when it suddenly stopped connecting with the xFinity service.

All troubleshooting narrowed the problem down to the modem (an xFinity modem connects fine). Trying to get an RMA with Netgear has been extremely frustrating. Netgear seems intent in throwing as many hurdles in front until you finally just give up.

Congratulations Netgear in getting my money for a modem that only lasted 5 months. It’s a shame, too. I used to like Netgear equipment, even for use at a company where I decide on equipment purchases as their IT Director.

The NETGEAR- 32 x 8 DOCSIS 3. 0 Cable Modem Is SPECTACULAR! The performance has made a HUGE difference in my gaming & internet experience. For the price you just can’t beat it. The size is actually a bit smaller than I expected which is good as it fits PERFECTLY right where I need it.

Before I purchased this modem the problems I was having while gaming was very frustrating. It was to the point of INSANITY! I called my Internet provider and we took my speed test which was ridiculous for the amount of GBPS I was paying for each month.

Even the Customer service Rep was shocked. She then affirmed the fact that I needed a new modem thus I told her of the NETGEAR -32 X 8 DOCSIS 3. 0 in which I had seen some good reviews for. Additionally It’s compatible with my internet service provider.

Upon receiving this modem it was a breeze to set up, I simply called my ISP & read the numbers/letters model etc. All done within 3 minutes. We ran the speed test & WHAT A TREMENDUS DIFFERENCE this modem made! Within minutes I was gaming like I hadn’t gamed in years.

This modem is the wisest investment I’ve ever made to accompany my hardware. The delivery time was Incredible as I had ordered it one evening & the modem was delivered to my door the next afternoon at 1:00 pm.

Overall I’m EXTREMELY PLEASED with the performance, size & look of the NETGEAR-8 DOCSIS 3. 0 Cable Modem & it’s perfect for my Ethernet set up.

Upgrade on an Xfinity/Comcast Motorola Surfboard from over a decade ago, has seemed to function without issue since day 1! Next planned purchase: a WiFi router upgrade that has LACP-IEEE 802. 3ad link aggregation to take advantage of the secondary gigE port.

I really appreciate that it even offers that, even though I prefer being in areas which have FTTH and 10gigE or better (SGI was doing such things in the 1990s after all, and Mellanox has 200Gbps adapters, whilst even Intel is playing catch up with 100Gbps ethernet now and NICs don’t cost much more than these ancient slow DOCSIS cable modems reliant on intrinsically slower than fiber and optical light based interconnects, copper wiring.

) Albeit, in SOHO consumer gear, that means another $300 or $400 in equipment just to theoretically get to 2Gbps, which I am more or less certain Comcast doesn’t guarantee or charges through the nose for, meanwhile well over a decade ago I was paying less in gear per gigabit ethernet port with fiber trunking from better ISPs, but when in hell, at least make it run faster! So, this is a definitive upgrade from the older modem.

The power switch, is also, wonderful, because in my experience, it is necessary to power cycle the customer premises equipment with this ISP quite often, and having to gothrough the hassle of unplugging the previous modem, just to power cycle it, was even more of a chore.

Good upgrade! Better upgrade would be moving to an area which has fiber to the home based ISPs e. g. municipal fiber for $500/mo/10Gbps in Atherton or $50/mo/1Gbps, and even cheaper offerings from Sonic and Cruzio in Santa Cruz and places such as Petaluma, but I do not currently reside in such regions as the real estate costs are also high.

I have been using my Netgear Modem for less than a month but so far it has been very reliable and has sped up my internet significantly. My internet service provider (ISP) was charging me $20 a month to use theirs and it was garbage! I bought this for less than I pay yearly to the ISP and I own my modem now.

It feels good to own the piece of machinery that is processing my personal information. I never felt secure leasing a modem from my ISP. On a side note, I also purchased a Nighthawk Router that sends the signal from that modem to all my devices and the user interface is very easy to navigate no matter what your experience level.

Purchased this CM1150V modem from Netgear. com in December 2020. It worked well for internet and voice until just after the 1-year warranty expired. At that point, internet connection became very sporadic and unreliable — sometimes on, sometimes not, and often showing as “not detected” on the Xfinity app.

Restarting the modem and adjusting connections wouldn’t fix the issue and the Xfinity technician who came to the house and checked the whole system diagnosed this modem as the culprit. I called Netgear to ask whether the warranty could be extended for another 3 weeks since it *just* expired.

I was told that such an extension may be a possibility as a one-time courtesy, though I’d have to run through troubleshooting with Netgear’s own technician before receiving a replacement. I spent a good 30-40 minutes on the phone as the guy ran me through restarts, a hard reset, and accessing the modem through multiple devices (via wifi and LAN) until the sporadic modem temporarily started working again.

At that point the tech declared “mission accomplished” and closed the case while I protested that my issue is with a *sporadic* connection. Nonetheless, Netgear’s courtesy gesture to me was now concluded.

And sure enough, within 30 minutes of the Netgear tech ending the phone call, the modem was inoperable again. I know 100% that this 1-year old CM1150V modem is the issue because my old modem (slower and lacking a VoIP) is currently delivering internet to my router without any problem at all.

Bottom line: This modem worked *just* long enough to get past the 1-year warranty and then went bad. And while Netgear’s support team initially seemed open to making things right, in the end I’m left with a broken, 12.

5-month-old $250+ modem and nothing from Netgear but friendly wishes for a good day. Very disappointed in both the modem and in Netgear’s support. Lesson learned, I suppose, and I’ll be purchasing future networking products from other manufacturers.

I purchased this modem in May 2020. It worked great for 6 straight weeks, not one issue. Then we started having periodic connection issues. I called Netgear and they attempted to help me troubleshoot the issue but kept blaming the ISP.

I had Xfinity out three times, they even ran a new line from the street to the house. I was still having intermittent connection issues. Finally, I decided to add a small fan next to the modem thinking that it may have heat issues even though this is in our normally cold basement.

Adding the fan significantly reduced our intermittent connection issues but they were not completely eliminated. Throughout this process I spent a total of 3-4 hours on support calls with Netgear. They finally agreed to replace the modem, which I had to pay shipping to receive it within a reasonable time ($$).

The new modem again worked for a few weeks without issue, long enough for the support on my original purchase to expire. The modem is still under warranty but you have to pay them for support to get warranty assistance.

The fan trick made things worse with the replacement modem. If the fan is within a foot of the modem I lose my connect nearly instantly, it must have zero EM shielding, weird that the original did not have this issue.

I then rented Xfinity’s modem for the past 2 months and have had zero outages, none, not one issue. I then reinstalled the Netgear. Again, it worked fine for a couple weeks but then the intermittent issues returned.

We have twice lost the connection completely, having to reboot the modem to get connected again. So either the replacement modem is also defective or Xfinity is triggering issues to get us to pay their rental fees.

Having owned a previous modem for several years that worked flawlessly I highly doubt the issue is with Xfinity. Unfortunately, I had to replace that modem to support the faster service I upgraded to.

Now I am stuck with a very expensive brick modem and having to still pay rental fees to maintain a reliable connection, which is clearly what I was trying to avoid by purchasing this modem.

To tell you about my modem, is quite the story. I started working from home, along with my girlfriend, the equipment from Comcast wasn’t even coming close to do what it was supposed to do. So like anyone who had some extra money and is now dependent on their jobs from home, I dropped almost $600 for this modem and a router system since this modem and other modems alike didn’t project a WiFi signal for voice over with Comcast.

I installed everything 07/15/2020 and it all had worked flawlessly, until 10/03/2020. This is when my nightmare began. Over the course of a week and a half, and almost loosing my job, having Comcast come out and inspect out internet feed, and being told it’s not the internet feed, but our modem.

I spoke with SEVEN different actual tech people at Netgear, finally the seventh person had agreed that it was the modem itself was bad and sent me a form for a new one. Now you might think that’s not too bad, but for that week and a half I was resetting my modem 2-3 times a day EVERY DAY.

After the fact not only did they submit my information wrong on my first call, by misspelling my name, my email and putting in the WRONG purchase date and being made to provide proof that it was purchased on the 15th, is without a doubt the most ridiculous hassle I had to go through.

You only have a 90 day phone tech support, if you have a case open prior to the 90 days they don’t care and will force you to buy more phone troubleshooting protection to resolve your issue. You must talk to a tech to get it replaced within the year.

So now fast forward to my replacement, it has been installed and has been working flawlessly. Would I buy it again? No, nor will I ever buy anything from Netgear ever again, all from the HORRIBLE SERVICE I had to go through, to have my problem resolved, that should have been resolved on day 1 of my series of calls.

I’ve been on the phone with Arris and Xfinity too many times since I purchased this modem/router almost 2 years ago. Since it’s still under the 2 year mark, I finally insisted with Arris that I needed a new one and they just sent it.

I had to pay for it ($200) plus $20 in shipping but the agent told me I’d get a refund once they receive my old product. My main problem was that Arris said the signal levels were off, which is why I kept losing internet connection.

Xfinity came out to fix the signal levels twice, adding a splitter on the outside, then on the inside of my house. Both times they said they could not reach the ideal signal levels that Arris insisted they should be at.

I’m almost ready to give up and pay the $14 per month rental fee for Xfinity’s gateway. But I’m so against the idea of renting something we should be able to buy. So far the new arris is working without as many event logs.

This is not a cheap router but it is extremely robust, and has a long range for wide coverage. It covers my entire 3 story house with all three wireless networks. Did not score quite a high as a couple of other AC3200 routers on the 5gHz band speed wise.

But it has not been noticable. Buy this router if you have a lot of devices spread over a large area.

Must have high speed internet to access full speed potential. Anything below 500 not worth buying. But of you’re in the 500 to gig, its a must have. So far very reliable.

The Nighthawk C7800 delivers incredible WIFI speeds! Even the Ethernet is much faster and it was a snap to connect. Only took 15 minutes.
