20 Best Cable Modem And Wifi Router For Xfinity (2023 Updated)

Excellent Router. Set up very smooth with Comcast. You can activate the device yourself using comcast app or web which is so nice not having to wait for support. Love the combo modem router as it eliminates a box and a power supply and the cabling from modem to router.

Also since these devices are made by the same company compatibility config issues are eliminated. Now I can easily move this device which is fairly compact easily from one area of my home to another if I need to.

One hint I would like to give the small pct of people who are getting dropped connections is to install a wall timer that reboots the router in the middle of the night. I had a R7000 nighthawk that seemed fo get messed up especially when connecting multiple times to netflix and or amazon prime.

The timer turns off at 2am and back on at 201 am. That solved all my dropped connection issues. I will see if I get similar issues with this router and if so I will plug it into the timer. So far (only 2 days) but working perfectly.

Wifi signal strength is very good and even a little stronger than the R7000 which is amazing as it has no external antennas. One more tip for those who do not see the 5g wifi signal. Change the “channel” for the 5g band from 156 to 48 or test other channels until the 5g signal shows up.

I was running an older DOCSIS 3. 0 router combo and needed an upgrade badly. I got a deal on the Nighthawk and instantly saw speeds increase. I was getting 100mb download speed at best on my PC Wi-Fi.

Now it’s 250mb consistently. That means way better range as my PC is in my furthest bedroom from the router. The Coax cable was a bit snug and took some maneuvering to get on. At least it’s on tight lol.

Most importantly, the Nighthawk app was a bit finicky when I set it up. After calling my internet provider to activate the modem/router, I still couldn’t get on the network. Make sure to download the app and make every attempt to login to the router and change your network name and password.

You can also do this from a web browser, but it has to be on the network first. Overall, I’m very happy with the upgrade. I didn’t find out it’s DOCSIS 3. 0 until after I set it up. I guess I don’t really need DOCSIS 3.

1 as long as this continues to work. Bonus: props to Netgear support for getting back to me quickly about registering an already registered product(bought it on OfferUp). They were effective at communicating and making things easy.

I’d buy another Netgear product because of that experience.

My internet provider is Xfinity and my plan is for speeds of up to 400 mbps. I bought this router to replace an outdated model which wasn’t compatible with my service—the old router was only delivering ~160 mbps download speed via Ethernet.

The Netgear Nighthawk was a MAJOR upgrade and easy to connect. Instructions & activation was straightforward and took >10 minutes total. Simply used the Xfinity app to activate, entered mac address located on router label, and boom setup+activation was complete, (no hellish phone calls to Comcast tech support needed).

Easily customizable WiFi name too. I performed some tests and was actually getting above the 400 mbps included in my Xfinity plan (~480 mbps via Ethernet connection). Has dual band transmitter (2. 4ghz + 5ghz) and the range is phenomenal.

Sleek design and well made. Very satisfied. 24×8 channels is a great value and provides more than enough speed to stream valorant on twitch while playing on the same pc with upwards of 144 fps consistently.

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.

I upgraded my ISP plan from 105 mbps to Xfinity’s 1. 2 gbps plan, this time I decided to buy my own modem instead of renting from Xfinity. I can confirm that this modem works perfectly fine with Xfinity (at least here in Chicago).

Set up was a breeze, I was able to set up the modem without having to have an installer come out by using Xfinity app and and activating the modem. It was actually a lot easier than I had expected, I was glad I was able to do it through the app and not having to call customer support.

The unit only has 1x 2. 5gpbs ports which l was able to get +1. 4 gbps speeds directly to my pc when hard wired directly to that port. You may need to upgrade your network card and/or your ethernet cable to achieve speeds >1.

0 gbps. Wifi works, but I have a home with multiple floors so there is a drop off in performance as you get further away from the modem. Right next the the modem, my phone was getting +550 mbps speeds.

As I reached the farthest corner of my house, the speeds dropped to +150 mbps. So depending on the layout and construction of your house the wifi may be great or you may need other methods for wifi. The telephone works as expected, but honestly I haven’t had to use it much.

The modem has a nice matte finish and a relatively medium foot print. It’s LED’s are bright and informative. The web interface is pretty standard, with descriptions for each option of you hover your mouse over the question mark.

The Moto Sync app is a pretty decent app and relatively user friendly. You can set parental controls, block (or allow) websites, set schedules and even turn on or off wifi to specific devices on the fly.

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.

Initially easy to set up except for 2 major problems. This router is not initially configured to work well with airplay. If you use airplay to stream music or video around your house, beware. My research shoed that many other people have had the same problem, including in the Netgear support community.

Netgear support was polite but of no help as they never seemed to understand the issue. I eventually stumbled onto a solution that solved the primary problem here at my house after many hours and much stress.

But that led to the next issue. THis router does not have the ability to automatically select a good 5ghz channel. It has auto for 2. 4 but not 5. This means you will spend additional experimenting with channels to find one that works well for airplay in you house.

And when you find one it will probably only be a temporary solution and you will eventually be looking gor another channel. It is ridiculous that this unit does not have auto channel select for both,a technology that has been around for long time.

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.

Although I bought the device from Best Buy I thought it was important to share my experience with the C7800. I don’t typically spend the effort to write reviews but feel it was important to in this case.

My apologies in advance for the length of this review. I’ve had other Netgear devices that have performed well, but not the C7800. On June 9th I purchased the modem/router after a lightning strike took out lots of my home electronics.

I struggled for several weeks trying to get my smart home working reliably again. The root cause of my problem was the C7800 dropping 2GHz WiFi connections periodically. Then its SSID would disappear so you couldn’t even log the device back it.

Another reboot and it was live again. By this time, it was too late to return it to the store. After numerous tech support calls, chats and troubleshooting sessions I convinced them to send me a replacement.

(It shouldn’t have been that hard! It was clearly defective. ) The replacement was a refurbished device that had even worse problems. I have hobbies that include designing devices that are WiFi enabled.

With the refurb I was able to log into the C7800 without the router acknowledging my device in the attached devices screen in the router. A big security scare for me. Plus, the router kept dropping devices.

After many more discussions and troubleshooting sessions, they agreed to send me another C7800. I actually wanted them to send me a different lower cost router but they refused. However they did agreed to send me a NEW C7800 this time.

Unfortunately, they sent another refub that I didn’t even try. I returned that one and they eventually sent me another new C7800, again refusing to send a cheaper router to make me happy. I would like to say this one worked better but this device couldn’t give me a display of what devices where connected to the router 2 times in a row and get the same list.

At this time, I DEMANDED a different device. This was day 113 of my battle with the C7800 and Netgear. After that demand they ghosted me, so I finally went out and bought a Arris modem and Linksys router.

I had it working reliably in 2 hours (of which 1 hour was driving to and back from Best Buy). Finally at day 142 I heard back from Netgear as the case was still open. I told them the C7800 is in the trash where it belongs and close the case, I don’t want to waste any more time with you.

So just a warning. The device might work well for some simple applications but anything beyond that I would not recommend the device. I’m also concerned about its security. I offered to work with Netgear engineers to address the security concerns but the tech support person did not take me up on the offer.

So I’m not so happy with Netgear as well. Just for reference I feel competent in my analysis having 2 degrees in Electrical Engineering and Computer Science and a 35 year technical career.

The Nighthawk R6900v2 that I bought a few days ago is quite an upgrade from the ancient ASUS RT-N16, meaning that it’s much faster and had far greater range. I finally have full Wi-Fi coverage throughout my house, as well as my yard.

The only con I have is that in order to opt-out of Netgear’s data aggregation, one must send them an email, rather than simply including an opt-out button within the router’s settings. That is really the only gripe I have with my Nighthawk router.

Well, that plus setting it up the first time revealed some major glitches (not accepting my password after upgrading the firmware via their app – I had to reset the router back to factory defaults) but I got it all sorted out.

eventually. Once the headache of setting up the router has been completed, it is a competent piece of equipment. Even though both the Nighthawk and old ASUS RT-N16 have gigabit LAN ports, I have found that using the Internet is noticeably faster with the Nighthawk; it’s not my imagination either.

🙂 Would I recommend the Nighthawk R6900v2 router in spite of its setup warts? Indeed I would!.

I purchased Netgear Nighthawk X45 C7800 on 09/03/2020. It was working like a charm in the beginning. Then I started to have intermittent internet connection. I don’t remember the exact date it started to act up.

But it must have started from a few months ago (today is 11/10/2021). Most time, I just reset the modem/router combo, and it will have no problem for some time. Finally, it reached the critical point and needs reset more frequently.

I gathered my courage to call Comcast/Xfinity — the call was never pleasant since it is the sole provider in my town. The lady did some diagnostic check, and then told me that the issue is with the modem/router.

She can’t provide any evidence to me, but merely a ticket number. Then I checked the warranty for this device, and found out it was expired on 9/03/2020. What a bummer!! Maybe I should have called Comcast when it acted up for the first time? At the same time, I am amazed at the quality control of NetGear product.

It started to function improperly pretty much right after the warranty is expired. Is it a coincidence?.

When we first bought this modem we were really happy. It looks great, easy to install, no antennas and the Wi-Fi reached every single part of our two-story house. However, on the last year and a half our opinion has changed.

When the devices are connected to the modem on cable (like the tv) it works fine but if a cell phone is updating for example, the download rates go down almost to zero. We can’t do two things at the same time anymore.

The internet provided once said that we must change the admin password when the internet gets too slow because Netgear updates their software remotely and when it happens the connection comes back to dial-in levels.

Changing the admin password isn’t an easy task. You have to use the IP address and now that there is an app, you just can’t access the admin page. It happened just last week, I downloaded the new app, follow the instructions and nothing happened.

The IP address now send us directly to the app too in a endless cycle of anger and confusion. I don’t remember how I did it but it took me 1h30m to figure out a solution. So now we are not that happy anymore.

I will give it 3 stars because this is still a good modem with long reach but it is not outstanding anymore and it is failing us more and more.

I have had my modem/router for two years without incident until recently. I Purchased this because I did not want to have to pay a rental fee every month to the cable company. Recently I had trouble connecting to the Internet and the cable company assured me it was not on their side.

When I called Netgear, I waited an hour and a half on the phone just to speak to a tech support rep!!!!!!!! The gentleman on the phone was super nice and courteous, we went through how to reset the router, but still no Internet.

He assured me that the hardware was OK, but that I would have to purchase a tech agreement to check the software. That’s ridiculous! The tech agreement was nearly the price of the router/modem to begin with! I had no idea this was how Netgear operated! I thought that the tech would help you with troubleshooting the software as well….

NOPE! I told him, I may as well go out and buy a brand new modem router for the price of the tech agreement!! So after 2 hours (waiting an hour and a half and being on the phone for half an hour). I hung up the phone with no resolution! Fortunately, the problem resolved itself a few days later… The network popped back up working OK!!??? I do want to give kudos to the tech support guy on the phone though, I know his hands were “tied” By the NETGEAR company and he could only do so much without making me pay for a tech agreement.

He was extremely nice, polite and courteous.

Was having trouble with a Surfboard modem with a Netgear R6260 attached after doing the latest update through Nighthawk. Decided to replace it with a modem/ router combo, the C6250. Set up in Nighthawk kept stalling at the “firmware out of date” stage.

I was able to get into the settings through my MacBook but couldn’t find any settings to update it. Turns out with the modem, Spectrum is responsible for updating it. It had the latest update according to anything I could find.

Tried doing setup again, deleting the app, all of it. Nothing worked but oddly I was able to download the old Netgear genie app and that works fine. Just seems like I lost a lot of features that I was used to with Nighthawk.

Speeds seem the same as before and it’s not dropping the connection so all in all I guess it’s an improvement.
