Conclusion
The bottom line is that the best WiFi modem for Spectrum is the one that can give you the speeds you need for the devices you have. If you have a lot of devices that need a lot of speed, then you’ll want to get a modem that can handle that.
Otherwise, you might be better off with a more basic model.
