Review on 📶 Arris SURFboard SBG6950AC2 - 16x4 Docsis 3.0 Cable Modem Plus AC1900 Dual Band Wi-Fi Router - Certified for Xfinity, Spectrum, Cox, and more - Black by David Romo

tl;dr: This product failed after two months and Arris is making it almost impossible to replace under warranty. I bought this modem to replace another Motorola/Arris model that has served me well for several years. The modem was easy to install with Comcast, although it was a bit confusing as there were two MAC addresses below and it wasn't clear which one to use. So I had to go through the installation process twice. Configuration is pretty easy with the included web interface, so no complaints. The Wi-Fi signal also seemed pretty strong, although I ended up adding a hotspot upstairs in my house because it couldn't get to my home office. The modem worked fine for about two months. But about a week ago my network started to crash and I had to restart it several times a day (although the lights on the modem showed a working connection). (Note: there are many other reviews on here stating the same thing happened to other people.) Not only that, my home network will be down as well. The router is almost frozen. Of course, even if Comcast had problems on their end, it shouldn't take down my entire network, right? At this point I tried to do a factory reset but the same thing kept happening. So I called Arris Technical Support. In short, Arris tech support blamed Comcast (the signals were too strong), which in turn blamed Arris (and scoffed at the idea that they could just "turn off the signals" at Arris' suggestion). ). I even hooked up a splitter to the line to get the signal strength in the right range, but it worked. The Arris tech tried to blame the wiring and said I needed to call a tech. I pointed out that I would have to pay for it and that Comcast would probably tell me everything was fine (I have fairly new wiring and very reliable, high speed up until last week) and even then it doesn't explain why my internal network keep falling. I asked him exactly what to do to convince him it was the modem and he refused to answer other than saying we needed to do more troubleshooting. (And honestly, what other troubleshooting steps can you do besides a reset?) I've been on the phone with Arris and Comcast for a few hours at this point and just gave up (I think that's what they intended) and another bought brand of cable modem and so far everything has worked fine.
