Great Upgrade/Replacement for Xfinity!
By JJ on Reviewed in the United States on June 8, 2025
Took 20 minutes or so to set up with Xfinity. I just plugged it in with all the cables and got on the Xfinity app, added the new equipment using the app, and that was it. Then configured it on the desktop for the wifi. Easy. The instructions stated that another IP address needed to be configured, so I had to search and use 192.168.0.1, which I accessed without any issues. An old modem was limiting the speed, now it is super fast!

Update: Drops 2.4GhZ constantly, poor support,No WLAN button, refurbished units need a factory reset
By Tessa Ellis on Reviewed in the United States on January 25, 2023
Update: This is terrible I regret getting a modem/router combo. If one fails you are in a bad spot. I use smart home devices that primarily use 2.4GhZ only and the router keeps dropping the signal; nothing works; things reset. Arris support? They want me to send it back after verifying it was faulty *without sending a replacement* so I’ll just…. Have no internet? That, or I have to pay the full cost until they receive the old one. I can’t do that right now. I can’t afford to have this fail and can’t afford to front the cost of a second unit. I got a refurbished SBG8300-RB DOCIS 3.1 WiFiunit and it was about $120. It was impossible to change the network name or password until I found the number for support in a PDF manual online. . There is a hole at the top in the back you must press and hold for 15 seconds until it resets. Otherwise, it will ask you for the email of the previous owner when trying to log in. This should have been done while refurbishing the unit. There is also no WLAN button, which you can click on some models which makes it search and pair with devices easier. Without it, connecting things like a printer is a tedious process.
