Works great. I bought this to replace my Arris SBG7600AC2 (which I also love) for 1Gpbs internet and I've heard so many good things about the WiFi6 being so much better. I almost didn't buy this because I've seen so many reviews about the connection drops many times during the day. As soon as I logged into the Admin webpage (http://192.168.0.1) I could immediately see why people would misinterpret this (sort of). Under Connection -> Local IP Network ->IPv4 (and/or IPv6) you'll want to change the DHCP Lease Time. By default it is set to every one (1) hour. When the modem release and renews connected deviced you might notice a momentary hiccup in the connection. Change this to about every 7 days. There is even a "Forever" option you can choose that will never renew. Attached is image of what I recommend that you change. Again by default this was set to every 1 hour.

If you are not totally tech literate, it may not be as easy to set up and connect all electronics to it. Some of us had issues but their Support is great.
