A number of months ago, I tried to upgrade my ARRIS DOCSIS 2 cable/phone modem to DOCIS 3. Comcast sent me a device that also had its own wireless router. I wanted to continue using my own router. After many hours on the phone, we were never able to get the new combined device to work with my router. I ended up just going back to what I had before after many wasted hours
I wanted to see what the current situation is with this. An Arris TM822 would solve the problem but its unclear whether Comcast would provision that device if I bought one and my local store does not carry them.
Anyone have any luck getting the combined modem/phone/router devices to work with an existing router? Which device should I be asking for.
I can't be the only customer that wants to use their own router but also has the phone service. If I didn't have the phone service, any of the non-telephony cable modems would work.
