Anyone out there find any cable models that have voice jack but no router capabilities? I don't want to use the Comcast modem but I need the phone jack...but prefer to use another router (so the router built-in to the modem is useless for me).. any ideas?

The Arris TM822G is the newest modem without router functionality and with telephony capabilities.

However it's old, and not the greatest modem in the world from what I have read. It only supports 8x4 DOCSIS channels meaning you simply can't achieve particularly fast speeds (it's technically limited to no more than ~300mbps download and ~120 mbps upload).


Honestly you'd probably have better luck just disabling the features on the comcast modem you don't want to use, and then put whatever router you would rather be using after the modem.

You'll want to double check with your cable modem provide if they allow you to use your own cable modem for phone usage. Since it's not easy to find, I suspect most don't let you since they provide it to you anyways.

In my home it's a silly gigantic all-in-one cable modem/WiFi/voice box/4 port gigabit. When I 1st received it before calling them, I toyed around with it and saw all the options. Most I would have turned off. After calling to have them set it up as a cable modem bridge and voice only. I can no longer login to manage, but it is setup as a cable modem bridge with landline voice. The 4 ports work, but once you plug in one that gains access, the other just light up but don't appear to do much. By the way, it was free, no monthly charge and was at the max channels my cable provider supports so I left it be.

Any cable modem that has VOIP jacks and a router should be capable of being put into gateway mode. I forget what my brighthouse model was but thats what I did.
