I want to replace my existing modem DPQ3212 with a Docsis 3.1 modem, for instance an Arris Surfboard 8200. However, since the 8200 does not have any phone jacks, I do not know what to do to retain Cox's voice service. I cannot get a clear answer from Cox - it seems I must buy or rent one of the "Cox-provided" modems, e.g., Arris TM3402. Is there any feasible option where I have my own Internet modem yet retain the Cox voice service? Thanks.
Is there anything wrong with your Internet and Voice service now? If you have good service, I wouldn't change anything. In fact, a few subscribers have posted about worst service after upgrading to a D3.1.
If it ain't broke...
Thanks a lot for your replies. After years of generally reliable service, I experienced Internet outage every 3-4 days for the past month. I figured maybe my 9-year modem needed replacement, The service is decent when it works, which is for most of the time.
Your outages could be anything: Cox, modem or router.
The next time it occurs, try connecting a device directly to the modem for any connectivity. If no connection, you could email (recommended) to check your circuit.
