Arris TM3204 Problem.

 I recently had my phone service changed to VoIP. They installed an Arris TM3204 modem.

The phone works fine but my internet keeps going down. The modem is connected to an Archer C8 Router. Within the first week the I had 6 no internet issues. The status lights on the modem indicated that the internet was connected. Power cycling the modem would bring it back.

The last time I noticed that the router was telling me "cable disconnected". I replaced the cable with no success.

Cox did a truck roll for the problem and the field tech didn't have a clue. He replaced the modem with a different one. It just did the same thing this AM. Router says cable not connected.

I connected direct to my PC and the PC said no connection. Power cycling the modem fixes it. Obviously there is something flakey with the ethernet port on this modem.

Any body else experience this or have any ideas?

    After more outages and investigation here's what I'm seeing.

      Sorry about this. Seems the interface to this forum takes enter as I'm done instead of new line.

      Here's my router info:

      Firmware Version: 3.17.0 Build 20150518 Rel.38024n
      Hardware Version: ArcherC8 v1

      The router is releasing the IP address and then Cox sometimes issues a new one and sometimes not. Here's the router log from a successful DHCP renew. As to why it takes 3 to 5 minutes is anyones guess.

      This never happened before the upgraded modem. 
      Power cycling the modem (and router if needed) forces a clean DHCP request.
      I'm getting a lease time of 86400 seconds (24hrs) but my router seems to be releasing randomly.
      I have another identical router and I'll swap it in to see if it's my problem.

      For now my workaround was to fix the IP address which will work until COX decides I need something different. Not sure how long that will last.
