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?
Thanks, email sent.

I thought you said he replaced it with a different one? Either way, what kind of IP or error do you get when you connect a PC direct to the TM3402? Last, the TM3402 only has 1 ethernet port on the back right?
You said a power cycle fixed "it". What is exactly is it fixing? Does it not see the physical connection until you power cycle? Not get a IP address? Get a invalid IP(169.x.x.x)? I wonder if the people at Cox forgot to assign internet to it, and only assigned telephone.
Does the telephone service from the TM3402 also break when the internet does?
After more outages and investigation here's what I'm seeing.
