Re: DPC3941T Gateway ethernet ports not working

I had a perfectly functioning DPC3941T and Comcast notified me that they were sending me a replacement.  I received an Arris TG1682G, sent back the Cisco.  I got the Arris added to my account and haven't had any issues with it.

DPC3941T Gateway ethernet ports not working

One port works fine, but none of the other three work at all, no lights, no connectivity.  When I pull up the LAN Hardware profile on the router, it shows both ports 1 and 2 as "Active", and ports 3 and 4 as "Inactive", but only one port will actually function.  I have verified that the router is not in Bridge mode, and I am at a loss as to why I can only get one ethernet port to work at a time...
