Most cable modems lock to the first MAC address that is connected to
them. You have to power cycle the modem every time you connect a new
ethernet port to it.

Most DOCSIS 2.0 modems have a diagnostic page at http://192.168.100.1
that you can check out to see modem connection status.

I'm not sure if you're still connected through the router, or directly
to the modem - could you better describe your current network setup?
