Just more of the obvious stuff:
You say it's a new cable modem, there is a home router, and there is at 
least one other Debian Wheezy box.
Does your ISP provide you with one, or more than one IP address? If one, 
the router probably translates this "public" IP address to your 
"private" LAN. Does the router function as a DHCP server, or do you have 
a dedicated box on your LAN? Can you check the logs of your LAN DHCP 
server for entries matching the non-functioning box?
