Router Internet Connection Problem

Here's the situation:

1)We had some internet service problems, and have recently replaced our
cable modem...

2) When connected directly to the PC, there is no problem accessing the
internet (i.e. this is not a problem with our Comcast connection)

3) We are using a USR8054 Router -- the network seems to work just fine
-- the router recognizes all PC's on the network, both wired and
wireless

4) Connections seem fine -- the cable modem shows that it is connected,
and the USR router has the "WAN" light solid (i.e. it is picking up a
signal from the cable modem)....

5) No DHCP address is detected by the router -- i.e. although the
internet connection seems to work fine when connected directly to the
PC, for some reason the router is not picking anything up.......hence,
can't connect to internet via router.....

Have tried resetting router, resetting modem, renewing IP....no
luck......fixed IP is not an option.

Am at a loss about what to do next....suggestions??/

 

This sounds like the router needs to clone the MAC address of a NIC
maybe. Still it is off topic as this newsgroup if for the Microsoft
broadband networking hardware & related software only.

A common mistake that people make when trying to design something
