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??/

You need to powercycle the modem not reset it. Ensure router is set to
default configuration, power off all components, wait several minutes,
power up modem, wait for modem to sync with comcast, power up router, wait
for router to sync with modem, power up computers. Wait times and sequence
are critical.

If this fails, go here and read the FAQ's/sticky

And, if Bob's procedure does not work,
you MAY need to go into the Router setup screens
and MANUALLY set the MAC address for the router to the
MAC address of the computer with which you successfully
connected to the Internet via the cable modem.

The modem "binds" (for lack of a better analogy) with
the first MAC address is sees and refuses to accept any
other - the router has its own MAC address different from
the one of the PC you used.

I *think* the power cycling procedure that Bob outlines
will erase the MAC address, but if it doesn't...

My link to the Internet is a DSL line but the same theory applies. I use a
dsl "modem" and a Linksys router/switch. The dsl modem wants one connected
device and that's the Linksys. To get the rest of my computers on the
Internet they go through the Linksys and the Linksys pretends to the dsl
modem that it is one "computer". You can also do the same thing with one
computer doing ICS that has two net cards and a big switch. It goes "modem"
-> computer -> switch. Then everyone connected to the switch can browse.

later.....
