I just installed an Ubuntu system on a Comcast connection yesterday for
a friend. I found that I had to turn off the Ubuntu system, then the
Comcast modem & leave it off for about 60 sec, and then turn it back on,
let it settle, then turn on the Ubuntu system. You may also have to do
the same with your linksys. The Comcast modem cable (Token-Bus) modem is
a very basic modem that records the nic of the connecting machine. If it
gets confused, you need to repower so it will rerecord the mac addresses.

So, try powering everything off for at least 60 seconds (removing power
cord to the Comcast modem). Power up the Comcast modem, let it settle.
Power up the linksys, let it settle. Power up the PC under Ubuntu. See
if that works. If that does not, post back and we'll try  a few other
things.
