I'll second that, using Comcast through a Moto SB5100 modem. I can dual
boot between Windows (ok, it's '98, not XP) and Linux (F7/8) all day
with no problem getting an IP, but if we try to plug in a different
device (XBox, laptop, router, etc.), the modem has to be power-cycled
before it will give out an address. So far, that's all we've ever had to do.
It's all behind a router now, so it doesn't make a difference any more.
