Are you back on with the same address as before?
If so, I doubt it's dhcp _per_se_ that is causing the trouble; however
killing and restarting dhcp does have the effect of dropping the default
route and then re-establishing it. I would suspect that the default route is
somehow seizing up.
Next time it happens do a "netstat -nr" and trying "pinging" your default
gateway.
PS: I'm assuming from the what you describe here that you are connected
directly to the cable madem without a firewall in between, right? (If so I
hope you were careful with your machine's setup to not have any ports open .
. .)
