What do you mean by "stalling"?
Is the box frozen? Is the network unreachable?
What does /var/log/messages say?
What does ifconifg and route -n show during the stalling?
Is the a problem with communicating with your local network or with the ISP?
I have a similar setup as you. I use comcast.net, too, and basically I 
have gotten a static ip from them. They give an infinite lease. I used 
dhcpcd, and although it is supposed to run in the background, the 
obtaining of an infinite lease makes it terminate. I imagine if dhcpcd 
were running all the time, from time to time, I might get a new IP and 
that would certainly complicate my router situation. Is your machine 
getting a new IP from time to time? Would your firewall be a problem?
Instead of rebooting, have you just tried telinit 1 ?
