router borked?

[GhettoFob]

Hi, I recently switched from DSL to cable internet and I love the speed. I do have one problem though. After a few hours (or days) I'll be unable to resolve dns. I've tried switching the servers I use to no avail. However, a quick reboot of the modem always seems to fix it up. I'm pretty sure it's not the cable connection itself because existing dowloads are just fine and I remain connected to AIM the whole time, I just can't connect to any new webpages. Is my router just dying or is it something wrong with my cable internet (which I doubt).

Some ISPs have unreliable DNS servers. You said you've tried switching your DNS servers. Have you tried using DNS servers that do not belong to your cable ISP? Try putting in these DNS servers into your router and see if the problem goes away:
216.27.175.2
216.231.41.2

ok, I'll give those a try. Also, is there a linux equivalent to ipconfig /release and ipconfig /renew? I'm running gentoo if that makes a difference.

I think you can use ifdown eth0 and then do ifup eth0, if the network adapter is eth0. not sure if there is one command to do that though, I try to stay away from linux.
