hi. i'm having a strange networking problem i've never had before on fc4. it often stops working completly or partially, either because i am listening to the radio from shoutcasts, or for no apparent reason. the radio continues streaming, but noting else works. when i stop the radio, i have to bring eth0 down and up again, which usually fixes the problem. sometimes, though, it won't resolve names correctly. i can ping my router, googles ip, but not domain name. however, i know my resolv.conf is configured right, as i can ping the servers in there. once, when i tried to set it with dhclient (which i never used before, i just found it in /sbin) it completly crashed the computer. i think this may have something to do with using ipv6, when i want to be using ipv4. i haven't been able to figure out how to change this though.
it also crashed once when i was trying to set the ip, broadcast, and mask for wlan0.
here is the output of my dmesg, i just rebooted my computer.
