I use wpi0 to get to the net and never had issues until now. I get IP from the DHCP pack of the ADSL modem. But can't connect to the net. If I ping mit.edu I get: ping: sendto: No route to host ping: wrote mit.edu 64 chars, ret=-1 then I have to do dhclient wpi0 and get issued an IP and ping mit.edu works for about 5 seconds and then I start getting "wrote mit.edu 64 chars, ret=-1" error again. And then if I do "dhclient wpi0" again I get "Can't find free bpf: No such file or directory exiting" and then I have to do "ifconfig wpi0 down && ifconfig wpi0 up && dhclient wpi0" and I lose connection again in 5 seconds and repeat the same.
Thanks for any help.
