Running Ubuntu 10.04 and Windows 7 on a dual boot machine with a wired connection to an Airport Extreme router using basic DHCP. Windows connects without problems all the time. Ubuntu will not connect unless I unplug the power to the router and plug it back in (not a popular thing for me to do). The Airport is wired to a cable modem and maintained by someone else from a different machine.

I have tried to unplug/replug the LAN cable, disable/re-inable networking in network manager, delete old and create new connections (AutoEth0 etc.) in network manager, reboot, etc. No joy.

This problem began back in Karmic on a different motherboard so it isn't an old/new hardware issue. I had a bridge router for a while -- Netgear -- that worked okay but it is gone now. That makes me want to say the problem is in the Airport but the administrator of the Airport says no way, everything else works fine.

I have consistantly upgraded so I'm wondering if maybe some ancient setting in a config file somewhere gets in the way. It feels like the Airport just won't pay attention to Ubuntu.

Any ideas or suggestions? Be kind please, I'm weak with terminal commands though not completely inept.
