I've got an Intel 1000 Wireless N chip:
It connects to G networks just fine. But will not connect to a Wireless N AP.
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000
iwconfig suggests it's only doing b/g:
Firmware is up to date.

I tried Arch-Linux on this same laptop and got it to do N just fine. Even got up to 130Mb/s in iwconfig output!
1) Firmware is good, same as Arch linux
2) AP is good, others connect fine at N speeds
3) G connects fine, so not authentication or other logical problem...
What should I look for?
Ubuntu 10.10 64 bit
