[WiFi] Intel Centrino Advanced 6235 (error 45)

[Harald Brinkhof]

If you have an android phone you can turn on usb tethering and let it
wifi-connect to your network while you connect the phone to your laptop
with usb.

It'll create /dev/ue0 and you just need to issue

dhcpclient /dev/ue0

(as root)
To get everything working as an ad interim solution.

Hope it helps you out a bit.
