[wsteven]

Hello all,

Coming here to try to get some help with my wifi alpha card. It just can't scan / connect. It can dump me data in monitor mode though.

Here are some outputs :

The card works fine on another ubuntu computer.
I installed firmware-atheros version from wheezy-backports repo to end up discovering the firmware was actually the same. Maybe I need a kernel update?

Any suggestion greatly appreciated.

Same issue with latest firmware 1.4

By any chance, anyone knows the limitation on usb power? Can't find the information anywhere.
