For the 3.7 kernel:
sudo iwconfig
pan0      no wireless extensions.

wlan0     no wireless extensions.

lo        no wireless extensions.

eth0      no wireless extensions.

sudo iwlist scan
pan0      Interface doesn't support scanning.

wlan0     Interface doesn't support scanning.

lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

For the official ubuntu kernels these commandos behave as expected.
I am really desperate.

Maybe I have to re install in order to get trim support via xfs or ext4
(although I prefer to keep jfs)
