Bug seems to affect me too, but I cannot see any networks at all.

zeekoe@zeekoe-d630:~$ sudo iwlist scan
[sudo] password for zeekoe:
wlan2 Interface doesn't support scanning : Device or resource busy

(now I disabled the device by hardware button)

zeekoe@zeekoe-d630:~$ sudo iwlist scan
wlan2 Interface doesn't support scanning : Network is down
zeekoe@zeekoe-d630:~$ sudo ifconfig wlan2 up
zeekoe@zeekoe-d630:~$ sudo iwlist scan
wlan2 No scan results

(and it stays like that. NetworkManager does not see any networks either)

...if that may help.

After that, I tried mainline Linux 3.4.0-030400rc4-generic-pae (as suggested in #989473, I picked pae because I might add some more memory soon), in which my wifi worked flawlessly. However, with that kernel, my laptop did not wake out of its sleep, at least not my monitor (perhaps because of dkms/nvidia issues?). Now I returned to:

zeekoe@zeekoe-d630:~$ uname -r
3.0.0-17-generic

...from oneiric/11.10, in which everything works perfectly.

lspci reports my card as:
0c:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe

I'm not sure what card it actually is (it came with an Eee 901).

Not sure how I can add a tag? But, to repeat, this particular bug was fixed in mainline 3.4.0-030400rc4-generic-pae.
