I'm using network manager to connect. Also, tryed iwconfig. Results are same. I even try to connect to open access point — results are same. More information:

At this moment I try to connect to open wifi ap:

My distribution:

Drakmail@thinkpad-x220:~$ cat /etc/*version
AgiliaLinux release 8.0.0 (Sammy)

(Something between Slackware and Archlinux).

Also, I saw that wifi module to often trying to load a firmware file.

Any ideas what it would be?
