After a few hours of using notebook+bcm43xx I was disconnected and was
not able to connect again. Even reloading bcm43xx module didn't help.
I had to reboot my notebook. It was quite weird because I usually
don't have any problems connecting to this network.
Before rebooting I made some logs of /var/log/messages and
/var/log/NetworkManager. It contains logs of two operations:
1) As root: rmmod bcm43xx && modprobe bcm43xx
2) As user using KNetoworkManager I clicked on "zajec_linksys" which
is my network
After that I was not connected and what's more I was not able to use
"iwlist scan" anymore:
# iwlist wlan0 scan
Warning: Driver for device wlan0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 21.
Some things may be broken...
wlan0 Interface doesn't support scanning : No such device
