So, here is what I have:
> ~ $ sudo rfkill list
> 0: phy0: Wireless LAN
> Soft blocked: no
> Hard blocked: no
> ~ $ sudo rfkill block 0
Wifi immediately loses connection, wifi led turns off and dmesg reports:
> wlan0: deauthenticating from 00:23:69:2f:3f:01 by local choice (reason=3)
Now I have:
> ~ $ sudo rfkill list
> 0: phy0: Wireless LAN
> Soft blocked: yes
> Hard blocked: no
Unblocking:
> ~ $ sudo rfkill unblock 0
> ~ $ sudo rfkill list
> 0: phy0: Wireless LAN
> Soft blocked: no
> Hard blocked: no
But wifi is not functional, wifi led remains turned off, dmesg tells nothing.
If I turn hardware switch off and on, and then software off/on nothing changes.
Then I compiled 2.6.34_rc5 kernel and get same behavior. Also I have
got additional
entry in dmesg when turning wifi off with rfkill utility or with
hardware switch:
> cfg80211: Calling CRDA to update world regulatory domain
Thanks for quick response!
