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.

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! -- Grygoriy Fuchedzhy
