Co to za model laptopa?
Próbowałeś bawić się skrótem klawiaturowym załączającym/wyłączającym kartę?

[ww71]

Jeśli masz zainstalowany obok network-managera program WICD do netu, to jeden trzeba odinstalować. U mnie jest tylko WICD.

[arturromarr]

Tak, była zablokowana skrótem klawiaturowym.
Jest pod klawiszem F2 jak wejście do biosu i pewnie niedokładnie przytrzymując Fn zablokowałem kartę.
Wielkie dzięki za pomoc i przepraszam za zamieszanie z takiego błahego powodu.
Jedno jest pozytywne, że czegoś się dowiedziałem o funkcjonowaniu karty w systemie.

PS:
Jedno mnie zastanawia czemu:

Kod: Zaznacz cały

root@debian:/home/artur# rfkill list all
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

nie wykazało zablokowania karty?

Jeszcze raz wielkie dzięki.

[dedito]

Też nie rozumiem dlaczego rfkill nie wskazywał tego.
Dopiero ostatnie dmesg naprowadziło na tą błachostkę.
W każdym razie proszę oznaczyć wątek.
