mam problem z wlan0:

Code: Select all

lspci
04:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
gdy mu wklepie:

Code: Select all

iwlist scan
to wysypuje błąd:

Code: Select all

lo        Interface doesn't support scanning.
wlan0     Interface doesn't support scanning : Input/output error
eth0      Interface doesn't support scanning.
ppp0      Interface doesn't support scanning.
dmesg wyświetla:

Code: Select all

No ale jak poczytam w/w dmesg i dodam rfkill:

The open sources iwlagn driver need a proprietary firmware to work :'(.
# emerge net-wireless/iwl5000-ucode
Sprobuj tez moze po prostu:

Code: Select all

# ifconfig wlan0 up
# iwlist scan

Ja uzywam do skanowania i zarzadzania sieciami WICD. Na zen-kernelu jade - jednak ja nie posiadam takiej karty sieciowej WiFi jak Ty, ale wg opisu autora powinno cos takiego zadzialac. U mnie o dziwo w lapku jest karta atheros, do ktorej musialem doinstalowac acerhk(!?), mimo ze lapek to fujitsu siemens li 1718 - z tego powodu, aby system mogl obslugiwac - a w zasadzie wlaczyc diode od WiFi, kombinowalem juz kilkanascie razy i nie da sie inaczej tego zalatwic. Wiec byc moze...to sa klawisze dodatkowe (jakies) ktore powoduja brak poprawnego dzialania karty sieciowej. Jednak takie przypadki zdarzaja sie raz na n-modeli, co nie zmienia faktu ze sie zdarzaja. Sprobuj moze wpisac model laptopa i poszukac WiFi na googlach - moze komus udalo sie to ladnie opisac i skonfigurowac pod Linuxem.

Code: Select all

iwlagn 0000:04:00.0: Radio disabled by HW RF Kill switch 
Czyżby radio było wyłączone? Spróbuj pokombinować w biosie. Tam jest na pewno coś na ten temat. Możliwe, że uda się włączyć radio na stałe. Jeśli to nie będzie pomagało to kombinuj z opcjami modułu przy modprobe. Ja mam inną kartę ale u mnie wstaje jak dam:

Code: Select all

modprobe ipw2200 disable=0 hwcrypto=0 associate=0
A i killswitch musisz mieć w kernelu.
