Wireless erkannt, kann aber keine Verbindung zum Netzwerk herstellen. Wifi-Karte Intel Pro Wireless N100 BGN


Vielen Dank im Voraus, ich habe den Linux Mint-Kernel 3.0.0-12 x64 installiert, WLAN wurde erkannt und ich konfiguriere es im Netzwerkmanager, kann aber keine Verbindung herstellen. Es gibt die Ergebnisse der Befehlszeile:

$ iwconfig

lo        no wireless extensions.

eth0      no wireless extensions.

I think the problem is "tx-power off", you can try to type this:

sudo iwconfig wlan0 txpower 14

14dbm is the maximum tx-power for my card, I don't know your.

However, I think the card is powered off, have you turned on the wireless? :-)
