Wlan

Hej
Har precis installerat nya unbutu
Fick tyvär ett problem som jag inte hade väntat mig,
funkade i den äldre versionen.
Trådlösa nätverkskortet gick inte igång =/

dmesg |grep Wireless
17179600.176000] ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux, 1.1.0mp
[17179601.408000] ipw3945: Detected Intel PRO/Wireless 3945ABG Network Connection

sudo ifconfig eth1 up
eth1: ERROR while getting interface flags: No such device

Någon som vet vad felet kan vara?
