I'm using ubuntu 11.10 for a couple of months.
but Today after restart my laptop I can't get wireless on. I tried to install windows wireless drivers but it didn't work too.
and It's not off by rfkill
too.
# rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 2: dell-bluetooth: Bluetooth Soft blocked: no Hard blocked: no
when I tried
# ifconfig wlan0 up wlan0: ERROR while getting interface flags: No such deviceand
# lshw -C network *-network
