I am running Ubuntu 12.04 on a Toshiba L450 and I am unable to get wireless connection.
On booting I quickly saw the wireless connection for the house come up under the wireless icon and then it vanished before I could connect to it. the enable wireless option is highlighted to start with but when I click it it becomes greyed out.
network shows aeroplane mode on but switching to off doesn't change things and I am unable to flick wireless to on.
Lshw shows DISABLED and iwconfig wlan0 with Tx-Power=off
have tried FN F8 to switch wireless on to no effect?
Any simple ideas out there?
Rfkill list all shows wireless LAN hard blocked: yes
