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

Please provide the output of rfkill list and lspci -knn | grep iEA3 "(wireless|network)". And what does sudo rfkill unblock all change about the output of rfkill list? – gertvdijk Jan 28 at 10:32
Stupid I know - reset the BIOS The solution is a reboot. Hit F2 to enter bios, then F9 to reset, then F10 to save and exit. Your wireless should be working at that point. Thanks to: thecowgirlcoder.com/2012/10/18/… – paulisabout Jan 28 at 10:46
