Any one know how to hard unlock wireless adapter in Ubuntu 12.10

I have Toshiba Satellite laptop c640 with dual boot. The wireless adapter works fine in windows . But in Ubuntu it shows "disabled by hardware".

I tried rfkill unblock all . Then nothing happened to the lock.

I checked "lspci | grep wireless " it shows the wireless device .

Can you run lspci | grep wireless and lsusb and edit your question to include the output? – Seth Jan 7 '13 at 5:18

Check to find either the switch is turned "off" or blocked in the BIOS if not run sudo rfkill unblock alland sudo rfkill list to see what is blocking the wireless

Some have a hotkey like Fn+F2 (or something else) that will turn it on or off.

Wireless is disabled by hardware switch

I checked the BIOS , there is no settings for wireless enabling,and in my lap there is no physical switch for wireless adapter . – ubuntu_geek Jan 7 '13 at 5:12

I made the wireless adapter working in ubuntu . Login to the windows 7 (My other boot os), Then Disable and Enable the wireless adapter using "fn+f8" then boot into ubuntu then it works .I think the ubuntu driver for wireless has some drawbacks .
