I'm in need of help. I have a Sony PCG-61315L. I just downloaded ubuntu and loaded it up. I go to network and it won't let me enable wireless no matter how many times I click to turn it on. The switch on the computer to turn on wifi is definitely switched on. Any help is appreciated. The ubuntu I downloaded was 12.04.

As far as I know some Laptops use a special key combination to switch wireless facility from the keyboard. Have u switched that on ? – Ravi Raj May 31 '12 at 7:33
Which version of Ubuntu? Have you tried the Wiki help page? – david6 May 31 '12 at 7:40
I once had the propblem that wifi only worked when i booted the computer with the wifi hardware switch off. Then i had to turn the hardware switch on when the system was up. Did you try that? – serve.chilled May 31 '12 at 8:37

If the wireless is stuck as if disabled by hardware (it happens in some laptops when you use the wireless button a lot) and you cannot physically enable it, try in Terminal:

sudo rfkill unblock wifi
