I had the same problem. My wireless option was grayed out in network manager.

This is not invented by me, but credited to answers from others in the web. Thanks to them.

Initial problem:

Bought new Sony Vaio E Series. Installing using CD, Ubuntu 12.04. During installation wireless worked. After reboot NO!. Can not enable wireless.

I found there:

rfkill list all

rfkill unblock all

rfkill list all, works, and show: soft blocking in 'acer-wireless: Wireless LAN, soft blocked: yes'

rfkill unblock all does not manage to change. After another rfkill list all, same status remains.

Then I learned from rfkill list - How to unblock?. Thanks, Leckensteyn.

sudo modprobe -r acer_wmi

It works. Wireless Networks works 'normal' as it should be.

Thanks everybody.
