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.

sudo modprobe -r acer_wmi

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

Thanks everybody.
