Lenovo E330 Wifi is disabled by hardware switch Ubuntu 14.04

[Filip]

I have Lenovo ThinkPad Edge E330. I run on Ubuntu 14.04. Laptop was connected to thw Wifi and was on AC without battery. When I put battery in, unpluged AC and opend laptop, my wifi stoped working. It says: Wifi is disabled by hardware switch. The trouble is that this model does not have any hardware switch on its body. I have tried many things:
- Loaded default settings in BIOS
- reinstall Ubuntu completely
- rfkill unblock all does not have efect

Thank You for help

ubuntu-friendly no longer exists, thus marking that task invalid.

This is not related to the linux-wlan-ng package. Actually, make sure you have linux-wlan-ng purged (uninstalled including configuration files).
