I have Xubuntu 13.10 running on a Lenovo T520 laptop. Everything worked just fine, but today, when I was in the middle of a Skype call, my laptop just disconnected from Wi-Fi. And now it says
Wi-Fi is disabled by hardware switch in the networking menu.
rfkill unblock all, but with no effect:
rfkill list all still says:
phy0: Wireless LAN Soft blocked: no Hard blocked: yes
The Wi-Fi switch hotkey (Fn+F5) doesn't have any effect as well. Also I tried pressing Fn+F5 while booting the system but with no effect. I noticed that the Wi-Fi indicator LED below the screen is now always off, even on system reboot.
Can this mean that my Wi-Fi controller is damaged?
