Im using Linux Mint 13. Wireless has always worked fine but stopped yesterday after I connected to the internet via an ethernet cable. After I disconect the cable I cannot connect to Wifi. In bottom right menu it just says "wireless" is disabled. I have tried hitting Fn F8 to no avail. I ran:
sudo rfkill list
0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no sudo rfkill unblock 0 sudo rfkill list
0: phy0: Wireless LAN Soft blocked: no Hard blocked: no sudo service networking start
The contents of /etc/network/interfaces is
auto lo iface lo inet loopback
Any ideas what I can do?
