I am running dual boot Ubuntu 12.10 and Window 7 on a Sony Vaio VGN-FW31E. The wireless switch has broken and come away from the motherboard, which switches it to the permanently off state.
I have removed the mini pci express wireless card Intel 5100 series and blanked off pin 20 which switches off the card (on is low). The wireless now works fine in Windows 7 but not in Ubuntu. As I only use Windows 7 to browse one poorly designed website I would really like to get my wireless card running in Ubuntu.
rfkill list all returns the following:
0: sony-wifi: Wireless LAN Soft blocked: no Hard blocked: yes 1: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: yes 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no
