Wireless button not working in Ubuntu/Compaq Presario CQ62

[Saman]

This was a confusing problem. Whenever I press the Wireless button to enable the wireless network, it stays orange (which should changed to blue if it is enabled). I was told that it could be most probably the wireless driver is hard locked by BIOS, etc... I finally found the solution for this.

Type this command in the command window to change the rfkill state of the wireless chipset.

Code: Select all

rfkill unblock all

Enjoy!
