I'm using Ubuntu 10.10 on an hp dv4 and my wifi was working just fine(except the wifi led blinking) till yesterday. Now when I touch the wifi button it just won't switch ON!!! :o I didn't make any changes yesterday but updated my system today.

I have no idea what happened. Any clue???

I ran the command sudo lshw and got its output as:

*-network DISABLED

The network is disabled?!? :o i tried to enable it by right clicking on network manager but the Enable wireless button has been greyed out.

I opened the file /var/lib/NetworkManager/NetworkManager.state and found that the contents are

[main] NetworkingEnabled=true WirelessEnabled=false WWANEnabled=true

I tried to change WirelessEnable=false to WirelessEnabled=true but after reboot it resumed back to the same state.

  • That stupid touch-sensitive button has got to be the worst idea ever in the history of computer case design.

Try rebooting. If it's still offline after the reboot, press the wifi button once more and restart again.

I had a similar issue with this on my dv5.
