Yesterday I upgraded my Ubuntu Natty to Oneiric on my notebook HP G61 (wifi card Atheros ar9285). When I start on normal mode wifi dont work: menu under tray-icon says; "Wifi hardware switched off".

If I put the command "rfkill list" I get this answer:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

then I launch "sudo rfkill unblock all" but the output of "rfkill list" dont change.

So when I start on recovery mode wifi work normally. This is the output of "rfkill list":

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: hp-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Any suggestion?

The message hard blocked: yes, means that there is a hardware switch that is switching off the wireless adapter.

Do you have to use a Fn+key combination to switch on wireless? Are you dual booting with another operating system and have you switched off wireless in that operating system? The windows operating system has the ability to switch off the wireless hardware and Ubuntu/Linux does not have to ability to over-ride that action.

Try (with your laptop off) removing the battery and the power cable and then press the power switch for about 30 seconds. When you're done, put all things (battery, power cable) back and then switch on your laptop again. Check if your wireless is back from the dead. It was the only thing that worked for me.
