Bug Description
For my laptop (Acer Timeline 3810t), after upgrading to 2.6.31, the RFKILL switch now defaults to on (wireless disabled) on every boot. It works if I manually turn off the switch.
The switch is a toggle switch, and it used to default to off under 2.6.30/alpha 2.
I am using the iwlagn driver. The card is an Intel 5100.
01:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100
Kernel driver in use: iwlagn
Kernel modules: iwlagn
I have tried using the RFKILL utility found here - http://
This is annoying because I need to use wifi everytime I use my laptop, and there is no programmatic way to enable it.
Thanks!

"Fixed" in 2.6.31-5!
The switch now defaults to off on every boot.
I guess it would be the best if it can somehow "remember" the state across reboots, but I'm not sure if that's possible, and for me, default to on is good :).
Thanks for the hardwork!

To me it seams that the issue is back in 2.6.31-14-generic.
wifi works only if I switch wlan off before I boot.
Otherwise rfkill list shows:
rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: yes
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
and it is than impossible to enable wlan - no wifi!.
But it works if I switch wlan off before I boot. than I can toogle the switch and >rfkill list shows allways the right state.

I think you may be seeing a different bug, and may want to report it as a separate bug. The original bug is Acer-specific (since blacklisting acer_wmi worked-around it). And I don't think the problem came back for me.
Blacklisting acer_wmi reverts this behaviour, so it is probably something related to acer_wmi.
