Comment 26 for bug 857297

Thanks, Graham. When acer_wmi is not loaded, is there a hotkey or physical button that works to enable and disable wireless, bluetooth, or cellular data connection (whichever of these your machine actually has)? Please check for this, then try the steps below.

Download the acer_ec.pl script:

  http://people.canonical.com/~sforshee/lp857297/acer_ec.pl

Now run acer_ec.pl using the following command. Note that there's a potential that the script could lock up your computer; if it does you'll just have to force shutdown the machine.

  sudo perl acer_ec.pl regs > regs1.txt

If you have a button or switch that can successfully enable/disable one of your wireless devices, you should toggle them one at a time, running the same command as above after each toggle (but changing the number in the file name). When you are done, please attach all the files here and tell me the state of the wireless devices represented in each file. Thanks!
