Comment 10 for bug 668234

Sorry, forget my last post.
In the past, I used the following command "echo 'options acer_wmi wireless=1' | sudo tee /etc/modprobe.d/acer-wmi.conf" to "tweak" the acer-wmi module. However, this additional configuration file only prevents the acer-wmi module from being loaded according to the error message:

"FATAL: Error inserting acer_wmi (/lib/modules/2.6.38-8-generic/kernel/drivers/platform/x86/acer-wmi.ko): Unknown symbol in module, or unknown parameter (see dmesg)"

and in dmesg I have:

"acer_wmi: Unknown parameter `wireless’ "

So, I deleted this nonsense configuration file and tried the two kernels again.

"uname -rv" --> "2.6.38-12-generic-pae #51lp836865 SMP [...]"
acer-wmi is loaded (!), both in Ubuntu Natty and Oneiric --> wlan impossible

"uname -rv" --> "3.0.0-12-generic #20-Ubuntu SMP [...]" (Ubuntu oneiric kernel)
acer-wmi is loaded too, wlan not working even after unloading acer-wmi. Only blacklisting and rebooting helps

My conclusion is, that your kernel does not improve the situation :-(
Any hints?
