Got the same problem, but with a different network controller.
Worked fine under 10.10. After upgrade i could not activate WLAN like Michael

As you can see in the duplicate Bugreport 791373 you can fix it with blacklisting acer_wmi in the /etc/modprobe.d/blacklist.conf

This is a nice and simple workaround. I tried it 5 minutes ago and it works. All FN key combinations work properly.

same here.
 it's a kernel problem, we're trying to fix it here:

compiling acer-wmi.c from in 3.0's tree solves temporarily.

sbraz, this bug is still present for you in Oneiric? For me on the same laptop it's already fixed.

Michael, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 2012.
Please see this document for currently supported Ubuntu releases:

We were wondering if this is still an issue in a supported release? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://www.ubuntu.com/download/desktop .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:

If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.
