Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi Kanwir,

I understand that Fn+F2 does not work at all, that is a known issue with Asus laptops.

But does the wifi not show as hardblocked, and work as expected with the "options asus_nb_wmi wapf=4" workaround ? I'm asking because if you need the wapf=4 workaround then I'll add a quirk for your laptop model to the upstream kernel.

Thanks & Regards,

Hans

Hi Hans, When using options asus_nb_wmi wapf=4 the WiFi works and does not show as hardblocked.

I had this same issue on an Asus K501UX with Ubuntu 15.10 freshly installed. Wifi showed hardware blocked, fn+F2 does not work so there was no obvious way to enable wifi. The same workaround fixed the problem: options asus_nb_wmi wapf=4
