j: Unfortunately I don't know where would be up-to-date and correct
instructions for easily building own patched kernel, cleanly and as a
.deb packge. https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel looks
relatively simple compared to other pages, but not really sure if it's
completely accurate.

For compiling the kernel on your own, the idea would be to apply the
patch to the kernel with:

patch -p1 < v2-ath9k-Add-custom-parameters-for-CUS198.patch

inside the kernel sources directory. Then compile and install the kernel
and test WLAN after rebooting into the new kernel.

If not wanting to test the patch alone and just wanting to have the
problem fixed, I posted instructions on updating only the driver at
