Hello.

I have been using the .deb file for a few months on 15.04 and everything
was working great.

I just updated to 15.10 Wily and unfortunately this broke wifi once
again...

I tried doing 'sudo rm -rf /lib/firmware/ath10k' and then pasting in the
ath10k folder from the github repo you have pinned at the top of this
page but that did not help.

I tried deleting the /lib/firmware/ath10k/ folder completely and then
running 'dmesg | grep ath10k' which returned something weird:

$ dmesg | grep ath10k

Then, I tried uninstalling the .deb file and reinstalling it but I got the 
following:

$ sudo dpkg --install /media/data/ath10k-dkms_1.1_all.deb 
Selecting previously unselected package ath10k-dkms.

And here is some more info

$ iwconfig

lo        no wireless extensions.


$ uname -a

It looks like something is wrong... I can see in dmesg that it's
referring to files that do not exist in the ath10k folder.

Thanks for your work so far Adam and I hope you can provide some help
with the new Ubuntu.
