Get Wake on LAN working on Linux with Atheros network adaptor

If you’re using an Atheros network adaptor and running Linux, you may have found that Wake on LAN (WOL) doesn’t work.

This is caused by a known bug/workaround to a previous Linux issue with Wake on LAN on Atheros network adaptors:
https://bugzilla.kernel.org/show_bug.cgi?id=61651

I’ve been monitoring this bug for some time now, but have frustrated that a permanent fix hasn’t made its way into the Linux kernel yet. I can however confirm that the latest fix on the site works, and wanted to share basic instructions for those not used to executing scripts in Linux (in my case Ubuntu).

Fix:

1. Download the latest file from the above address
2. Extract the tarball somewhere
3. Open a terminal window, and navigate to the folder you extracted the files too
4. run “sudo ./setup”
5. The install should happen

Following a reboot, I was able to use Wake on LAN.

I hope this works for you too
