Follow up to Ubuntu 14.04 Wireless not working: no network interface. Atheros [168c:003e] device
The devs have released the firmware (as noted in the bug report)
Now, I have the firmware installed under the answer instructions.
How do I remove that firmware and start using the official one (so that I have something more tested and I'll get updates/bugfixes in the future)?
$ dmesg | grep qca6174

I think you likely have the latest firmware – Jeremy31 Nov 15 '15 at 14:35
