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
[   14.926504] ath10k_pci 0000:03:00.0: qca6174 hw2.1 (0x05010000, 0x003405ff, 168c:003e:11ad:0804 fallback) fw rome-hw2.1-v211-michalk api 2 htt 3.0 wmi 4 cal otp max_sta 32

Since you installed from an Ubuntu deb file you don't have to do anything. When Ubuntu finds a newer version of linux-firmware it will be installed when you do updates

First of all, you have installed an official linux-firmware package from an official Ubuntu repository. But you installed a version for Ubuntu 15.10.

It did not install automatically, because the Atheros new firmware is available only for Ubuntu 15.10 (wily) at the moment.

Version numbers for linux-firmware for different Ubuntu releases differ. That is why this firmware package will never be replaced by anything in Ubuntu 14.04.

But I do not see any reason to worry about that.

If you really want to bother about that, you can track if that new Atheros firmware gets into Ubuntu 14.04 linux-firmware package and when it does (if ever) you can remove that package and install a native one for 14.04.

But I can't imagine why that may be ever needed.
