I installed this update [Stable Update] 2018-12-02 - Kernels, Plasma, Mesa, Cinnamon, Gnome, Deepin, XFCE, Vulkan: in Majaro - i3 edition.
This broke my WIFI: Atheros QCA 9377 firmware fail. There are lots of threads about this Adapter on here in the past, but none for this update as yet.
In this scenario: Wireless adapter recognized by
inxi, lspci, hwinfo, etc but not by
iw link and more to the point, nw-applet showing nothing available.
After a long search (I’ll spare the details unless someone wants to know) for what had changed, I determined that the update brought in firmware-6. The previous setup used firmware-5
What I did to fix was just get rid of Firmware-6.bin in the hopes the system would pick up and use 5.
sudo mv /usr/lib/firmware/ath10k/hw1.0/QCA9377/firmware-6bin /media/[USBStick] sudo reboot
After which, normal functionality was restored.
Hope this might help if someone else runs into this.
Also, please advise if there is a better or safer way of doing this (just getting rid of the offending file… ). I actually pulled the same stunt a few months ago on an AntiX system that got a new iwlwifi driver that didn’t agree.
Seems like a simpler solution than rolling back the install. But I am still a bit of a novice on hardware and firmware stuff, I would be happy to know if I am overlooking anything?
