Just reset my password to express my THANKS for this particular solution!

Spent hours thinking it was some kind of CentOS dependancy / repository / config issue, before landing on this solution.

In my case I just had the "firmware-6.bin" file to remove on an Lenovo ThinkPad E470, with the Qualcomm Atheros QCA9377 wireless adapter, and reboot.

nmtui and nmcli worked like a charm thereafter.

Code:

cd lib/firmware/ath10k/QCA9377/hw1.0/

Code:

ls

For reference I get

Code:

board-2.bin  board.bin  firmware-5.bin  firmware-6.bin  notice_ath10k_firmware-5.txt  notice_ath10k_firmware-6.txt

Remove 'firmware-6.bin' and 'notice_ath10k_firmware-6.txt', (leaving firmware-5.bin and notice_ath10k_firmware-5.txt). When you next reboot (or unload and reload the ath10k_pci module), you'll find that it loads the working API 5 firmware. (Your previous output showed it was loading the API 6 firmware.)

So

Code:

dmesg | grep -i ath10k

should show something like

Code:

ath10k_pci 0000:16:00.0: firmware ver WLAN.TF.1.0-00002-QCATFSWPZ-5 api 5 features ignore-otp crc32 c3e0d04f

and more importantly, your wifi should be working.

According to that thread, the firmware-6 files always seem to result in non-working wifi for these devices.

Hope that does the trick.

I must sign up to say thank you

I'm only surprised that it is still an issue all these months later. In any case glad to have been of help to all who came searching.
