Firmware seems less stable than that in linux-firmware 1.176. Getting
strange delays with the WiFi in general.
One thing I noticed was that it was better,
To clarify, higher bandwidth transfers on the radio seems to increase

Ok, I managed to get the latest firmware working. It still exhibits the
same issue. I think I must of only rebooted last time instead of
shutting down completely.
I've tried the speaker sitting on top of the track-pad, about 50 cm away
from the laptop - all to the same effect - the it's like it

/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin
board-2.bin is also required.

Skip/Stutter/Delay WiFi bandwidth conflict
@kaihengfeng I did try the latest version of the QCA6174 4.4.1 firmware
which matches the firmware in linux-firmware v176, and the result is the

/lib/firmware/ath10k/QCA6174/hw3.0 folder to test this.
