Hi, My only suggestion is to try the candalatech 10.1 firmware for QCA9880/Peregrine chips and see if it behaves better. There are a bunch of unresolved issues in the 10.2 firmware which I think Ben has fixed in his 10.1 firmware.
If it works in Ben's firmware release then you maybe can work with him to trial previous versions of his firmware to try and narrow down when the fix was introduced.
