I tried switching to the 10.2.4.70.10-2 firmware version, which seems
to be the latest version I can find for QCA988X. It seemed like it was
working better (though it's hard to say as it happens sporadically),
but then the failure happened again. Are there any newer versions than
that one, or any other ideas?
