I'm having the same troubles, tried with two different MT7621 device, ZBT-WG3526 and SK-WB8.

The problem happens to me several times per day if I've SQM activated. Tested with Lede 17.01.0, 17.01.1 and 17.01.2.

I've tried also disabling the WiFi interfaces, no difference.

Of course the 2.4 WiFi has its own problems ... but I believe they are not related to SQM.
