BTW, the problem triggered today on my MR200 (first one), on channel 11, only
one iPhone.
OpenWrt configuration was typical, the only change I made was encryption
(psk2), and adding an encryption key.
all the rest comes directly from OpenWrt wifi detect feature.

I know this report is quite useless, but still.

To make reproducible testing results I would suggest to setup a channel,
(choose one that is the less used by other wireless networks),
problem may happen on some channels and not happen on other.
The 30 clients are all Apple iPads (a mixture of iPad mini and mini 2, running
iOS 9-11). During this testing period, all clients were simultaneously
downloading files from the devices’ sdcard (served via nginx running on the
device). Although this is not a typical use-case, it was useful in
stress-testing the wireless setup.
For such scenario I would suggest hardcode ba_size = 0 and see if that
would help.
I also attach another patch, can be applied on top of two previous.
This one should give RX hardware more time to provide proper BlockACK
frame, so hopefully could help with seq mismashes.
