Hmm.. From my experience too strong signal can degrade performance
with qca988x. You could try reducing it via `iw`. You could also try
checking if using only 2 spatial streams also yields problems with
MCS8 and MCS9.

Antenna themselves might be the problem as well. Strong signal doesn't
mean good signal quality. If your antenna connector is damaged or
antenna is of poor quality you might end up not being able to use
highest MCS rates.
