The problem with debugging this sort of stuff is that you need an RF scope
to determine whether signal power of transmitter is changing or receiver
is reporting stuff weirdly.

If you are comparing against ath9k, probably you need to force your ath10k station to do /n only
(or change your AP to do /n only) so that you can be comparing similar MCS rates.

Thanks,
Ben
