also noticed now that the noise floor changes with signal strength as

after wifi restart

iwinfo:

signal: -59dBm noise: -108dBm

then goes to

signal: -52dBm noise: -103dBm

and finally drops to

signal: -59dBm noise: -103dBm


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,
