Right, in business ... took an effort but there we are.

Still couldnt get any info from "find /sys -name rc_stats". However, I
found an old thread from last year which interestingly seems exactly th=
e
problem.

So have done similar and mounted debugfs at /debug. This is the results=
 of
cat /debug/ieee80211/phy0/stations/f6cefa14/rc_stats:

Let me know if this means anything or you need further info. Certainly,
seems to confirm that connection never seems to go above 11Mb/s.
