unbalanced asymmetrical ccq in ptp link

I’m wandering if I am the only one experimenting
asymmetrical ccq values in ptp links…
Band: 5GHz-A/N
Package: wireless-nv2 ver.4.16
Nstream enabled.
Good symmetrical signal strenght -55/-56
Strange asymmetrical ccq: 18/97%
That make a strange asymmetrical throughput 8000/100000 kbps
The problem exists in every frequency I try.
I will try to investigate the issue in the next days.

be shure to check ccq when tx/rx traffic is esthablished.

Yes, I’m checking CCQ during btest.
What I realized today:
sending from A to B >90% ccq
sending from B to A <10% ccq
In A I have a working Motorola ptp installed in the same pole (2mt distance)
It is working on a completely different frequency (5400 against 5700)
but as soon as the Motorola tx increase my ccq go bad…
