Sorry for bad english.
I have а problem - does not work Nstreme under ideal conditions. And the link works fine in the modes of 802.11 and NV2, mode Nstreme low ratespeed and disconnects (“extensive data loss”).
802.11 mode:

When idling increases the counter hw-frames.
The problem in different configurations:
- RB711UA-5HnD + sector antenna MIMO, CPE RB SXT 5HnD, distance 10 meter, 5 GHz
- 2 x RB433 + R52Hn + sector antenna MIMO, distance ~1000 meter, 2,4 GHz.
In the two configurations works fine 802.11 and nv2, does not work nstreme. I can not migrate to the nv2, because he does not support EAP-TLS.
How to fix the problem?
