Have you any idea what is’t wrong ?
ROS 5.20

NStreme and 802.11n MIMO don’t play along to well. Try increasing framer limit (http://forum.mikrotik.com/t/nv2-multilink-problem/60353/1) or do what karlos suggested: http://forum.mikrotik.com/t/nv2-multilink-problem/60353/1

Basically, run 802.11n in SISO with NStreme.

The third solution is to run NV2 instead of NStreme at the cost of higher latency.

you check the chain1, it seem abnormal.
