i have client at 5500MHz,signal is -59db, 3x per day is TCP/IP communication between two sides dead.If i disable/enable CM9 on client side,so all works fine. In 2.9.13 and previous version is not this problem !!!
please make the support output file before disabling the interface and send it to support@mikrotik.com.
Also have you checked the periodical-calibration setting.
Dear uldis, Periodic calibration is on 01:00:00 and DEFAULT.
Our routers show 60s as default. Maybe it was a number from an older router that was upgraded. A new install should have 60s as default.

problem was solved: this feature is manualy DISABLED and all works fine, now i test 2.9.16:)
