Recently upgraded six RB1200 routers to v6.11. Three went from v5.26 and three went from v6.7.
Now, we experience unstable ethernet connectivity to Ubiquiti radios (NanoBridge and RocketM5). I am seeing negotiated link speed fluctuating from 100/FULL to 10/HALF to 10/FULL. Hard setting the radio and router interface to 100/FULL does not help. Radios on v5.5.6 or v.5.5.8 - both experience the problem.
When the issue occurs the port continues to show "R"unning state but any services running on the interface stop - EoIP/OSPF/RIP etc...
To fix, you need to power cycle the radio and then disable and enable the router interface. It fixes it for a random amount of time. Sometimes minutes and sometimes hours...

This problem is not occurring where we run v6.10 of RouterOS.
Is this fixed in 6.12?
