Resolved many months ago by replacing the Mimosa POEs with UBNT POEs. I read the remark by a Mimosa Engineer that there is a hidden ground loop being revealed by doing this. If that is true I have ground loops at 14 different tower sites. Anyway, who cares, this solution worked for me with no adverse side effects. I now have very dependable links.
I have read a number of solutions since original post:
- Replace the Mimosa POEs with UBNT POEs.
- Use a Netonix Switch.
- Put a different switch in between radio and Microtik.
- Turn flow control on the radio and the Microtik.
- I’m sure there are other solutions.
I’m running every version of firmware on my links and do not believe firmware version makes a difference. I have long and short runs of Cat5e and Cat6, all shielded with EZ-RJ45 shielded connectors, does not make a difference. Most of my routers are Cisco, a few Microtiks, I ran fiber the the Microtiks because of longer runs required.
