I keep having ports going from several of my Mikrotik 433s and switches going from 100-full to 100-half.
I have to switch from auto negotiation to manual. Seems to work most of the time, but even then I have found some to go back to 100-half, put back in auto, then apply, no luck, then back to manual and the unit will go back to 100-full. This is getting very annoying and getting complaints because of this. Can any of you tell me what is going on here? All of the firmware is current, but this was doing this before the updates. My switches are the crs125-24. Any input on this will be appreciated.
This behavior typically indicates an issue with your cabling. I would recommend replacing the cables on the affected ports.

Seems it was caused by another 433 going bad. I do not know why, but it would cause several of the other 433s to go in half-duplex. Another thing I have found with these units, if one starts putting out bad data, it will shut down the rest. This seems to be seen when you monitor the data rates on each customer. normally you will see a 20 to 30 kbs, then they all jump up to 200 to 500kbs. Then no more internet for customers and the phone call begin until you find which one of the APs are effecting all the rest. Anybody ever had these problems?
