A number of times now I have seen an issue where for some unknown reason, the AP TX rate on a force 425 link will drop and “stick” at some arbitrarily low rate. An example from today is that I logged into one of the links and noticed the AP TX rate was stuck at SS5. Last week on a different link, the AP TX rate was stuck at SS0. On both of these links the channel in use is quite clean, according to the spectrum analyzer.
The “fix” is to kick the station and when it re-associates, the rates resume at their normal high numbers for some time. In the case of these two links that would be DS9 in both directions on one, and DS11 in both directions on the other.
Is this behavior one that has been addressed by AXG-4475 in the new beta? All of my links are running 5.1.3 currently.

Last 6 hours of same link. You can see when I kicked the station and it came back:
