AP may incorrectly log client roams as authentication failures (Wi-Fi 5 Wave 2 MRs/Wi-Fi 6 MRs)

Now this would explain why I'm still getting lots of authentication failures. Will certainly upgrade this evening.

@AnythingHosted 4 networks already upgraded, 35/39 APs on 28.3, 4/39 on 26.8.2.  I'll be monitoring today to see how the fixes perform.

Out of the 35; 33 are WiFi 5 wave 2 and 2 are WiFi 6.

I still seem to get a lot with my phone this morning. The SSID is WPA 2 - WPA3 transition mode.
