We recently upgraded to 32.1.6 for most of our locations a couple of weeks ago. We have MR46 models. We have a lot of Android tablets in our environment, and it seems that version causes a ton of disconnects/reconnects for those devices. In the timeline I also saw disassociations, connections, DNS and DHCP and authentication almost every minute. On the tablet, it would disconnect from Wi-Fi and reconnect over and over again.
The client graph showed a lot of disconnects as well. I had only one location report an issue with Wi-Fi dropping and reconnecting on the Android tablets which led me to look into this. We have 68 locations and HQ. We rolled back to 31.1.8 and the graph is stable again. They've always had good signal strength, and I don't see anything interfering with the Wi-Fi.
We can't downgrade most of our other ones without getting TAC involved, so we're going to update another location that I talked to and confirmed they are experiencing the same issues to 32.2.2 to see if it helps before going the mass downgrade route. I'm also double-checking Android as well. The devices recently upgraded to Android 16 and they're all the same model tablet. My phone on Android 16 also had some of the same events on the timeline and graph as well. Android and MR upgrades happened pretty close to each other. The graph also seems to change when I refresh it, so I'm using the timeline to help troubleshoot further.
Update: The downgrade actually didn't help, devices started disassociating again about 20 minutes afterwards. The upgrade to 32.2.2 did not help either. On that one, the devices are reconnecting every 3 to 10 minutes.
