200.19.7.11.283 Chromebook Issues

[gritech]

Has anyone else tried 200.19.7.11.283 with Chromebooks?  I have ~200 of them and all that I observed had trouble staying connected for more than a minute or so.  Reverted to 200.17.7.0.152 and all is well again.  Windows, Mac, and iOS devices were fine.

Yes, Wifi6/7 is enabled.  I can try upgrading again this weekend and test.

Thanks, that would be really great. Will wait for your testing results.

I'm not sure if it helps but I did test with Wifi6/7 enabled and disabled. Same results with Android 16, neither option worked. 

I also tried disabling WPA3 (WPA2/WPA3 mixed) and only enabling WPA2, which also did not help.

Here are the results of the testing I did today
Dell Chromebook 3100 145.0.7632.165

Client is an Intel WiFi 5 / AC radio.

All APs R350

Without changing anything after upgrading (6/7 on):
Disconnecting frequently.
Open client's mac in diagnostics:
It stays connected fine!
disconnect/ reconnect at client - fine
reboot AP client is on - fine
reboot system (remote_ap_cli -A "reboot") - back to frequent disconnects.

Turn 6/7 off and reboot system
Client is stable.
Turn 6/7 back on:
Client briefly disconnects as expected, then is stable!

Reboot system:
client is stable

All this is weird! Maybe toggling 6/7 off-on changed something? But I don't dare leave 200.19 running when users return Monday after how it went last Monday.
