200.19.7.11.283 Chromebook Issues

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.

I had the exact same issue with Android 16 device, but only on the main SSID / LAN. It would connect as usual, be able to browse the network for 30-60s, and then all traffic would stop. However, tagged VLANs were not affected for some reason. Downgrading back to 200.18.x.x resolved the issue.

Hi @gritech,

Can you confirm if you have Wifi6/7 enabled on the SSID under Advance >> Radio Control.
If yes, can you try disabling them and try?

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.
