I have a cluster with 115 APs, mostly 225s, and a few outdoor 275 and 277s on firmware 8.3.0.16. This is a school environment, and this school year, only in this school, I am randomly having classrooms dropping wireless and can't reconnect. The student chromebooks start spinning trying to connect to the wireless network. I have had teachers on laptops look connected, but get no internet, but can still get to random sites such as Youtube.
At times, if I walk in the room, my phone and device will not connect, other times I can, all while the student chromebooks still not connecting. If I take the chromebook to another room down the hall, it will connect.
I have had an open ticket with TAC, and all the logs they see, the network looks good to them. We have run looked at the Cisco switches for DDoS attacks potentially, or just spikes in network traffic, but everything looks good on that end as well. Wired devices are unaffected.
Anyone have similar issues?
Thanks,
Gil
