At our school, our users are complaining about trouble staying on the wifi. Often changing SSIDs or laptop's Wifi off / on will help get them reconnected. Some background: vSZ Essentials 22.214.171.124.169 We have 52 R600's, and a flat network topology. We have up to 1000 users peak. Half iPads, a quarter Macbooks, the rest Windows or Android.
In the logs I often see entries like this:
Client connection timed out
Client [dsc] disconnected from WLAN [JMCstaff] on AP [ELC 203@D4:68:4D:22:CB:E0] due to inactivity.
Client authorization successfully
Client [dsc] of WLAN [JMCstaff] from AP [ELC 203@D4:68:4D:22:CB:E0] was authorized.
The client connects, then gets disconnected due to inactivity 58 seconds later?
We are doing radius auth on the staff and student SSIDs to a Windows 2016 NPS
More looking at the AP log, there is a client timeout after 8 seconds?
This problem has been happening for months if not years, and had survived across updates to the vSZ, both software and hardware. The hardware is a modern processor with plenty of RAM running on vmWare on an SSD.
Where to go next?
