Hi Support Team:
I meet same issue like this.The situation was not connected to iap205 when users number over 30.
That was happend 2 days ago that have a lot customer visit.
This site have two IAP205 and a radius server on lan.
DHCP server own class c ip to assignment.
Because radius server only charge for employee user authentication.
Do i enable the dynamic radius proxy?
Please refer attached file of dump.
