AP 3710i
WC 5210 v 9.21.02.0014
The site consists of 330 Aps and the behavior is observed in some of them always the same way: first, it is not possible to connect on the 2.4, next: the reboot, with the firmware update message (several cliclos)
The example below is a library served by 4 ap with 250 users at most. Bandwidth limited to 2 Mb per connection.
Any idea?
