I have just made a setup with a couple of 2504 controllers and varius accespoints (LAP1142, LAP1252)
There are an open "guest" ssid with some external web authentication.
One of the users have an iphone, if he is near a LAP1142 he are having troble connecting, sometimes he get a connection, but it is painfully slow.
If he connects to a LAP1252 everything is ok.
The problem came after converting from autonome ap's
The controllers are running 220.127.116.11
I intend to upgrade to 18.104.22.168
Any ideas ?
