Symptoms:
- Ipad/Iphone can't join a wireless network
- Ipad/Iphone can't roam properly
- Laptops and androids join/roam just fine
- Debugs on the Controller show the Ipad/Iphone joining
Solution:
Turn on Fast SSID switching.
The apple devices for whatever reason try to join a 2nd SSID before they receive the response from the controller. With the option disabled the WLC sets a delay before the devices and join a different SSID. The vicious cycle begins.
Nothing make people more irritated than not being able to use their shiny apples.
