I have a WLC4402 with version 4.1.185. Layer 2 security is WPA+WPA2 with AES+TKIP.
One of the SSID configured this way works fine, but in the other one, when clients roaming, they have to re-enter the username and password. This happens with Laptops working with XP and the option fast reconnect enabled. I checked the logs but none appears related with authentication. How can I solve this?
I am thinking to make an upgrade but there is also ToIP and works fine...
