We have a WLC4402 running 22.214.171.124 code and 1142N AP's . We have Private and Guest WLAN's configured on the controller . We had been having wierd issues with Guest WLAN . It looks like when a client machine(Mac or Windows) tries to connect to guest wireless , they do get the right ip address but not getting the authentication page . When they disconnect or disable wireless and reconnect again they get both the ip address and the authentication login page . Not sure what the issue is but this happens on both Windows and Mac machines . Did anyone come across a similar issue with the WLC code we are running ?
