I have an AEBS that runs 2 network, one for our laptops (all Mac) and one for our iPhones. Recently (maybe after upgrading the FW) I can´t connect any iPhone 2G, 3G or 4 to our Wifi. They see the network (sometimes), but are asked for password. I get the message wrong password or unable to connect to network. The password is correct (they used to join automatically) so what is wrong?
