I have 14 1240s in a new building on campus. They are all powered by 3560G PoE switches. They all broadcase the same SSID and run the same vlan. Recently they quit showing the vlan and SSID in the configuration. I can still connect to the network and get an IP address from dhcp for that subnet but if I try to add the vlan back into the configuration I get the message "a vlan can not be created if a radio is not installed". These are dual radio aps but I am only using g. Would someone have an Idea what might be going on?
