I have four R310 Unleashed APs in our parts department. I have them broadcasting two SSIDs. One is for internal users and the other is for guests. The internal SSID is password protected and works fine. The guest SSID requires the user to simply click through. This SSID keeps dropping the signal. Sometimes a user can connect in one part of the building but if he moves around the building the connection is dropped. I can't even get the connection to stay stable on my own phone. Both devices work fine on the other SSID. Any ideas?
