I believe that it can happen if no one is connected to that AP. AFAIK some AP give you the chance to connect using the AP Mac Address. Is the network WEP / WPA protected?
I'm running R158 on a MacBook in passive mode using the built in Airport Express, but I am not able to see any connected clients. The only client listed is the AP itself. Have I missed somthing?
