I have an Access Point that is connected to a router. The router has a WEP key, but the Access Point is unsecured. Also, for some reason when I try to enter the gateway of the Access Point the web browser displays nothing. Is there a way to put it a WEP, WPA or any other type of security to this unsecure network without entering its gateway? If it is important, I have access to both a Mac and a PC.
