Why is the SAS network no longer visible under WiFi networks?

I connected to the SAS network and entered my WiFi password.  Now I can not see it on my phone anymore. Why?

The SAS network is visible only when your device does not know how to connect to your WiFi.  Once you specify that information, for security reasons the configuration part of your device is no longer displayed. If you want to use a different WiFi network, you will need to clear your device first. See the FAQ section for your device on how to move your device to another location for detailed instructions.
