WiFi Status: Should be whatever network the iFly is connected to.
WiFi Network: Should be all the networks that your iFly will attempt to connect to. This includes networks you have, at one time or another connected to (Those with a (Pre)), as well as any that are within range.
If Stratux is not in the WiFi Status box, and you can find it in the WiFi Network list, touch it and iFly should attempt to connect.
Once you're on the correct network, "X" out of the WiFi Network Setup, "X" out of the Settings Page, Touch iFly GPS (Upper Left).
You should now be back at the iFly navigation screen.
