Why does Briefcase say there is no WiFi network when there is one?
Double check that the WiFi symbol is visible in the status bar of your iPhone when you are running Briefcase. If it is not, you can join a WiFi network from the “WiFi” section of the “Settings” app on your iPhone. If you continue to have difficulties, it sometimes helps to turn WiFi off and then on again in the “WiFi” section of the “Settings” app on your iPhone.
