About WIFI
Get an Android device and install the Meural Application from the play store
( https://play.google.com/store/apps/details?id=com.meural.Meural )

Wifi network, the frame will open it 30 seconds after boot. You can see the name
and the connection status on the Frame screen

connection (pollok79 in the image below)
