To switch off WiFi :
- Click 8 times in a row on the screen in the same place
- Press "yes" to open the WiFi menu
- Click on the WiFi network where it says "connected" below
- Then select "delete" or "forget".
The frame will no longer connect to the network you deleted. It will then work in 4G (provided that you have subscribed to a subscription, after the 3 months offered).
If you want to connect to another WiFi network, select it and enter the WiFi password. If the message "authentication error" or "authentication problem" appears, the password is wrong.
