The installation of the video doorphone was unsuccessful, and you are blocked by the message: "This Wi-Fi network was not found".
Make sure the video doorphone is positioned not too far from the Internet Box (or Wi-Fi router).
WPA2-PSK (AES) is the recommended security setting
If you don't know how to set your WiFi router contact your internet provider.
If there are many Wi-Fi networks around your home, the channel used by your Internet Box may be overloaded. You may need to change the Wi-Fi channel in the settings of your Internet Box (or Wi-Fi router). We recommend that you first change your Wi-Fi channel to automatic, if it is not currently set that way. If this doesn't fix the problem, we recommend checking the Wi-Fi environment. You can use a free channel analysis app or a software program.
