Arduino Uno Wifi Rev.2 verbindet sich nicht mit dem Internet?

Ich versuche meinen Arduino Uno Wifi Rev.2 mit dem WLAN zu verbinden. Der Code (Beispiel Code WiFi Nina ConnectWithWPA) lässt sich kompilieren und hochladen, keine Fehlermeldung. Alle "Werte" (Passwort, SSID) stimmen. Der Arduino hat die neuste Firmware. Wenn das Programm dann aber hochgeladen ist, entsteht eine Endlosschleife, in der der Arduino immer wieder "Attempting to connect to WPA SSID: XXXXXX" ausgibt, er sich aber nicht mit dem WLAN verbindet, da er sonst "You´re connected with the network" ausgeben würde.

Danke schonmal für eure Hilfe

Mein Code:
/*
 This example connects to an unencrypted WiFi network.
 Then it prints the MAC address of the WiFi module,
 the IP address obtained, and other network details.
