Arduino IDE 1.8.5 Arduino Board Wifi MKR 1010 Windows 7 / 64 bit
I try to rebuild the project "Telegram Bot with Arduino MKR WiFi 1010" by AppsByDavideV (you can find it on hackster.io).
Unfortunately I can not get it run, because my board does not connect to my WIFI network: 1.) Attempting to connect to WPA SSID: X XXXXXX no success. 2.) WIFI is WPA2, as commonly used and there is a space within the SSID name, but I have also tried a network w/o a space in the SSID name. 3.) SSID and PASSWORD are correctly entered in the code (I checked it often!) - enclosed by double quotes. 4.) When I run the WifiNINA / ScanNetworks example, all visible networks are shown 5.) When I run the WifiNINA / ConnectWithWPA example, it attempts to connect, but no success. 6.) When I upload any sketch I get the error messages "SAM-BA operation failed" and "An error occured while uploading the sketch" and "Verify successful" at the same time and the program seems to work. 7.) status = WiFi.begin(ssid, password); returns 1, sometimes 6 for a moment, sometimes 4. 8.) It connects sometimes, when I restart the Wifi.

Thank you in advance for any suggestions which could heal the problem!
