MKR 1010 not connecting to WiFi

Hi,
I have bought an Arduino MKR 1010, after trying to deal with wires connections between a Nano and ESP-01 and difficult communications between them, hoping that all the problems would have been solved with a brand new Arduino MKR 1010.
Unfortunately not. Now I am battling with other types of weird problems. My board doesn't connect to the home WiFi network.
I have updated the firmware using the procedure suggested in a post in this forum. I loaded and run the firmwareUpdater sketch, then I used the WiFiNINA updater tool. At the end I had a message saying "Passed".
I then used the CheckFirmwareVersion Sketch, and it says my firmware version is 1.3.
My Arduino IDE version is 1.8.12, running on Windows 10.

Using the ScanNetwork Sketch (both ScanNetwork and ScanNetworkAdvanced) of the WiFiNINA examples it first says that there are 0 networks found and later it says "Couldn't get a WiFi connection".

The WiFi network does exist and is working, because it is used with the computer where Arduino is installed.

What else can I do to solve the problem before I think the board is faulty and return it back to Amazon?

Thanks for any help
