I'm new to Raspberry Pi and I have to make a script based on WiFi connection, but sadly I can't use it.
I have a Raspberry Pi3 Model B+ with the NOOBS sd (the one given with the Premium Kit). I installed Buster version of both Raspbian and Raspbian Full from the recovery mode, but I had the same WiFi issue with Stretch (installed in an old attempt).
Since the installation, I can see every WiFi networks in the nearby, but once I enter the (correct) password of mine, it doesn't connect. I tried to do it with no success either with and without updating the system. I tried to connect to 2 different networks with WPA2 key with the same result, although I can connect to them with no problems from other devices.
I also set the right localisation option into the raspi-config.
I have no problems connecting to Ethernet, but I need to use WiFi. Moreover, every now and then, it connects and works, but after some minutes it disconnects by himself.
Can you please help me? Thank you
