I bought Pi 4 Model B recently from an official seller.
Then I installed
raspberry pi OS 32 bit as it was mentioned on site.
I completed the installation setup and everything was working fine! Wi-Fi was working fine too..
After 3 days when I turned it back on surprisingly it was not connecting to my network through Wi-Fi!
I could not figure out why this was happening so I reinstalled the OS and now during setup I get this message while connecting to WIFI:
Failed to connect to Network
I double checked password for my router, everything matches.
Here's an update to this issue
After disconnecting the Wi-Fi adapter surprisingly the onboard Wi-Fi picks up the already connected network. I rechecked by rebooting the Pi multiple times and it is working fine now!
It worked fine for sometimes! NOW it's not working!!
