whenever I disconnect and reconnect to wifi it just shows network authentication error and doesn't connect to the wifi anymore unless I open the troubleshooter ,not even after restart it starts to work..
I assume the problem seems to occur after Big Sur for Sure because I haven't faced this in Catalina or Mojave ...
what would help me fix this up and how am I gonna do it ?
Remove " Remember this Network " then remove the connection in System Preferences >> Network. Restart the computer and Add that Wifi Connection back and test.
If the Wifi hiding the SSID or is it visible ?

Thanks for reaching out to Apple Support Communities, manmathan176.
We would be happy to help assist with the difficulties you're having connecting your Mac to Wi-Fi. Can you tell us if you are on the most updated version of Big Sur? We'll want to be sure that your Mac is completely up to date with the latest software version. The following article can help walk you through the steps for that if needed.
How to update the software on your Mac
We can also have you try booting your Mac into safe mode and see if you notice the same behavior there as well. Safe mode prevents your Mac from loading certain software while starting up so this will help tell us if something on your Mac is interfering with your ability to connect to Wi-Fi. The article below will walk you through the process of how to boot your Mac into safe mode. Once your Mac is in safe mode, go ahead and try to disconnect from your Wi-Fi source and see if you receive the same error when trying to reconnect,

Let us know if this helps.
I tried both the solutions ,my Mac is running in latest macOS big Sur 11.4 as of June 24th.
coming to the second solution which is safe mode booting ,I tried it as well ,unfortunately the problem continue to persist even in safe mode.
According to my knowledge this issue was was first noticed in beta version of Big Sur when it was first available, but currently I am using a non beta version yet it continue to persist.
I have attached how to problem looks like when connecting to another SSID. it shows wrong password even if I entered the correct one
thanks Philips for your support , this solved the issue.
