WiFi not connecting - Windows 10

[Hebe]

Hi all,

I'm hoping someone can shed some light as to why my laptop does not connect to the home WiFi.

I can click on my router name and it asks for the network security key, I enter it and it says incorrect.

It will sometimes pop up the network settings box asking for the username and password.... these don't exist and aren't needed on the PC (interestingly also on Win10).

I'm getting beyond frustrated now...

Thanks in advance!
