Why doesn't my laptop connect to the Wi-Fi?

So

My laptop does not connect to the WLAN although it is shown to me I also have the correct password.

And when I'm in the WLAN, he throws me out.

Check if the Wi-Fi is working properly.
Reinstall the WLAN driver.
Let an expert see about it. 😊

Maybe because there are corresponding locks entered on the router (only devices that are entered there are allowed)?

Or (if it is a public or a hotel WLAN or similar) because you first have to open a browser window to log in to the WLAN because it costs money?

So

Is not a public Wi-Fi since I live in a house with my family

Then I tap a lock.

The question is, what exactly do you mean with "And when I'm in the WLAN, he throws me out." mean.

Do you fly out of the WLAN completely after a short connection to the WLAN? Or are you connected to the WLAN, but you can't access the Internet (these are two different things)?

Either someone has set up a lock for your device (e.g. Depending on the time of day that you can only access the Internet at certain times or the like).

Or, for security reasons, the router is generally set so that it only accepts connections from known devices (MAC addresses). Then your device in question would still have to be approved in the router so that it can use the Internet.

So

So after I'm in, he throws me out in a few minutes then the IP address can't be retrieved and if I try to register again afterwards it is only there and then I won't be able to get in unless I make a new start

Oh, hmm. Good question…

Can you log into the router (via its browser interface) and see if there's an error log somewhere in the router from the moment you tried it? Maybe there's something helpful in there.

Otherwise I have no solution.
