Internet denied?

I haven't been able to connect to my Wi-Fi for 2 days and have to use my neighbour's Wi-Fi.

When I try to connect to the WLAN, the Internet connection is usually refused or could not be connected to the network.

Can someone help me?

You mean your Wi-Fi

then restart your router.

and I didn't even know that you were connected to THE Internet, I connect to either THE WLan or 4G and then the internet runs over it

When I try to connect to the WLAN, the Internet connection is usually refused or could not be connected to the network.

"Most of the time" means exactly? Is that a message from the system or from the browser? The message "Internet connection refused" is completely unknown to me. Literal error messages help. The error messages you mentioned say two completely different things.

Delete the WLAN profile on your phone and reconnect to the WLAN.
