Laptop no connection to the network why?

I have several laptops. I was not yet connected to the Internet with a laptop. So I entered the WLAN key. But get no connection. Since it shows no internet, secured. What to do?

I guess in the blue, the Läppie is older and does not go to the 5GHz WLAN? Then take the other channel.

There's n button on the router, you have to press it beforehand and then it will work with the connection, this is for security reasons if someone knows the Wi-Fi password and wants to log in from outside abusive.

Click on connect, I had that game for a week. Then I deleted the Wi-Fi connection and set it up then it was quiet.

Nope, then he will not connect to the Wi-Fi because he can't find it.

Here is a link to see if you can find it. With Chip.de I have mostly been able to restore everything

Good luck to you Sky… 🌟🌟🌟
