I can connect to my Wi-Fi on my Mac and my mobile phone. Only on my laptop can I find the WLAN under networks, but if I want to connect to it, I get the message: "No connection to the network possible".
I have already deleted the saved WLAN profiles under Command Prompt. I have already restarted my PC. I already have the WLAN disconnected and reconnected (also plus ignore and enter new password). I also restarted my router, this helped, but the same problem recurred the next day. And as I said, this problem only exists if I want to connect to the Wi-Fi on my laptop. Everything works fine on Mac, mobile phone and the devices of my roommates.
Maybe your router doesn't allow new connections.
Look in the settings.
At once? Before that it was always on my laptop. New cell phones from friends can also connect to my Wi-Fi. And after restarting the router, it also works.
Then it's because of the router. Maybe your dhcp stack is too small?
is the number of dial-ins too small?
Is there Windows 10 on the laptop? Then check to see what status you are on and whether there are any Windows updates to install. Some time ago there was a Windows update that created exactly these annoying WLAN connection problems.
