PlayStation 4 internet error?

I have the problem that my PlayStation 4 does not receive Internet even though the router is on and I can use the router's Internet access via my smartphone

If I want to establish an internet connection between the router and my PS4, it says, server connection is not possible. There may be a problem with the manufacturer of the connection to the network, or the PlayStation Network or the server of the service provider may be temporarily overloaded '

can someone help me there?

Unplug the Playsi and plug it in again. You can also disconnect your Wi-Fi from the Playsi again and reconnect (with password, etc.)

Then I'll disconnect it from the electricity

with the Internet connection type test it fails because of the Internet connection the IP can be called up hm

P.s. I'm accidentally on. Butten, Not Help Pond "came

Settings - Network - Connect to the WLAN, click on it so that the tick disappears. Turn the Playsi off and on again. And then connect them back to a network.

Alternatively, switch router off / on.

I tried to connect my PS3 to the network hm it doesn't work well with my smartphone it works really funny
