Almost everything dead even with Wi-Fi (S9 +)?

I have a problem with my S9+. Although I'm connected to the WLAN (it shows "Connected"), I can hardly do anything. YouTube and Netflix go. Otherwise nothing works. No snaps are loaded. No PlayStore. No Instagram.
Only when I turn off the WLAN and turn on mobile data does it work again.
I have the latest software update. Have restarted the device several times. Cache cleared. Everything. Nothing helps.

Restart the router, sometimes it helps.

Right. I forgot to mention. I've done it several times. Without success

Sorry, then I don't know what to do

Restarting the router is nonsense.
Either the error is clearly due to your device or the router does not let you access certain pages.

If it affects multiple devices, then your ISP should be behind it.
So what can z. B. If there are problems with the DNS server.

The problem only occurs with my cell phone. Everything is going great on my PC
