Can you control your router remotely so that the internet is off?

So with the laptop or cell phone, I mean.

If you log on to the configuration page with the laptop or PC determined.

think there's also a page where you can issue the router or the internet connection. But I'm not sure and that will be different depending on the provider

Yes, that is possible. For example, with my router on the FritzBox side.

But you can also install a timer / smart socket and control it if necessary.

You can disconnect from your router's settings menu

As soon as you are in the LAN, this is absolutely no problem. Call up the configuration page, log in with your name and password and issue

Great. So exhibit internet ne? You can't access the Internet with a network cable, can you?

Access via LAN then no longer works, at least not with the second method, that's right. With the configuration page you can set the access for each individual device.
