Use LAN socket?

Halli Hello, actually this is my first question on this platform.

I don't have a really good Wi-Fi connection in my room, but I have a Landose on the wall and I thought about connecting my laptop with a LAN cable. Said and done did not work and no connection was established. Now I'm wondering whether it is even possible to connect via Landose and how it would be possible at all, or whether it is only intended for Wi-Fi routers. A LAN cable fits into the socket without any problems.

I'm also a total layman in the field, but I know that it's not the laptop because I can use it on the router with LAN.

Indeed, it looks like a LAN socket

The question is: Is it also connected with a cable and is this in turn placed in a patch field, which in turn is connected to a switch or the router or directly to the router?

You have to clarify THAT first. Otherwise we can't help you

And if your notebook has a LAN socket, you can of course also connect the notebook to the router / network using a LAN cable

Thanks for the answer.

I think I have to clarify that. I have one more question. Are Wi-Fi repeaters able to strengthen other Wi-Fi repeater signals? LG

Yes, in principle

BUT it should be noted that this is / will not be anything half or whole
You will always have problems depending on how many walls and ceilings there are in between

The best is a repeater that establishes a connection to the router with a WLAN band and then uses another WLAN band to establish a connection to the next repeater or to the end devices

That looks a lot like an ISDN box. Unscrew it and see how many veins are connected. If only 4 wires are connected, the cable must first be replaced, and a distributor must be set up at a suitable point in which all the flat cables of the house run together.
