want to connect satellites by wire (wifi connection not possible)

You have posted your message in the section of this community given over to General WiFi Routers (Non-Nighthawk). (This is easily done, given Netgear's complicated community structure.)

Many questions apply to different types of device, so you might get responses here, but you might get more help, and find earlier questions and answers specific to your hardware, in the appropriate section for your device. That's probably here:

Orbi - NETGEAR Communities

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware.

You may have done this already. I can't tell from your message.

I mention it because Netgear gave up on supplying paper manuals years ago and people sometimes miss the downloads.
