E.g. If the router only has one lan connection free but my 2 needs it, e.g. One for pc and the other for ps4. Are there such adapters without influencing the speed? Happy recommendations!
Called network switch:
Sure, take a switch and then you have no particular problems with the speed.
Then you need a switch. So not the Nintendo console but a LAN switch. You can get a simple Gigabit Ethernet switch for just 15 euro

Your PC and your Playstation have to share a cable to the router without any loss of speed. But since LAN is usually much faster than your internet connection, you will not notice anything.
How do you connect that. I only see a power cord. Is there the Internet in the line or what
With such a connection doubler you still need 2 LAN ports on the router and the speed is reduced to a tenth.
You have to securely connect it to the router, right?
On the back you have a power connector and on the front you have 5 LAN ports. You lay a lan cable from the router into the switch and then from the switch to the PC and the PS4.
Oh, then thank you
