I have the problem that my LAN cable is too short and my PC can't receive Wi-Fi, my laptop but it would work if I connect the Lan cable to the laptop and the PC to the Internet to "transfer"?
The pragmatic solution would be a longer LAN cable or if a socket is closer than the router, you can try DLAN. That's how I solved it at my house. I had genu the same problem as you. Only bought a longer cable and then networked with DLAN later. The longer cable was then used in the living room for a new Smart TV.
That's fine. Is also quite easy to set up.
You could take a cell phone instead of a laptop.
If the Internet properties "share" on the laptop to "allow other users on the network to use the Internet of this PC", it might work.
