How to connect a computer via WiFi through RJ-45 input?

Hello, tell me what is the name of the equipment for connecting from an access point (Wi-Fi router) to a device via an Ethernet port? I heard something about receivers and transmitters through 220v networks plugged into a socket, does the RJ-45 receiver have an output?
Why is it needed? USB receivers do not start, pci and m2 are not in the near future. The router is far away, pulling the cable through the whole house is bad. You need some kind of thing that in the room with the PC will catch Wi-Fi from the router and transfer it to the PC via the ethernet port. Tell me what are the names of such devices for searching in stores.
Thanks

A wireless access point is
the same Wi-Fi router, only a little simpler and cheaper.
Almost all Wi-Fi routers have a "Wireless Access Point" mode of operation.

Yes, there are such devices = called PowerLine Ethernet, but they have some limitations there. The signal does not pass through network filters, transformers, uninterruptible power supplies, does not jump from phase to phase (if a three-phase connection).
And so, yes - you stick it into the socket and into the computer via twisted pair cable (RJ-45).
Here, choose any - https://www.onlinetrade.ru/catalogue/setevye_adapt...

Almost any linux-based consumer device that can have wifi and ethernet at the hardware level can do this (there is a chance that there will not be such a button in the interface, but it will most likely be possible to configure this through the console).
I set up a cheap wifi webcam (it seems like dlink or tplink then still cost 1500 rubles) in 'network bridge' mode, combining wifi and erthernet into one network, and used it to connect the computer to the wifi network
