What to choose to increase the radius of Wi-Fi cables?

Hello. I have a 3-room apartment. In my working room is a router, from it LAN cable to the computer and cables are stretched: in the kitchen, and in the other rooms. Everywhere catches normally except the kitchen wi-fi, there is a cable with internet from the router. What should I buy to get from this cable to distribute the Internet? Thank you very much in advance!

Hello. In your case, to increase the coverage of the Wi-Fi network, it is best to choose an access point. Or almost any router that can be configured as an access point. Or switch the router to the appropriate mode of operation, if it has such a function. Set the same network name and password as on the main router.

Perhaps there are repeaters that can receive and amplify the signal not only over wi-fi, but also over the network cable. But the LAN port on the repeater is mainly for connecting devices to the Internet, not the other way around.
