How to distribute Wi-Fi without a lan cable?

Question

Iron

A wi-fi router, d-link dir620, is driven into the wall, to which a lan cable is hooked up.
The task is to catch the Wi-Fi network in the middle of the apartment and distribute it further in the same way via Wi-Fi.
What is the best device for this? Are there any solutions besides the rose of accurate Wi-Fi repeaters? It is possible to replace the current router with another one, and, preferably, with a link to the step-by-step configuration;)

Answer 1

In general, I went along the classical path. I took 20 meters of cable from IT people at work, they dug out an unused asus rt g32 router from them, hid the cable in the baseboards and corners to the middle of the apartment and now I use Wi-Fi at normal speed without obvious losses and material costs)
I tested the repeaters, the speed did not suit me. For surfing it is enough if a couple of devices, if you turn on 5 or more and somewhere something is updated, some material is downloaded from the network, the speed drops dramatically (

Answer 2

Socket - Socket - e.g. TP Link TL PA411 or DHP-701AV

Answer 3

TPLINK - I'm sitting through a neighbor, without his knowledge,
turn on WDS, turn off DHCP and set the IP address of my router to 192.168.0.2 (if the victim's ip is 192.168.0.1) or 192.168.1.2 (if the victim's ip is 192.168.1.1)
Network names should be different. The victim's router does not require settings.
