Finally found the best solution for myself. I tried 2 repeaters (China and Tp-link) and one router (Netis) with 5dBi antenna gain as a repeater. Nothing helped to achieve a reliable signal in the kitchen in a 3-room apartment, where the router is in the farthest room. I always knew about powerline technology, but I didn’t buy these devices, since the room where the router is installed is connected separately from the electrical panel and I was not ready to make an additional outlet at the entrance to the apartment from the cable leading to this room. But when there were no other options left, I bought this kit, but before making an outlet, I decided to still try to plug the receiver into the kitchen and lo and behold, it all worked! The technology is amazing! The only difficulty was that when I tried different sockets in the apartment, the device did not always quickly connect to the network, and at first I was upset when, after waiting 30 seconds, speedtest reported connection problems. But as it turned out, sometimes you need to wait in the region of 2 minutes.
