1. Yes, it works wirelessly, it is not at all necessary to connect patch cords to the router (this is important so as not to drill holes in the walls or throw a "temporary house"). 2. It is very easy to configure via the web interface (I did not manage to configure via WPS, but this option is supported). 3. Really enhances the wi-fi signal and coverage area (tested in the apartment). Where the router "didn't finish" before and it was "near zero" now there are 4 out of 5 divisions and ~ 30Mbps (min. ~ 10Mbps). 4. After pre-setting, it is enough to include in any email. an outlet in an apartment where there is wifi and the coverage area of \u200b\u200bthe router, but it is advisable to put it in the interval from the router to the "dead zone". 5. There were problems with a single SSID, in terms of the fact that you come to the router (where the maximum speed is), and the device still "clings" to the repeater, because of this, the speed becomes lower than the max. possible. 6. Based on paragraph 5, I set other SSIDs on the repeaters (####-ext01, ####-ext02, and saved the password for them on client devices (it is the same as for the main network), it became possible to independently switch to the desired access point if necessary. On the one hand, this is inconvenient (because additional manipulations are required), but on the other hand, you yourself can choose a faster connection point depending on your current location. For now, leave it like that. In any case, the task (unstable / weak wifi in the "far" room) is solved using these devices without additional. wires, I recommend!
