I have a powerful modern router at the front door (I didn’t want to pull the wires, where they punched a hole, they hung it there). There are 3 reinforced concrete walls to the back room, a sliding wardrobe with all kinds of metal fittings and, among other things, a huge number of other intersecting networks. Before my room, a signal of 100 Mbps was absorbed at the output up to 1.2 - 4.5 Mbps. And sometimes even torn. I tried a bunch of whistles of this kind, but only this one saved me. As a result, the losses are no more than 15-20% The best adapter I have ever used.
