Review on Tenda U9 11AC USB Wifi Adapter - Dual Band 2.4/5G AC650 Wireless Network Card, Windows Compatible and Compact in Black by Bujang'e Lor Nganim ᠌

Found a funny phenomenon, perhaps someone will be useful. Connect the adapter to the USB socket on the front of the computer. The connection speed with the case open is 433 Mbps, with the case closed - 390. I thought about it :) I assumed that the USB cable going from the motherboard to the internal connector on the front wall can work as an antenna. Although what kind of antenna is there - without coordination, at 5 GHz . But nevertheless. I connected the adapter to the connector on the back wall. The speed dropped to 260 Mbit / s (the case is closed, and even with this connection, the adapter is shielded by the computer case). I reconnected it to the connector on the same back wall, but through a half-meter USB extension cable. The result is a stable 433 Mbps :). Just in case: I don’t write comments on my reviews as a matter of principle, I don’t answer questions, I don’t enter into discussions. Any third-party comments on my review, signed by my nickname, I propose to consider a priori "Creativity of the mentally ill" ((C) A. and B. Strugatsky, "Monday begins on Saturday"), since I already had a chance to encounter similar things on amazon.
