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

during operation, the connection speed steadily cut. at a network connection speed of 100mb (on any device without tenda it gives out 90-92) with this miracle adapter it gave out from 2x to 30. that did not try above did not work. all the reviews and forums were shaken up where this adapter was discussed. only the support service saved, as it turned out such unstable work if you plug the device into USB 3.0, if you rearrange it to 2.0, then all the rules are within the margin of error.
