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

I replaced the old tp-link adapter, which does not know how to operate in the 5GHz range, with Tenda U9. Tenda pleased, confidently pulls downloads, does not cut down, picks up Wi-Fi when loading the OS instantly. But in games periodically loses packets, ping jumps. When pinging Google, the same picture - a constant loss of packets with jumps in ping. If you plug it into a neighboring usb port, then there is no loss for one minute, after which it starts again. I ated the drivers, read a bunch of tips, turned off a lot of things in win10, tried to do something on the command line, connected it via a usb extension cable, nothing helped. For comparison, the old tp-link did not allow itself this, but it cannot be compared in other parameters. I even began to wonder if the new adapter was overheating. In general, too many actions had to be done to make sure that saving is bad. For passive use a good adapter, for active use it is terrible. I checked it late in games after purchase - otherwise I would have returned it.
