Review on 🔌 TP-Link Archer T3U Plus USB WiFi Adapter - Dual Band Network Adapter for Desktop PC with High Gain Antenna, AC1300Mbps Speed, MU-MIMO, Windows 10/8.1/8/7/XP, Mac OS 10.9-10.15 - Black by Michael Baek ᠌

After small dances with a tambourine, I achieved stable operation of the adapter. There are a number of nuances, like many here, at first there were many problems, wifi fell off, it was unstable, the speed was cut . Thankfully I read the reviews In order: If your computer (laptop) does not have USB 3.0 or higher, then this adapter will be of little use . I bought 2 adapters, one I put on a laptop in usb 3.0, the second in a usb 2.0 computer . Naturally, in the process of settings I tried all the possible options that were generally voiced here . But I will describe what gave stable work . As already mentioned, the adapter works on channels up to 136, therefore, in the router settings for 5 GHz, channels above 136 had to be blacklisted, leaving auto selection . I have a speed of 600 Mbps on the wire. In a laptop via usb 2.0, the adapter gave out a maximum of 150, when connected at 5 GHz, and there were constant failures, the graph looked like a cardiogram . * By the way, the built-in wifi adapter gave out a stable 200 Mbps at 5 GHz . After switching to USB 3.0 wifi reaches 600, usually 500-540 Mbps . In a computer via usb 2.0 The same problems when connecting via 5 GHz, even worse, crashes and freezes were added . As a result, I switched to 2.4 GHz, the speed was maximum 90 -100 Mbps, but stable and smooth internet. In the adapter settings, uncheck "Allow the computer to turn off this device to save power" in the Power Management tab. In the Control Panel of the computer, in the settings of the power scheme used, in the advanced parameters - USB settings - the option to temporarily disable the USB port, set it to Disabled . By the way, the drivers had to be installed from a disk, in WIN10/64 on both devices. So if you don't have a DVD, etc., then take care of the firewood on the USB flash drive, you can download it from the off site. Hence the moral))) If your device does not have USB 3.0 and higher, your router does not have 5 GHz, then this adapter makes no sense . If there is, then you are very lucky)))
