Review on TP-Link Archer T3U USB WiFi Adapter - Dual Band Wireless Network Adapter with MU-MIMO Technology, USB 3.0, Supports Windows 10, 8, 7, XP/Mac OS X 10.9-10.14 by Seo Jun Seog ᠌

I needed to take it since the pre-installed network card in my laptop was so terrible that it was almost incompatible with Wi-Fi or only worked at very slow rates when it did operate. Now at 2Hz, it's consistently showing me 140 Mbps, which is four times as fast as it was before))) 5 Hz slips off, and may God bless him for it. You can turn it on for a little while and download a significant amount of data, and then you may set it at 2 Hz permanently. However until the problem with the 5 Hz Wi-Fi is fixed, I would not recommend making a purchase, since I am confident that the same quality can be found at a lower price in the 2 Hz market. But, in practice, only the 2 Hz Wi-Fi works reliably. It's a shame. I was hoping for more from TP-Link. I would be interested in hearing the opinions of their representatives, but I'm too lazy to write to the technical support team (since my speed has already increased by 4 times and is generally satisfactory). For the sake of 5 Hz, you should absolutely NOT TAKE IT!
