Review on Enhance Internet Speed with TP-Link AC1200 Wireless Dual Band USB Adapter (Archer T4U V1) by Kiyoshi Nakazawa ᠌

If he works for you for a week, you rejoice early. All the fun will start later. One day your computer will go to sleep or reboot, and wake up left without a network. And when you try to connect to 5 GHz, your adapter will disappear from the system, then spontaneously install and cheat in all possible ways. Only 2 GHz will work. This is on a fresh system with licensed win10x64 with native drivers from the manufacturer's website. A request to 2022 support did not give exactly any result, the answer was in the style of "the fool himself", and our piece of iron with crooked drivers is not to blame. If your computer works 24*7 - this adapter is not for you. It accumulates errors and then you get a useless brick running at 2 GHz, and fixing this problem takes about an hour. Faced with this 2nd time, I just put in an older adapter with 5GHz support and did not even waste time. The Year 16 driver actually contains the Year 15 driver. The driver that selects win10 is newer and works, but does not save from this problem. My router is a fresh archer c7, also from tp-link. Changing ports usb3-usb2 does not help, the problem also occurs on usb2.
