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

(further I describe the procedure, only for those whose device does not work adequately out of the box (it turns off, there is not enough 5G, the speed is low, for some reason the drivers included and from the TP-Link website do not allow the device to work fully in the 5G range, with 2.4Gz no problems were noticed even from the box.)) In order to start using the device fully, you need to do the following: 1. Install Realtek USB WLAN Family Controller RTL8812BU drivers (because the device runs on Chip model: RTL8812BU) 2. Configure the router in the 5G settings through the admin panel (19220228.0.1) to channel 36, this allows you to increase the 5G speed. 3. Disable automatic driver ates in Windows. It was only thanks to these manipulations that I achieved such speed with 5G, I hope this will reduce nerves and time for setting up someone.
