This is a dual-band wifi USB adapter with a large antenna and activity indicator LED.
Please note the vendor id 10ec is inaccurate. The correct vendor id is 2357 but this is not yet in H-Node's database. There is an issue requesting to add it: https://h-node.org/issues/view/en/380
The status of Realtek's driver for this product is unclear, but it seems likely that it is not actively maintained.
The Aircrack-ng project has created a working driver based on Realtek's driver for this product. As of spring 2021 this project appears to be actively maintained. On Guix, the Aircrack-ng driver is available as the package rtl8812au-aircrack-ng-linux-module. The source code may be found here: https://github.com/aircrack-ng/rtl8812au
Some versions of this product may be using RTL8811AU rather than RTL8812AU. This article only refers to the RTL8812AU (feel free to update if you have tested the RTL8811AU version).
Using the Aircrack-ng driver, the device has worked on linux-libre kernel version 5.11 and several earlier 5.x kernels. Driver support tends to lag behind kernel upgrades by roughly a few weeks, so be aware that it won't always work with the very latest kernel.
Both 2.4 GHz and 5 GHz bands work well individually. They have not been tested simultaneously.
