differences in the entry: Description
This is a dual-band wifi USB adapter with a large antenna and activity indicator LED.
Please note that the vendor id on this page [b]10ec[/b] is copied from another Realtek product on the wiki, as a temporary workaround since the actual vendor ID returned by `lsusb` is not yet in H-Node's database.
[h1]Driver[/h1]
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 [i]rtl8812au-aircrack-ng-linux-module[/i]. The source code may be found here:
[a]https://github.com/aircrack-ng/rtl8812au[/a]
[h1]Functionality[/h1]
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.
