## What it is
A Linux kernel driver for Realtek RTL8812AU/8821AU USB WiFi adapters supporting AC1200 (802.11ac) dual-band wireless. It is built from source with DKMS or make, with support for x86, Raspberry Pi, and NVIDIA Jetson Nano platforms.

## Use cases
- get a TP-Link Archer T4U USB WiFi adapter working on Linux
- install rtl8812au kernel driver on Ubuntu or Debian
- use an AC1200 802.11ac USB WiFi dongle on Raspberry Pi
- build a Realtek 8812AU driver for NVIDIA Jetson Nano
- cross-compile a WiFi driver for an ARM64 OpenWRT device
- enable dual-band 5GHz WiFi on a Linux machine via USB adapter

## When to choose
- you have a Realtek 8812AU/8821AU based USB WiFi adapter not supported out of the box by your Linux kernel
- you need 802.11ac dual-band WiFi on Raspberry Pi, Jetson Nano, or other ARM boards
- you want DKMS-managed automatic driver rebuilds across kernel updates

## When to avoid
- your WiFi chipset is already supported by the mainline Linux kernel
- you use a non-Linux operating system such as Windows or macOS
- you have a different Realtek chipset family (e.g., rtl8188, rtl8192)
