Please provide more details.

  1. How did you install the driver?
  2. What did you do while trying to get it to work?

Try this:

  boot.extraModulePackages = with config.boot.kernelPackages; [
    rtl8821au
  ];

If it doesn’t work, try this instead:

  boot.extraModulePackages = with config.boot.kernelPackages; [
    rtl88xxau-aircrack
  ];

In both cases you need to reboot after applying new configuration.
