Alfa AWUS1900 wifi adaptor

[lash508]

Hi

I'm trying to install the Alfa Awus1900 wireless adapter on Ubuntu 24.04.1 LTS. I've downloaded the
Realtek rtl8814au driver from github. I've unziped the driver and followed these commands:


# build & install
```
$ git clone https://github.com/aircrack-ng/rtl8814au.git
$ cd rtl8814au
$ make
$ make install.

warning: the compiler differs from the one used to build the kernel
The kernel was built by: x86_64-linux-gnu-gcc-13 (Ubuntu 13.2.0-23ubuntu4) 13.2.0
You are using: gcc-13 (Ubuntu 13.2.0-23ubuntu4) 13.2.0


Does anyone know what the solution is?

Thank you

The warning can be ignored. You need to run make install with sudo:

sudo make install

You also need to make sure you sign the built module with mokutil (or disable SecureBoot in BIOS/EFI) so it loads.

Actually, you are better off using:

make 
sudo make dkms_install

.. or else you will have to build/install rtl8814au module every time you get a kernel update.

Hi

Thanks for your reply. I've disabled secure boot and it works now.

How do I sign the module?

With mokutil. Don't ask me for specifics. I personally think SecureBoot is more hassle than it's worth and don't use it.
