how to install rtl8812au driver
Last Updated on May 24, 2021 by Walid Salame 3 Comments
In order for dual-band WiFi adapter with the rtl8812au driver to be used in the Kali Linux, you need to install rtl8812au driver.
Although there are few WiFi adapters that can be put into Monitor mode, those that use RealTek’s RTL88xxAU chipset are particularly well known as “capable”.
however the driver need to be installed in Kali Linux to work and to be able to start monitor mode,
to do so please follow this tutorial step by step..
install rtl8812au driver
The wireless network card is a USB interface, and the chip model is Realtek RTL8811AU. If the wireless network card is placed in the Windows environment, it can be plug and play without installing a driver. But if it is placed under Linux, it may involve reloading the driver. At least, it is so under Kali Linux.
The following methods are fully applicable to rtl8812AU, rtl8821AU and rtl8811AU installed in Linux, other USB wireless NIC drivers should be similar, the detailed process is as follows (please use root privileges for the following operations):
You can follow this tutorial video or check the details below
Install rtl8812au driver
Install linux headers in Kali linux
Because the kernel of the Kali Linux system itself is not very complete, some things are reduced. The kernel header file linux-headers is reflected here, which needs to be installed manually. Other operating systems are similar. This file should be used when installing the driver for a while. The following are the commands for the installation.
Before installation may need to update the software source
If the depot inside the child does not correspond to the first document, the next step may not be successful
which means you must to choose a suitable source software for their own
Through the above steps, we should already have the kernel header file installed.
Download rtl8812au driver
To download the source code, you first need to install the git tool on your own linux (kali comes with it), of course, we can also go directly to the online download, but the method is a bit too low, I do not recommend. We can go directly to the official website to download and install, but here is a lazy, use the command:
Next, what you need to do is clone the source code:
Install DKMS
DKMS (Dynamic Kernel Module Support) is a tool for automatically compiling and installing kernel modules and managing things such as drivers that directly access kernels
now to install the driver go to rtl8812au directory
Install the driver In the directory you moved earlier
Uninstall the driver ? In the same directory as before
When driver installation is completed, if you connect the WiFi adapter to the “Kali Linux” VM, the Wi-Fi item will appear in the network connection indicator in the upper right, and you can select the connection destination.
to check if the driver was installed type this command:
Now reboot the operating system and execute the following commands to get the driver to work:
Next, let’s put the WiFi adapter into monitor mode:
check for monitor mode
Let’s scan Wi-Fi networks:
now let’s capture handshake
with this command as i’m targeting Kali wifi network
As you can see, everything works.

Forest Laflamme says
For anyone who can’t make this work, I used this:
Once the git link is cloned and you have cd into the directory:
dkms status
If the module is marked as added, instead of install as in the walk-through, use:
dkms install -m “Name of module you just got with dkms status” -v “version number of dkms status”
it will take a while, then you can verify it’s installed with one last:
dkms status
Hi, I still cant get it to work, the cloned files does not contain any installation script and DKMS status returns nothing.

Warning: Beware of «multi-state» USB WiFi adapters. Some USB WiFi adapters have proprietary Windows drivers onboard. When plugged in, they act like a flash drive or CDROM and on Windows will attempt to start installing the Windows driver. That won’t work on Linux or MAC or any other non-Windows OS so the adapter sits there in flash drive or CDROM mode. The problem is that the state of the adapter has to be changed for the adapter to show up as the device that you expect, in this case, a WiFi adapter. Most modern Linux distributions ship with a utility called «usb-modeswitch» that will handle this issue for you if it has the correct information for your adapter. It is a good utility but if you buy adapters that are «multi-state,» that is one more potential headache you may have to deal with when something goes wrong. Often you can indentify adapters that are «multi-state» as they are advertised as «free driver» or «free installation driver.» If you are looking to buy a USB WiFi adapter for use on Linux, MAC OS, *NIX or anything besides Windows, it is a good idea to seek out single-state adapters.
Note: Some adapter makers change the chipsets in their products while keeping the same model number so please check to confirm that the product you plan to buy has the chipset you are expecting.
The installation instructions are for the novice user. Experienced users are welcome to alter the installation to meet their needs.
Temporary internet access is required for installation. There are numerous ways to enable temporary internet access depending on your hardware and situation. One method is to use tethering from a phone.. Another method to enable temporary internet access is to keep a wifi adapter that uses an in-kernel driver in your toolkit.
You will need to use the terminal interface. The quick way to open a terminal: Ctrl+Alt+T (hold down on the Ctrl and Alt keys then press the T key)
DKMS is used for the installation. DKMS is a system utility which will automatically recompile and install this driver when a new kernel is installed. DKMS is provided by and maintained by Dell.
It is recommended that you do not delete the driver directory after installation as the directory contains information and scripts that you may need in the future.
There is no need to disable Secure Mode to install this driver. If Secure Mode is properly setup on your system, this installation will support it.
Step 1: Open a terminal (Ctrl+Alt+T)
Step 2: Update the system (select the option for the OS you are using)
Step 3: Install the required packages (select the option for the OS you are using)
Step 4: Create a directory to hold the downloaded driver
Step 5: Move to the newly created directory
Step 6: Download the driver
Step 7: Move to the newly created driver directory
Step 8: Warning: this step only applies if you are installing to Raspberry Pi hardware.
Run a preparation script
Step 9: Run the installation script (For automated builds, use NoPrompt as an option)
A file called 8821au.conf will be installed in /etc/modeprobe.d by default.
This file will be read and applied to the driver on each system boot.
To edit the driver options file, run the edit-options.sh script.
Documentation for Driver Options is included in the file 8821au.conf .
Removal of the Driver
Note: This script should be used in the following situations:
- the driver is no longer needed
- a fresh start with default settings is needed
- a new version of the driver needs to be installed
- a major operating system upgrade is going to be applied
Note: This script removes everything that has been installed, with the exception of the packages installed in Step 3 and the driver directory. The driver directory can and probably should be deleted in most cases after running the script.
Step 1: Open a terminal (Ctrl+Alt+T)
Step 2: Move to the driver directory
Step 3: Run the removal script
Recommended WiFi Router/ Access Point Settings
Note: These are general recommendations, some of which may not apply to your specific situation.
Security: Set WPA2-AES. Do not set WPA2 mixed mode or WPA or TKIP.
Channel width for 2.4G: Set 20 MHz fixed width. Do not use 40 MHz or 20/40 automatic.
Channels for 2.4G: Set channel 1 or 6 or 11 depending on the congestion at your location. Do not set automatic channel selection.
Mode for 2.4G: For best performance, set «N only» if you no longer use B or G capable devices.
Network names: Do not set the 2.4G Network and the 5G Network to the same name. Note: Unfortunately many routers come with both networks set to the same name.
Channels for 5G: Not all devices are capable of using DFS channels. It may be necessary to set a fixed channel in the range of 36 to 48 or 149 to 161 in order for all of your devices to work on 5g. (for US, other countries may vary)
Best location for the wifi router/ access point: Near center of apartment or house, at least a couple of feet away from walls, in an elevated location.
Check congestion: There are apps available for smart phones that allow you to check the congestion levels on wifi channels. The apps generally go by the name of WiFi Analyzer or something similar.
After making and saving changes, reboot the router.
Set regulatory domain to correct setting in OS
Check the current setting
If you get 00, that is the default and may not provide optimal performance.
Set it temporarily
Note: Substitute your country code if you are not in the United States.
Set it permanently
Recommendations regarding USB
Moving your USB WiFi adapter to a different USB port has been known to fix a variety of problems. Problems include WiFi going on and off as well as connections coming and going.
If connecting your USB WiFi adapter to a desktop computer, use the USB ports on the rear of the computer. Why? The ports on the rear are directly connected to the motherboard which will reduce problems with interference and disconnection that can happen with front ports that use cables.
If your USB WiFi adapter is USB 3 capable then plug it into a USB 3 port.
Avoid USB 3.1 Gen 2 ports if possible as almost all currently available adapters have been tested with USB 3.1 Gen 1 (aka USB 3) and not with USB 3.1 Gen 2.
If you use an extension cable and your adapter is USB 3 capable, the cable needs to be USB 3 capable.
Some USB WiFi adapters require considerable electrical current and push the capabilities of the power available via USB port. One example is devices that use the Realtek 8814au chipset. Using a powered multiport USB extension can be a good idea in cases like this.

Realtek 8812au kali linux
2019-07-11: Updated to compile against kernel 5.2
Realtek 802.11ac (rtl8812au)
This is a fork of the Realtek 802.11ac (rtl8812au) v4.2.2 (7502.20130507) driver altered to build on Linux kernel version >= 3.10.
My D-Link DWA-171 wireless dual-band USB adapter needs the Realtek 8812au driver to work under Linux.
The current rtl8812au version (per nov. 20th 2013) doesn’t compile on Linux kernels >= 3.10 due to a change in the proc entry API, specifically the deprecation of the create_proc_entry() and create_proc_read_entry() functions in favor of the new proc_create() function.
The Makefile is preconfigured to handle most x86/PC versions. If you are compiling for something other than an intel x86 architecture, you need to first select the platform, e.g. for the Raspberry Pi, you need to set the I386 to n and the ARM_RPI to y:
There are many other platforms supported and some other advanced options, e.g. PCI instead of USB, but most won’t be needed.
The driver is built by running make , and can be tested by loading the built module using insmod :
After loading the module, a wireless network interface named Realtek 802.11n WLAN Adapter should be available.
Installing the driver is simply a matter of copying the built module into the correct location and updating module dependencies using depmod :
The driver module should now be loaded automatically.
Automatically rebuilds and installs on kernel updates. DKMS is in official sources of Ubuntu, for installation do:
