### DKMS
|
|
This driver can be installed using [DKMS]. This is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the `dkms` package, which on Debian (based) systems is done like this:
|
|
```
|
|
$ sudo apt-get install dkms
|
|
```
|
|
|
|
### Installation of Driver
|
|
In order to install the driver open a terminal in the directory with the source code and execute the following command:
|
|
```
|
|
$ sudo ./dkms-install.sh
|
|
```
|
|
|
|
### Removal of Driver
|
|
In order to remove the driver from your system open a terminal in the directory with the source code and execute the following command:
|
|
```
|
|
$ sudo ./dkms-remove.sh
|
|
```
|
|
|
|
### Build / Install with Make
|
|
For building & installing the driver with 'make' use
|
|
```
|
|
$ make
|
|
$ make install
|
|
```
|
|
|
|
### Using hostapd?
|
|
Check the documents folder for more information on how to setup wpa_cli and hostapd
|
|
support on these drivers. <br>For 802.11ac (high speed), the driver also needs to be loaded
|
|
with: <br>"modprobe -r 88XXau" && "modprobe 88XXau rtw_vht_enable=2"
|
|
```
|
|
# For a bit more info on AP/STA mode configuration, see following links:

```
|
|
|
|
### Download / Build / Install
|
|
Download
|
|
```
|
|
$ git clone -b v5.2.20 https://github.com/aircrack-ng/rtl8812au.git
|
|
$ cd rtl*
|
|
```
|
|
Package / Build dependencies (Kali)
|
|
```
|
|
$ apt-get install build-essential
|
|
$ apt-get install bc
|
|
$ apt-get install libelf-dev
|
|
$ apt-get install linux-headers-`uname -r`
|
|
```
|
|
For Raspberry (RPI 2/3) you will need kernel sources
|
|
```
|
|
$ wget "https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source" -O /usr/bin/rpi-source
|
|
$ chmod 755 /usr/bin/rpi-source
|
|
$ rpi-source
|
|
```
|
|
Then you need to download and compile the driver on the RPI
|
|
```
|
|
$ git clone https://github.com/aircrack-ng/rtl8812au -b v5.2.20
|
|
$ cd rtl*
|
|
$ make
|
|
$ cp 8812au.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
|
|
$ epmod -a
|
|
$ modprobe 88XXau
|
|
```
|
|
then run this step to change platform in Makefile, For RPI 2/3:
|
|
```
|
|
$ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
|
|
$ sed -i 's/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g' Makefile
|
|
```
|
|
But for RPI 3 B+ you will need to run those below
|
|
which builds the ARM64 arch driver:
|
|
```
|
|
$ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
|
|
$ sed -i 's/CONFIG_PLATFORM_ARM64_RPI = n/CONFIG_PLATFORM_ARM64_RPI = y/g' Makefile
|
|
```
|
|
|
|
### For setting monitor mode
|
|
1. Fix problematic interference in monitor mode.
|
|
```
|
|
$ airmon-ng check kill
|
|
```
|
|
You may also uncheck the box "Automatically connect to this network when it is avaiable" in nm-connection-editor. This only works if you have a saved wifi connection.
|
|
|
|
2. Set interface down
|
|
```
|
|
$ ip link set <wlan1> down
|
|
```
|
|
3. Set monitor mode
|
|
```
|
|
$ airmon-ng start <wlan1>
|
|
or
|
|
$ iw dev <wlan1> set type monitor
|
|
```
|
|
4. Set interface up
|
|
```
|
|
$ ip link set <wlan1> up
|
|
```
|
|
For setting TX power
|
|
```
|
|
$ iwconfig <wlan1> txpower 30
|
|
or
|
|
$ iw <wlan1> set txpower fixed 3000
|
|
```
|
|
### LED control
|
|
|
|
#### You can now control LED behaviour statically by Makefile, for example:
|
|
|
|
```sh
|
|
CONFIG_LED_ENABLE = n
|
|
```
|
|
value can be y or n
|
|
|
|
#### statically by module parameter in /etc/modprobe.d/8812au.conf or whatever, example:
|
|
|
|
```sh
|
|
options 88XXau rtw_led_enable=0
|
|
```
|
|
value can be 0 or 1
|
|
|
|
#### or dynamically by writing to /proc/net/rtl8812au/$(your interface name)/led_enable, for example:
|
|
|
|
```sh
|
|
$ echo "0" > /proc/net/rtl8812au/$(your interface name)/led_enable
|
|
```
|
|
value can be 0 or 1
|
|
|
|
#### check current value:
|
|
|
|
```sh
|
|
$ cat /proc/net/rtl8812au/$(your interface name)/led_enable
|
|
```
|
|
|
|
### Testing / Debug
|
|
```
|
|
Check "documents" and "tools" folders for information
|
|
We also got a Android APK tool for debugging several chipsets
|
|
```
|
|
|
|
|
|
### NetworkManager
|
|
|
|
Newer versions of NetworkManager got some options you might want to disable.
|
|
Simply add these lines into the NetworkManager.conf
|
|
```
|
|
[device]
|
|
wifi.scan-rand-mac-address=no
|
|
|
|
[ifupdown]
|
|
managed=false
|
|
|
|
[connection]
|
|
wifi.powersave=2
|
|
```
|
|
at the end of file /etc/NetworkManager/NetworkManager.conf and restart NetworkManager with the command:
|
|
```
|
|
$ sudo service NetworkManager restart
|
|
```
