AWUS 1900 Build on PI4

[arkt0s-ctl]

Here is how i got ALFA AWUS1900 working on PI4 (PI OS!) 👍

sudo apt update
sudo apt upgrade
sudo apt install -y raspberrypi-kernel-headers build-essential dkms git
git clone https://github.com/aircrack-ng/rtl8814au.git
cd rtl8814au
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
export ARCH=arm
sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf
sudo make dkms_install
sudo reboot

Check driver existence

find /lib/modules/`uname -r`/ -name "8814au.ko"

Thank you!

Hi everyone,
I just tried to compile the drivers on a Raspi 4 with Lite OS (Bullseye) 64 bit, as per installation doc.

make dkms_install always results in an error. Anyone any idea how to get this solved?

Thanks in advance! 🙏

sudo make dkms_install
mkdir -p /usr/src/8814au-5.8.5.1
cp -r * /usr/src/8814au-5.8.5.1
dkms add -m 8814au -v 5.8.5.1

Creating symlink /var/lib/dkms/8814au/5.8.5.1/source ->
                 /usr/src/8814au-5.8.5.1

DKMS: add completed.
dkms build -m 8814au -v 5.8.5.1

I got it up and running using a different driver:

git clone https://github.com/aircrack-ng/rtl8812au
cd rtl8812au
make RTL8814=1 ARCH=arm64
sudo make install RTL8814=1 ARCH=arm64
sudo reboot

sorry for the late reply... medically induced downtime

it seem linux/ipx.h was removed in 5.15 ...

sadly iam not able to test any other driver , since i dont have the AWUS 1900 anymore ....

glad you found an alternative ....
