## How to build a wireless driver?

Install and recreate kernel headers scripts (optional)

armbian-config -> install kernel headers
exit

cd /usr/src/linux-headers-$(uname -r)
make scripts

Go back to root directory and fetch sources (working example, use `ARCH=arm64` on 64bit system)

cd
export KSRC="/usr/src/linux-headers-$(uname -r)"
git clone https://github.com/pvaret/rtl8192cu-fixes.git
cd rtl8192cu-fixes
make -C "$KSRC" M="$PWD" ARCH=arm
Install kernel headers:

armbian-config --cmd SY004

Download driver sources:

git clone https://github.com/morrownr/8821au-20210708.git
cd 8821au-20210708
make
make install

Plug the USB wireless adaptor and issue a command:

iwconfig wlan0

You should see this:
