Drivers for rtl8811CU and rtl8821CU Wi-Fi chipsets. This repository is based on soruce code found on a CD shipped with a rtl8811CU based card. It's updated to build on newer kernel versions.

DKMS 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:

apt-get install dkms

To make use of the DKMS feature with this project, do the following:

DRV_NAME=rtl8821CU
DRV_VERSION=5.2.5.3
sudo mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
git archive master | sudo tar -x -C /usr/src/${DRV_NAME}-${DRV_VERSION}
sudo dkms add -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms build -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms install -m ${DRV_NAME} -v ${DRV_VERSION}

If you later on want to remove it again, do the following:

DRV_NAME=rtl8821CU
DRV_VERSION=5.2.5.3
sudo dkms remove ${DRV_NAME}/${DRV_VERSION} --all

Use following commands in source directory:

make
sudo make install
sudo modprobe 8821cu

To build this driver on Raspberry Pi you need to set correct platform in Makefile. Change

CONFIG_PLATFORM_I386_PC = y
CONFIG_PLATFORM_ARM_RPI = n
CONFIG_PLATFORM_ARM_RPI3 = n

to

CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_ARM_RPI = y
CONFIG_PLATFORM_ARM_RPI3 = n

For the Raspberry Pi 3 you need to change it to

CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_ARM_RPI = n
CONFIG_PLATFORM_ARM_RPI3 = y
