    Please get a working internet connection by ethernet, tethering or whatever means possible. Open a terminal and do:

    Code:
    sudo apt update
    sudo apt install build-essential git dkms
    git clone https://github.com/whitebatman2/rtl8821CU.git
    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}
    Post back any errors, warnings, etc.
