    Hello there,

    just installed today max2play on my Raspberry Pi 3 with the Wifi adapter D-Link DWA-182 (Version C) which includes the rt8812au chipset. The module itself is not included in the default max2play images, but after a few steps its ready:

    Note: Make sure you have extended the space on your sd card because we need some extra space.

    1. Login via ssh onto your max2play device and execute the following steps

    2. Download rpi-source [1]
    sudo wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/bin/rpi-source && sudo chmod +x /usr/bin/rpi-source && /usr/bin/rpi-source -q --tag-update

    3. Install bc (required by rpi-source)
    sudo apt-get install bc

    4. Run rpi-source to get the required kernel headers
    rpi-source

    5. Get the rtl8812au module sources from github [2]
    git clone https://github.com/gnab/rtl8812au.git

    6. Change into the rtl8812au directory and edit the Makefile with vi to match following snippet

    …
    CONFIG_PLATFORM_I386_PC = n
    …
    CONFIG_PLATFORM_ARM_RPI = y

    7. Run make and install the module
    make
    sudo insmod 8812au.ko
    sudo cp 8812au.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless
    sudo depmod

    8. Disable the integrated wifi chip [3]
    Add the following lines to the file /etc/modprobe.d/raspi-blacklist.conf (if it not exists, then create it)

    blacklist brcmfmac
    blacklist brcmutil

    9. Reboote
    Now the wifi settings can be setup in the wifi tab in the max2play ui.

    Maybe the module could be included in the next versions of max2play (and also the ability to deactive the integrated wifi chip)? 🙂

    Great Howto, Adam!
    Thanks for contributing this instruction to our community, I’m sure it will help others using this WiFi dongle. We will consider including it in a future release of Max2Play.

    Hi Adam,
    We are manufacturer of usb wifi adapter, one of our long range usb wifi adapter is integrated with the same Realtek RTL8812AU wifi chip.
    We are looking for someone to write an installation manual for installing it on Raspberry PI. And we are willing to pay for this.
    Are you interested in this? if yes, please kindly contact us by sending email at [email protected]
    Your response is awaited.
    Thanks!
    Allen

    Hallo
    Irgendwie funktioniert die Installation auf meinen Raspberry Pi 3B+ nicht.
    Auch Install funktioniert nicht.
    WLAN0 wird nicht gestartet 🙁
    Successfully initialized wpa_supplicant
    Could not read interface wlan0 flags: No such device
    WEXT: Could not set interface ‚wlan0‘ UP
    wlan0: Failed to initialize driver interface
    ifup: failed to bring up wlan0

    Kann mir jemand helfen?

    Gruß
    Alex
