    Is it a usb or pci device? – mikewhatever Oct 17 '16 at 4:14
  • It is a Realtek rtl8821a USB dongle. – Pilot6 Oct 17 '16 at 11:04
  • This is not a duplicate of generic questions. – Pilot6 Feb 20 '17 at 17:32

With a temporary working internet connection by ethernet, tethered or whatever means possible, please open a terminal and do:

sudo apt update
sudo apt install git
git clone https://github.com/diederikdehaas/rtl8812AU.git
cd rtl8812AU
make
sudo make install
sudo modprobe 8812au

You have compiled the driver for your current running kernel only. When Update Manager installs a later one, also known as linux-image, re-compile:

cd  rtl8812AU
make clean
make
sudo make install
sudo modprobe 8812au

    Are you sure it will work? The original Realtek source shows that it is 8821, not 8812. – Pilot6 Oct 17 '16 at 14:23
  • @Pilot6 Pretty sure. Please see post #53 here: ubuntuforums.org/showthread.php?t=2339960&page=6 It is the exact same 0bda:0811 device. – chili555 Oct 17 '16 at 14:54
  • @chili555 if it IS an 8812au, it's best to use rtl8812au-dkms from the repositories... however, I just grep'd my 8812au driver, and 0bda:0811 didn't show up, so maybe it is a 8821. Cheers, Al – heynnema Oct 17 '16 at 15:08
  • @heynnema The dkms won't build in most recent kernels. There is an AU post about the fix but I can't get it to work on my 4.8.0-xx kernel. I know the git version compiles (albeit with warnings) and covers the 0811 device. – chili555 Oct 17 '16 at 15:12
  • @chili555 I had sent you some info about how to fix the rtl8812au-dkms driver. It involves changing the MAKE command in dkms.conf. It's working for me with the latest in 16.04.1, but I can't speak to the 4.8.0 kernel. Cheers, Al – heynnema Oct 17 '16 at 15:17

I used synaptic and searched for rtl8812au-dkms . It worked perfectly once I unplugged and re-plugged the usb adapter. Hope this helps.
