So I've been experimenting with Ubuntu on and off for a while, but I honestly have no idea what the hell I'm doing. So I have a realtek RTL8812bu WiFi dongle that I'm hoping to get working. I did some research, and came across this driver on GitHub that a couple people across two threads said worked for them:

At the bottom it said there is a new version here. So somewhere it said it was confirmed to work on kernels up to 4.16, so I checked and I'm on 4.15.0. But the problem I'm having, is what am I supposed to do? There is some installation guide at the bottom that is about as clear as mud to me since I don't know much.

  • Welcome to Ask Ubuntu! What version of Ubuntu are you using? – Kristopher Ives Sep 29 '18 at 1:12

Almost all of the instructions are in the README on the second site you linked. I’ll fill in a few blanks.

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

sudo apt-get update
sudo apt-get install build-essential dkms git
git clone https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.2.4.4_26334.20180126_COEX20171012-5044.git

Now, from the README:

cd rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044
VER=$(cat ./version)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

Please be aware that the ‘build’ process takes a few moments; please be patient.

Your wireless should now be working.

  • This one is for Kernel 5.3 but my installation either, thru dkms and sudo make install, both fails. github.com/cilynx/… – Infinite Loops Nov 27 '19 at 20:29
