Wireless drivers failing to build when make command is run

Question

I'll have to start by saying I'm new to ubuntu, and linux in general. I have set up a dual boot on my pc with windows and linux. Due to positioning in my house, I'm unable to get ethernet access, so I use an external wireless adapter that functions fine in windows. There ARE linux drivers, which I have downloaded on the system. So far, I've entered:

cd /usr/src/8812au-4.2.2
make

However, this fails to build. It returns with this:

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.2.0-27-generic/build M-/usr/src/8812au-4.2.2 modules
make[1]: Entering directory '/usr/src/linux-headers-4.2.0-27-generic'
  Building modules, stage 2.
  MODPOST 0 modules
make[1]: Leaving directory '/usr/src/linux-headers-4.2.0-27-generic'

From here, I'm not entirely sure where to go. If I try to continue, it finds that it doesn't build the 8812au.ko that I need.

Are there any ideas about what I could do from here?

EDIT: I downloaded the drivers from here: https://github.com/abperiasamy/rtl8812AU_8821AU_linux The drivers DO have instructions on using dkms, which also failed to work properly. Would you like to see what is returned when I try to install it through that?

Answer 1

This driver is included in Ubuntu repositories for Ubuntu 15.10 and 16.04. It can be also installed to Ubuntu 14.04.4 with 4.2 kernels (see the offline guide).

Most likely it will install on the previous kernels, but that is not guaranteed.

It can be installed for wily or xenial by

sudo apt-get install rtl8812au-dkms

You need to uninstall all other drivers for this adapter first.

You can install this driver offline this way:

1. Download these files to your Home directory

http://mirrors.kernel.org/ubuntu/pool/main/d/dkms/dkms_2.2.0.3-1.1ubuntu5.14.04.5_all.deb http://mirrors.kernel.org/ubuntu/pool/universe/r/rtl8812au/rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu1_all.deb

2. Run in terminal

   sudo dpkg -i dkms*.deb rtl8812au-dkms*.deb
