I purchased this wireless card off amazon The card

but for some reason even after going to Additional drivers and it finding the R8812au it worked once and then completely stopped working(it does not seem to start for some reason)

ive also used the pre-included disk but this is the error i get: 

 samuel@samuel-System-Product-Name:~$ sudo sh /media/samuel/REALTEK/linu
/install.sh

The correct driver - supposedly - is already in the repositories. No need to install that old script from Realtek (but it failed anyway so no harm done).

In Terminal, 

sudo apt update
sudo apt install rtl8812au-dkms

Reboot.

  • There's a bug in this driver that won't allow dkms to rebuild this on a kernel update. See my answer at https://askubuntu.com/questions/799108/2-dkms-drivers-wont-build-correctly-when-installing-new-kernel-after-software-u – heynnema May 24 '17 at 14:20
  • Fixed but @heynnema those 3 other files to edit appart from the first one where just completely empty – user153888 May 24 '17 at 22:31
  • @user153888 only the first two lines apply to the rtl8812au, and the version number for the first two lines might have changed, but you should have been able to find both locations. If the first edit went ok, then the second edit should have worked too. Open the paths in Nautilus file manager and see if there's just a small change to make those first two lines apply to your configuration. Please remember to vote for my answer if it was helpful. – heynnema May 24 '17 at 23:07
