Solution 1:
Resolved.
I wiped the SSD and put the image on again.
Then straight away did
sudo apt purge rtl8812au-dkms
sudo apt install git
git clone https://github.com/gnab/rtl8812au.git
sudo cp -r rtl8812au /usr/src/rtl8812au-4.2.2
sudo dkms add -m rtl8812au -v 4.2.2
sudo dkms build -m rtl8812au -v 4.2.2
sudo dkms install -m rtl8812au -v 4.2.2
Rebooted and its working.
