WiFI using Realtek RTL8812AU not found (Ubuntu 16.04.3 LTS)

Currently I can't use Wifi on my Ubuntu 16.04.3 LTS. However same hardware works, when booting Win10, or using Ethernet on Ubuntu.

When setting up the machine (desktop and external wifi adapter) I did lsusb and recieved following information: Bus 001 Device 006: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter

So i used following tutorial to set it up using ethernet connection. It worked fine, with the same speed as on all other machines. I can't recall changing anything, what could have triggered this issue now. rfkill unblock all isn't helping.

Current information:
