Ubuntu 17.04 cannot detect Realtek RTL8812AE Wireless

Question

Currently struggle to get the wifi working on my new built. I have tried following the guide here Here is the result from lspci -knn | grep Net -A2:

24:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8812AE 802.11ac PCIe Wireless Network Adapter [10ec:8812] (rev 01)

Then with sudo lshw -C network:

I am currently using kernel 4.10.0-22-generic and, I have rtl8821ae in the modprode - result for lsmod | grep rtl:

Any other suggestions?
