networking – I can not get wifi to work (Ubuntu 18.04.1)

I am relatively new to Linux and have recently started online courses. After running Ubuntu via a virtual machine, I finally decided to move on to the ultimate switch to Ubuntu. There is only one problem, I can not run the wifi wifi. my wifi adapter = QCA6174 802.11ac wireless network adapter. I am on the Samsung Tab Pro S.
If someone can help, it would be greatly appreciated.
