I followed instruction on this post to install the driver. The wifi adapter seems to be working. However, it keeps dropping wifi connections and re-connecting every few minutes.
My machine has dual boots, Ubuntu 16.04 & Windows 10. And Windows 10 never drops the wifi. Doesn't seem to be the adapter or my home wifi issue.
