Speed problem with my new D-Link (DWA-130) USB Adapter

Question

I'm pretty new to Ubuntu, however I have taken some effort to follow some of the solutions from others on here with similar versions of my hardware, to no avail. Some of the solutions I've tried.

1. Install DWA-131 WiFi dongle driver under Ubuntu 14.04.4

2. D-Link DWA-130 rev E1 RTL8191SU Wont Connect to Network (14.04)

I'm getting desperate at this point. What am I missing? Please help!

I have a Windows 10 dual boot which runs the same USB adaptor at a much higher speed so I know the issue is not with the WiFi signal. (70+ Mbps vs 2-3 Mbps in Ubuntu)

My current Ubuntu version is 16.04 LTS and I get 4.13.0-32-generic. From uname -r

The result from lsusb is:
