Wifi starts fast and then drops


I have an MSI 17 in laptop that has worked fine until this week. All of a sudden my internet has dropped to become ridiculously slow. I know the internet connectivity is not my laptop as I have several other laptops on the network as well as phones, game consoles, etc, and they all work fine. I have an Intel Dual Band Wifi chip which I've tried updating the driver for and completely uninstalling and reinstalling. I've tried getting rid of my wifi profiles. I've resetting WinSock and different network services. Nothing seems to work whatsoever. Here are screen shots of the device dropping in speed:

My other computer (which is less powerful mind you) gets consistently under 20ms when pinging google.

Any help would be appreciated. This is my primary pc . I just felt like I've tried everything at this point.

The specific chip is the Intel Dial Band Wireless AC3165

Bear in mind that this using the methodology applied by other users is at your own risk.
