Windows 10: Microsoft Display Adapter kills my Wifi Internet Speed

I have the Microsoft wireless adapter hooked up to my tv and I can connect to it fine via my surfacebook. But once I'm connected, ookla speed test goes from 300mbps to 1-5mbps, making my internet unusable. I've tried it multiple times and right when I disconnect the wireless adapter even mid-test my internet speed shoots up.

Microsoft Wireless Display Adapter kills my internet connection.

I just purchased the Microsoft Wireless Display Adapter. I've plugged it into my HDMI receiver and have tried to connect it with my home built Windows 10 PC. When I am able to connect to the wireless display adapter, my PC loses it's wifi internet access.
The system tray icon shows that my PC is connected to my wifi router but shows that there is no internet. Once I disconnect from the wireless display adapter and autofix my wireless internet connection, my internet comes back. This happens every time I try
to connect the wireless display adapter. What am I missing?

I'm connecting to my wifi router with a USB TP-Link Wireless N Adapter (TL-WN823N). My processor in an Intel i7-4790K. If I can't figure this thing out, it's going back to the store.
