Nighthawk Ac1900 and Powerline 2000

I’ve had my AC1900 running for almost a year with no issues. So yesterday I purchased a Powerline 2000 to convert a couple of my devices to wired. When I attach the Powerline to my router it shuts down my WiFi. I even added a switch off of the Ac1900 and plugged the Powerline into it and within 30 seconds my WiFi is down. As soon as I remove the Powerlines my wireless comes back up. Any thoughts or recommendations. Thanks
