FastLane disconnects Extender in Nighthawk App

So I got this hooked up and everything seems fine, I can see the xtender in the Nighthawk app and interact with it jus tlike the router. However, if I got to the Extender through the web interface and turn on FastLane, immediately I lose the ability to connect with it through the Nighthawk app. If I look at the status of the Extender on the web page everything is working corectly, I can connect to it with devices, but the Nighthawk app just keeps saying issues connecting with "network_name". Go into the web page and turn off FastLane, it works fine but everything I have read it is prefered to use FastLane, so what am I doing wrong? Thanks in advance for your assistance. I am using the latest version of the iOS app and the latest firmware in the extender.
