mr1100 incorrect wifi mobile router in netgear ios app

I get incorrect mobile router in the netgear ios mobile app.

If I factory reset the device it works fine but as soon as i change the ip address of the nighthawk to something other than 192.168.0.1, lets say 192.168.100.1, the app will no longer connect. I can access the device fine through a browser.

This appears to be an ongoing issue that only seems to be solved by resetting the mr1100 back to factory defaults and the factory ip address of 192.168.0.1.

Please Advise.

Thanks.
