Unable to access home network settings via Xfinity App

I am trying to access my home network settings via a computer (http://10.0.0.1/) and receive a message to use the Xfinity app. I then ensure my phone is connected to my home network and open the xfinity app, but there the "View Wifi Equipment" is not available.  I can only see my two devices (tv boxes).  I have uninstalled, redownloaded and reinstalled the app and still the same.  How can I restore access to the modem via my computer (http://10.0.0.1/) or access to "Allow admin tool access" in order for me to turn it on?
