I have been running a W7200 mesh network for a few months with Xfinity as my ISP.  It has been and is working just fine.

I am considering dropping Xfinity and using Fidium as my ISP. But before I can commit to Fidium, I need to be sure that my complete W7200 mesh network will function properly with Fidium.  Thus, I am currently in a testing pattern with the Fidium.

I have my Fidium ONT in bridge mode with a NEW W7200 unit (not attached to my Xfinity mesh) and it is responding to external pings.

I do not want to interrupt my current, functioning Xfinity (Access Point mode) Xfinity network with 40+ devices on it.

I want to setup a testing "Sandbox" with the new, Fidium ISP and my NEW W7200 in ROUTER MODE attached to it.  Then I will add one device at a time.

I would like to know how to do this in the app.  Sometimes the "new" W7200 on Fidium shows up as "can't be found" on my current Deco iphone app. Other times I can't see it in the app.

Thank you.
