new modum issues

I took up the offer for the free new modum.  Got it.  No problem downloading the ap.  No problem installing the new modum.  No problem linking it to my computer.  Then, the app would now work to activate it.  After many tries, I had to return it to the Xfinity store.  I think the issue was that my phone could not get a strong enough connection without an active modum.  You may have created a loop.  I wish I could get the new modum without all the phone ap nonsense.
