You'll need to upgrade your service/equipment.

Hopefully I can explain this.  I have two accounts, one at my house and one at another house.  One house has the XFi Gateway the other just has a cable modem.  Accounts are linked to one account.  When I try to access the XFi app, it say To access xFi, you'll need to upgrade your service/equipment.

Is that by design?  If not, how do I access the XFi app for the house that has the gateway?  Do I need to unlink accounts?

Thanks
