I have been trying to resolve this problem but to no avail. I received xB7 modem/wifi router from Comcast and using that to connect to internet. The signal does not reach my basement and after a couple of weeks, at the end of 14 day evaluation period, they have sent me an Xfinity xfi Xpods. What I learned is that you can only activate xPods via your xFi App. When I aunch my xFi App, I do not see the option to activate xPods. Interestingly, my xFi app does not even recognize the fact that my xfi Gateway (Xb7 Model/Wireless Gateway) is already activated. When I go to Account -> Devices section, I only see the option to activate the xFi gateway.
When I click on the activate the xFi gateway, I get an error message.
Do you have more than one modem? I have a similar issue with the upgraded Xfi app whereby it only recognizes my voice modem and not the XFi modem. I also get stuck on the Initiate step and it never works.
