I recieved an email that said: Your Home WiFi Assessment is complete. Over the last 14 days, our advanced algorithm analyzed your use of WiFi in your home. Our results show that your coverage will benefit from a few xFi Pods. Three xFi Pods are available to you at no extra cost as part of your xFi Advantage service. But when I hit the "Get xfi Pods " tab i get an error message that says contact Comcast. When I call they don't know what I am talking about !!!
