ring doorbell live view

Hi

Recently my internet service was upgraded and I started using the latest highspeed modem from Xfinity. Everything works fine except that the ring door bell's live feature is not working. I spent 3 hours with Ring and around 30 mins with xfinity support. Ring team says its Xfinity is the issue as the live streaming is blocked and xfinity says they dont block anymore.

In an earlier thread here, they say that their problem was resolved once they changed the ring bell to use a static IP address. Unfortunately its not wokring for me.

Thanks

Manjunath.
