Hello Sonnyjames87, thank you for creating a post regarding this concern. More times than not lagging is caused by a poor connection to the internet, if you have prepaid services I would suggest choosing a different hot spot for better results. You can down load the Xfinity Wi-Fi app to find the best hot spots in your area.
Hi Sonnyjames87, I don't see a private message or a reply back from you here so I will close this thread as completed. Feel free to create another post if you require further assistance, have a good day.
