It's ridiculous to even try to communicate with Xfinity because I'm writing a message to a computer. It doesn't understand that I have a problem. I signed up for a new plan with faster internet speed and its no different. My husband is having heart issues and has been trying to use the EKG on his Kardia APP. The problem is the APP needs more of a signal than 26 - 47 mbps to run. I can be sitting under the modem and still get the same speed. This has been going before the upgrade and now.
