I just purchased this item. 

1. I can't get the voice to work. The like flickers on the WiFi cable modem router, then goes off.  So, I don't the use of my phone.

2. I can no longer use my Xfinity streaming on my TVs. The WiFi connects to the TVs but won't stream any channels from Xfinity.

I uninstall the Xfinity Beta and reinstalled it, streaming services for Xfinity still does not work, but I can watch Netflix and Prime Videos. I can no longer watch local channels, either. I signed online to the Xfinity website and shows that it can not connect to my devices (TVs and phone).

Any suggestions

By the way I am not that computer literate.

Please post a copy and paste of the modems connection status page.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly. ISP will have to ensure the phone services and phone lines are working properly. 
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute then back ON.
