First. Check here for info about any possible local area outages;

Use a cell phone internet service, a public WiFi hotspot, or a neighbor's internet if you need to in order to check it.

Or you can use their Xfinity App: https://www.xfinity.com/apps  

Ensure the router is in a well-ventilated, central location away from
