Internet

First. Check their site for official info on any possible local outages here;

https://www.xfinity.com/support/status 

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 

Hey there user_sf7kwh. We are happy to assist. I do have a couple questions in order for me to assist better. What is going on? Are you having trouble connecting all devices? Does your modem have a light on currently?

@user_sf7kwh 

Were you able to find any outage info on that site or in the app ?
