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 

Good morning @user_ynrwaw, and thanks for posting your issue to the Xfinity forums, I hope this message finds you well.
