Connecting my new internet service

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

First, I want to say I'm sorry for your loss. I've been in your shoes and know how it feels. I hope you and everyone in your family are doing well. I understand you recently signed up for your service, but you need some help getting online. We got your back. We are a full service team, so you've come to the right place. 

The Xfinity App is also full of resources that allow you to complete activation online. Here https://www.xfinity.com/support/articles/how-to-activate-your-self-install-devices?view=app, you can find a step-by-step guide depending on what service you have. Can you let me know what steps you've taken so far, and the troubles your currently running into?
