Is it hard to install Xfinity Internet yourself?
It is not hard to activate your Xfinity internet. However, the process takes up to 30 minutes. To activate your Xfinity Gateway or modem, you can go to xfinity.com/activate and follow the on-screen prompts. This will allow you to verify your account and complete the process of activation Once a temporary Internet connection is established via Comcast's modem, open any browser such as Chrome or Firefox and log in at www.xfinity.com/activate. You'll be prompted with what appears like an email verification page; this isn't spam but it does require confirmation for security purposes before proceeding further into setup. All that's left after this step is entering billing information (if not part of the already existing package) followed by finalizing the setup.
