Guide to Xfinity Internet Setup Connection at Home

You have chosen Xfinity as your preferred internet provider, and you’re not alone. Xfinity has ranked among the top providers ever since Comcast introduced the brand in 2010. 

And this popularity doesn’t look like it’s going anywhere heading into 2023. USnews.com puts Xfinity at #3 for best internet service providers and #1 for the fastest high-speed internet providers of 2023. Needless to say, you’ve made a sound choice.

This doesn’t come as a shock considering that you can stream video, download files, use your favorite apps and work from home all with one network. And the price is the cherry on top (as low as $24.99 per month). 

Features of Xfinity internet

Enter the caveat: you don’t want to pay the installation fee, so you will install it yourself. This can be overwhelming for the seasoned, tech-savvy pro and paralyzing for the novice. 

But that’s why we’re here. This article will help alleviate your anxiety and make the installation process as easy as possible.


How is Xfinity Internet Installed

Installing your Xfinity internet is as easy as following a list of directions–provided that your residence is already connected to the Xfinity network. If it’s not, you’ll need a professional to come in and do it for you.

For all intents and purposes, however, let’s say your residence is. Below are the steps you need to follow to install your internet yourself. 

Steps to installing your Xfinity internet

Order Your Xfinity Self-Installation Kit

The first item on the list may be the most self-explanatory. You must order and possess an installation kit before you can install it. You can do this in one of two ways: have the kit shipped to your address when you order your service or contact Xfinity’s customer service.

Check if Your Kit is Complete

While Xfinity is known for world-class customer service, everyone makes mistakes. There is a chance–no matter how small–that your kit may come incomplete. So step two is to be sure yours contains the following:

What is included in Xfinity internet self-installation kit

  • xFi Wireless Gateway (modem/router combo)
  • Power cable
  • Coaxial cable
  • Ethernet cable
  • Getting started guide/setup instructions
  • Xfinity documentation (privacy policy, terms and conditions, etc.)
  • Instructions and prepaid labels in case you need to return stuff

Connect Your Modem

Connecting your modem is crucial, and the placement of it is equally essential. Generally, you want to place your modem in a central location (so it can reach all corners of your home) and away from obstructions that could weaken the signal strength. Then proceed to the following steps:

  • Step One: One end of the coaxial wire should be connected to the open coaxial outlet. Tighten it all the way by turning it to the right. The xFi Wireless Gateway should be connected to the opposite end of the cable.
  • Step Two: Connect the power cord to a wall socket before inserting it into the back of the gateway.
  • Step Three: Wait until the light for the online connection stops blinking and stays on for at least a minute.

Connect Your Devices

Connecting your devices is the next step. There are two ways to do this: connecting via Wi-fi or an Ethernet cable.

Via Wi-Fi

Go to the Wi-Fi setting on each device, select your network and enter the password. You can find your password on your gateway. 

Via Ethernet

To connect via an Ethernet, simply plug one cable into your computer or device and the other into the Ethernet port on your Xfinity gateway. 

Activate Your Xfinity Internet

Disclaimer: your Xfinity internet isn’t fully operational until you fully activate it. And there are a couple of ways to do this.

Via Web Browser

Xfinity provides an activation page that makes the process easy for you. All you have to do is go to the page and follow the prompts. 

Via Phone

Most people dread having to call a company on the phone but remember the world-class customer service? You have the option to call Xfinity’s activation number (1-855–652-3446) and follow the prompts there.

Via Mobile App

As the adage goes, “There’s an app for that.” Xfinity customers can download the mobile app, sign in to their Xfinity account, and follow the prompts. To do this, you may need the make and model of your Gateway. 


The Bottom Line

Deciding to install your Xfinity internet by yourself can seem daunting, but who wants to pay an installation fee? Fortunately, Xfinity has provided customers like you with a step-by-step guide to make the process effortless. 

Choosing Xfinity is a decision you likely won’t regret. You may never need to improve your connection, but–if you’re ever curious–you can visit this internet comparison tool.
