Xfinity Installation Guide
Installation Guide
Our Installation Guide
To get started, first check to see if the service is available in the area you are moving to. Once you've determined that service is available, you can either set up your equipment yourself or schedule installation with a technician.
Which Xfinity Setup Path Is Right for You?
Xfinity's setup process is flexible because not every customer is starting from the same situation. Here's a quick overview of the most common setup paths to help you figure out where to begin:
- New customer moving into a previously wired home: You'll likely be able to install it yourself using the Getting Started Kit. Xfinity will ship equipment to your new address, or you can pick it up at your nearest Xfinity Store.
- Customer moving from one Xfinity service area to another: You may be able to transfer your account and keep your existing equipment. Call Xfinity before your move to confirm that service is available at your new address and that your equipment will still work.
- Existing customer adding or upgrading service: Log into your account with your Xfinity ID to manage equipment upgrades. Depending on your plan, you may receive new equipment automatically or need to request it.
- Apartment resident or WiFi Ready building: Your setup process may be simplified or entirely different. See the "Xfinity Installation for Apartments and WiFi Ready Homes" section below for details.
- Customer who needs extra support: If you're not comfortable with self-installation or run into issues, professional installation is always available. See "When Professional Installation Is the Better Option" below.
Professional Installation vs. Self-Installation
Even if you're not a tech-savvy person, the self-installation process through Xfinity is simple and straightforward. Self-installation lets you install Xfinity anytime, day or night, without scheduling an appointment. Meanwhile, technicians will usually set installation appointments within a two to four-hour window.
Your Self-Installation Kit
If you're self-installing, you will need to place an order with Xfinity to have the Getting Started Kit shipped to your address or the nearest Xfinity Store. This can be done when you order your service, or you can contact customer service to place your order.
Your Xfinity Internet Getting Started Kit Will Include:
The kit comes complete with:
- An Xfinity envelope containing the Comcast Customer Privacy Notice and Agreement for Residential Services
- A Getting Started Guide
- A coax cable
- A power cord
Depending on your plan and equipment tier, your kit may also include:
- An Xfinity Gateway (modem/router combo) or a standalone modem
- WiFi Boost Pods, if included with your plan or ordered separately
- A printed Quick Start card with step-by-step setup instructions
- App activation guidance directing you to download the Xfinity Home app to complete setup from your phone
Note: Kit contents may vary depending on your service plan, the equipment assigned to your account, and whether you're a new customer or upgrading your existing service. If anything appears to be missing from your kit, contact Xfinity customer service before proceeding.
How To Self-Install Xfinity Internet
Xfinity Internet offers easy-to-follow videos for new users. After you have verified that your Getting Started Kit contains all the items listed above, you can proceed with the installation using the video guides below to set up, connect, and activate your service.

How To Activate Xfinity Internet with the Xfinity App
Once your equipment is physically connected, activating your service through the Xfinity app is the fastest and most straightforward method. Here's how it works:
1. Download the Xfinity app on your smartphone (available for iOS and Android) before beginning setup, or use mobile data to download it once your Gateway is connected but not yet activated.
2. Sign in to your Xfinity account. If you're a new customer, you'll create your account credentials during this step.
3. Follow the in-app prompts. The app will walk you through connecting your Gateway, scanning a QR code on your device if prompted, and confirming your address.
4. Wait for activation. The activation process typically takes 5–15 minutes. Your Gateway lights will change colors while it activates, which is completely normal.
5. Test your connection. Once activation is complete, the app will confirm you're online. Connect a device to your new WiFi network to verify everything is working.
Common activation issues to watch for:
- App not recognizing your equipment: Make sure your coax cable is snug at both ends and that the wall outlet is working. Try restarting the Gateway and refreshing the app.
- Activation taking longer than 15–20 minutes: Restart the Gateway by unplugging it for 30 seconds. If the issue persists, contact Xfinity support via the app's chat feature.
- "Account not found" error: Make sure you're signing in with the same email you used to create your Xfinity account.
- No Internet after activation confirms: Try forgetting the WiFi network on your device and reconnecting. If that doesn't work, a factory reset of the Gateway may be needed — the app can walk you through this.
Device-Specific Setup Guides
Xfinity offers several types of equipment depending on your plan. Here's what you need to know about setting up each one:
Xfinity Gateway
The Xfinity Gateway is an all-in-one modem and router. It manages your Internet connection and broadcasts your home WiFi network. To set it up:
- Connect the coax cable from your wall outlet to the "Cable" port on the back of the Gateway.
- Plug in the power cord and wait for the Gateway to boot up (allow up to 10 minutes).
- Open the Xfinity app to complete activation as described above.
- Once active, your default WiFi network name and password are printed on a label on the Gateway itself.
For the best coverage, place your WiFi equipment in a central spot in your home, off the floor.
WiFi Boost Pods
WiFi Boost Pods extend your Xfinity xFi network to eliminate dead zones in larger homes. To set them up:
- Your Gateway must be fully activated before adding Boost Pods.
- Plug a Boost Pod into any standard electrical outlet in an area with a weak signal.
- Open the Xfinity app, go to "Connect," and select "Add a Device."
- Follow the prompts to pair the Pod to your network. This typically takes 3–5 minutes per Pod.
Remember: WiFi Boost Pods are only compatible with the Xfinity xFi Gateway. They will not work with third-party modems or routers.
X1 TV Equipment
If your plan includes Xfinity X1, you'll set up your TV Box separately from your Internet equipment. Here's how:
- Connect the HDMI cable from your X1 Box to your TV.
- Connect the coax cable from your wall outlet to the X1 Box.
- Plug in the power cord — the box will power on automatically.
- Follow the on-screen setup prompts using your X1 voice remote.
- If prompted, sign in with your Xfinity credentials to access your full channel lineup and on-demand library.
Setup typically takes 10–20 minutes as the box downloads the latest software update. Simple Getting Started Guides for our TV offerings are available here.
Xumo Stream Box
The Xumo Stream Box is Xfinity's streaming device for customers who want a simplified TV experience without a full X1 subscription. To set it up:
- Plug the Xumo Stream Box into an HDMI port on your TV.
- Connect the power cable.
- Select the correct HDMI input on your TV.
- Follow the on-screen instructions to connect to your Xfinity WiFi network and sign in to your account.
- Once signed in, you'll have access to live TV, on-demand content, and popular streaming apps.
Note: The Xumo Stream Box requires an active Xfinity Internet connection and a compatible Xfinity TV plan.
Troubleshooting During Self-Install
Running into a snag? These are the most common issues customers encounter during self-installation and how to resolve them:
- No Internet connection after activation: Check that the coax cable is securely connected at both the wall outlet and the Gateway. Verify the outlet is active by testing with another device if possible. Restart the Gateway by unplugging it for 30 seconds, then try activating again through the Xfinity app.
- Weak WiFi signal in parts of your home: Reposition your Gateway to a more central location. If the problem persists across a larger area, WiFi Boost Pods can extend coverage. You can order them through the Xfinity app or at an Xfinity Store.
- Xfinity app not working or freezing during setup: Force-close the app and reopen it. Also, be sure to check that your phone's software is up to date. Older versions can cause the app to freeze or behave unexpectedly. If you're on iOS, check that the app has permission to use your local network (Settings > Xfinity > Local Network).
- Gateway lights blinking or showing unexpected colors: A blinking white light means the Gateway is connecting — this is normal during setup. A blinking orange light usually means there's a signal problem. Check all cable connections, then restart the Gateway. If it stays orange for more than 15 minutes, the coax outlet you're using may not be active.
- Coax outlet doesn't appear to be active: Not all coax outlets in a home are wired and active. Try a different outlet if one is available. If no outlets work, a technician will need to activate or add a line — in this case, schedule professional installation.
- When to call Xfinity support: If you've worked through the steps above and still can't get online, contact Xfinity at 1-800-XFINITY (1-800-934-6489) or open a chat at xfinity.com/support/contact-us. Have your account number and equipment serial number ready to speed up the process.
Xfinity Installation for Apartments and WiFi Ready Homes
The installation process can look quite different depending on your living situation. Here's what apartment residents and those moving into WiFi Ready buildings need to know:
Apartments and Multi-Unit Buildings
Many apartment buildings already have Xfinity coax lines installed. If your unit has an active coax outlet, self-installation should be simple and quick.
However, if your unit has never had Xfinity service or the outlet isn't active, the building's property manager will need to coordinate with Xfinity to activate the line. Contact Xfinity before scheduling self-installation to confirm your outlet status.
WiFi Ready Buildings
Some apartment communities have partnered with Xfinity to offer "WiFi Ready" units, meaning the building's Internet infrastructure is already set up and active. In these homes:
- No modem or Gateway installation is required. The building provides the network infrastructure.
- You simply connect your devices to the building's Xfinity WiFi network using the credentials provided by your property manager.
- Instead of activating hardware, you'll activate your account either through the Xfinity app or by calling customer service with your unit details.
If you're not sure if your building is WiFi Ready, ask your property manager or check with Xfinity when signing up for service.
What If I Can’t Install Xfinity WiFi Myself?
Sometimes, you cannot complete the installation yourself. Regardless of the reason, there are a few options available to you.
Set An Appointment
Technician Support
Your technician will schedule your appointment within a two- to four-hour window. Though the customer service representative will try to schedule the best they can, they cannot foresee unexpected circumstances that may delay the technician.
If your house has not been wired before, the installation process can take up to four hours.
Be Prepared
To expedite installation, it is best to prepare:
- Have computers, TVs, etc, available at the time of installation.
- Have access to existing cable outlets or know where you want them installed.
- Make sure all pets are secured.
When Professional Installation Is the Better Option
Self-installation works well for most customers, but there are definitely situations where scheduling a professional technician is the smarter call:
- Your home has never been wired for cable: If there are no active coax outlets in your home, a technician will need to run new lines. This isn’t something that you should do yourself.
- No active coax outlet is available: Even if your home has coax outlets, they may not all be active. A technician can test and activate outlets or install new ones if needed.
- Complex home layouts: Large homes, multi-story houses, or homes with unusual layouts may need a technician to position equipment and ensure full coverage properly.
- You're bundling Internet, TV, and Voice services: When you're adding phone service that uses physical jacks, the setup is more involved. A technician can make sure everything is connected and working correctly from the start.
- You've tried self-installation and can't get online: If you've followed all the troubleshooting steps and still can't get your service to work, it's time to bring in a professional. The problem may be a line or signal issue that only a technician can fix in person.
To schedule professional installation, contact Xfinity at 1-800-XFINITY or visit xfinity.com.
The bottom line:
Xfinity has optimized self-installation with an all-encompassing kit, easy-to-follow instructions, and technical help when needed. Though professional technicians are available for installation, self-installation is easy and can be done on your own time.
Xfinity Installation Guide FAQs
Yes, Xfinity allows customers to use their own DOCSIS 3.0 or 3.1 compatible modems, which can save you the monthly equipment rental fee. If you use your own modem, you won't have access to xFi features like parental controls and device management through the Xfinity app, and you won't be able to use WiFi Boost Pods. Check Xfinity's approved device list before purchasing.
