Is it possible, though, to perform a self-installation of the Comcast internet using your own modem? Would you be able to set it up by yourself?

Can You Set Up Your Own Xfinity Internet?

As opposed to what many people believed, it is actually possible to set up your own Xfinity or Comcast internet if you have your own modem.

However, it is also worth noting that the modem/gateway needs to be eligible for the service for it to work.

Comcast offers a self-install procedure, which gives users the flexibility of activating or setting up their own internet services through the Xfinity app.

That being said, what’s the process of setting up Xfinity internet with own modem?

How to Self-Install Comcast Internet with Own Modem – Steps

Here’s the complete guide on self-installing Comcast or Xfinity internet using your own modem/gateway!

Step #1: Check the Eligibility of the Modem/Gateway

Before diving into the process, are you sure that you’re eligible for a self-install?

Comcast or Xfinity does not cover all devices and addresses. Therefore, it will be imperative to perform a check or a test to know what devices are compatible with the Xfinity or the Comcast network.

To check this, visit the Xfinity Supported Device list page and type in your address, as well as the download speed you’re looking for.

Then, click on Find Devices and the system will give you a list of the devices that’s capable of giving you the speed you’re looking for.

Step #2: Prepare All Needed Components

Once you’re done validating everything you need to check, the next thing you want to do is to prepare and gather all of the components for the process.

For self-installation like these, you can request an Xfinity self-installation kit.

This kit would contain the following:

• Wireless Gateway (modem or modem/router combo)
• Coaxial (Coax) Cable
• Power Cable
• Ethernet Cable
• Xfinity Documents
• Setup Instructions

Minus the Xfinity documents, the xFi gateway, and setup instructions, if you have all of those in-check, then you’re ready to rock!

Step #3: Install Xfinity Internet

Now that the easy part is done, let’s now head to the more complex and quite difficult part – the installation.

Unlike other guides, we’ll not give you a summary of the things you need to do.

Instead, we’ll be walking you through all these steps in complete detail!

1. Grab the coaxial cable and connect one end to the socket.
2. Then, take the other end and connect it to the gateway.
3. Ensure that the coax cable is plugged in tightly to both ports.
4. Plug the power cord of the gateway/modem into power through the outlet.
5. Wait for about 5 to 10 minutes for the system to reinitialize.

That’s it! That’s the hard part of the process. If you have even a bit of a technical background, you’ll be able to do this without a sweat!

It’s just a matter of assembling your hardware for it to work under Comcast or the Xfinity network.

Step #4: Activation Process

And last, but most definitely not least is the process of activation.

There are actually a few methods of how you can activate, and we’ll teach all of these to you, so you have all the options you need!

Activating Through Xfinity’s Customer Service

Probably the best and easiest way to activate it would be by calling Comcast’s customer service hotline. To do this, you just have to dial 1-855-955-2212.

From here, you’ll be greeted by Xfinity’s automated voice system, you just have to follow the prompts.

Once done, check the status of your modem and see if the internet light is flashing or if it is present. Alternatively, you can check the app and inspect if it’s there.

Activating Through the Xfinity App

Before, Xfinity users had the option to activate on the website. But now, they compressed it so that the online activation would go through the Xfinity app only.

To activate using the Xfinity app, follow these steps:

1. Download the Xfinity app on your device (iOS and Android compatible).
2. Once done, launch the app and sign in (Xfinity ID and password).
3. Click Start Activation on the app.
4. Since we’ve done all the steps here, just click Next.
5. Then, type in the CM MAC (12-digit) number of your modem.
6. Click Check Connection.

After this, your services should be activated! From here, you can test the speed, check the overview, and all other information about the service!

Once you’re done with this 4-step process, you should have your Comcast or your Xfinity internet services up!

Although in some cases, you must wait it out for 15 to 30 minutes, it wouldn’t actually take you an entire day!

My Comcast Internet is Not Active, What Should I Do?

Before contacting Comcast to ask for further help and assistance, you would want to do a self-check up of what you’ve done and accomplished.

• Check if all wires and cables are connected securely to their ports
• Make sure that the modem/gateway is receiving sufficient power
• Double-check the 12-digit number of your modem/gateway

Should you have carried out the inspection of these factors and you find that your modem/gateway is still not functional, contact Comcast’s customer service for help and assistance.

Inform them that you tried to perform a self-installation process, but it was unsuccessful.
