Why Use Your Own Modem?

Using your own modem with your Xfinity internet service offers many benefits. The most alluring is how much money you can save.

Cost Savings

Xfinity charges an additional $15/mo. to rent the xFi Gateway. That’s $180 per year, almost enough to cancel out the cost of buying your own modem. Since these devices typically last a few years, your cost savings really kick in during the second year, where you could be saving $150 or more per year.

Increased Flexibility

Not happy with your Xfinity internet service? Well, if you’re fortunate enough to live in an area with multiple cable internet providers, your modem will more than likely work with other internet providers. You can switch and not worry about buying a new modem.

Better Control

Using your own modem also gives you more custom control over your network and security. Third-party modems often come with advanced features, such as parental controls, network security, and quality of service (QoS) settings. These features allow you to prioritize bandwidth usage, which ensures that your devices receive the bandwidth they need for optimal performance.

Disadvantages of Using Your Own Equipment with Xfinity Internet

As great as the advantages are for running your own modem, there are potential drawbacks to keep in mind. 


The most significant is the lack of technical support. The nice thing about leasing the xFi Gateway is that when things go sideways, you’ll have support from Xfinity and a replacement if the device is malfunctioning. Most manufacturers include a warranty, but might be a good idea to purchase an extended warranty, just to have the peace of mind if your modem malfunctions.

Equipment Upgrades and Replacements

Additionally, you will get upgraded equipment from Xfinity as it becomes available, or if your current leased equipment can’t support updated standards. If you’re using your own equipment, you’ll have to buy a new one when yours becomes outdated.


When you lease equipment from Xfinity, you are guaranteed to receive the advertised internet speed that you are paying for as well as future speed upgrades. If you decide to use your own modem, you will be limited to the top speed the equipment is able to support, and that may not line up with your plan. In some cases, you may even experience slower speeds.


The xFi Gateway is designed to work with Xfinity internet. While the modems covered here are compatible, you will lose out on some features by using them. This includes a lack of access to millions of hotspots nationwide, device support from Xfinity, and access to advanced, integrated security.

Test Your Equipment

Whether you’re using your own equipment or leasing equipment from Xfinity, it is recommended that you run an internet speed test for your connection periodically. The speed test results will tell you how fast your connection is on the device from which you are running the test. It’s the easiest way to begin diagnosing issues with your Xfinity internet. 

The cost savings of using your own equipment are definitely attractive. As long as you know what the pitfalls are and either know how to troubleshoot hardware and networking issues on your own, or have purchased an extended warranty to protect yourself, using your own equipment is a great way to go.
