If you’re considering new Xfinity internet service, you may have noticed an unexpected equipment rental charge added to the cost of service. At first glance, an extra $13/mo.* may not seem like much of an expense, but internet service fees can quickly add up if you’re not careful. One of the best ways to eliminate some of those fees and save on your monthly bill is to invest in your own modem, router or 2-in-1 gateway device.

What to look for in an Xfinity modem and router
If you’ve decided on purchasing your own equipment, there are a few features you’ll want to look out for to ensure that once you buy, you’re happy with your Xfinity internet performance.
- DOCSIS Technology – “Data Over Cable Service Interface Specification” or DOCSIS is used to transfer data quickly over the coaxial cable used for a cable TV and internet connection. This technology has evolved from the initial 1.0 version to today’s fastest DOCSIS 3.1 version.
- Maximum speed capability – If you purchase Xfinity’s Gigabit Pro plan, which comes with speeds up to 2,000 Mbps, you’re going to also want to purchase equipment that’s capable of handling speeds that fast. Your modem can hinder your internet speeds no matter what plan you’re paying for.
- Channel bonding – If you’re familiar with internet traffic, modem channels are like lanes on that highway. The more channels your modem has, the more internet traffic it can handle without issue. The NETGEAR C7000 – 1AZNAS, for example, has 32×8 channel bonding. That means it dedicates 32 channels to downloading data and 8 channels to uploading, which is perfect for Xfinity’s fastest speeds.
- Security – Make sure your router uses a password with nothing less than WPA2 or WPA3 encryption. Your home internet network can be the first virtual door to your entire home security system.
- App-based management – Many routers on today’s market come with apps that can simplify setup and network management. From these apps, you can monitor the users on your home Wi-Fi and be updated when your router needs software updates.
