Xfinity is one of the largest internet service providers in the U.S. with an impressive footprint spanning 36 states. Xfinity is known for its range of extremely fast internet speeds, generous data allowance, flexible term agreements, and a whole lot more. The recently launched Xfinity Fiber is a service that sets you up with multi-gig speeds powered by the latest Wi-Fi 6 system, known as the Gigabit X6.

In this article, we discuss some of the basics of the Gigabit X6 system and the requirements for Xfinity Internet. We hope this short guide will help you configure your system better to make the most of your Xfinity Internet speeds and network capacity. But before we move to that, let’s give you the good news―Xfinity Gigabit Pro now delivers faster speeds than before.

The Gigabit Pro Plan with Xfinity Internet Is Now Faster!

The Xfinity Gigabit Pro internet plan used to offer 6 Gbps of internet speeds―powered by pure Fiber―since the transition to Xfinity 10G network started, the speed it delivers has received a boost, and customers can now rely on equal upload and download speeds up to 10 Gbps. This, along with the unlimited data that comes with the plan, makes it an enticing offer for many, especially those who require extremely fast internet speeds to get work done. This mostly includes video editors, designers, small business owners, professional streamers, gamers, etc.

The Xfinity Gigabit Pro footprint is expected to increase, but at this time it is available only on demand in areas where the network capability supports such ultra-high symmetrical speeds. With a price tag of $299.95 per month, the plan does seem a little expensive but do remember that this speed tier is recommended for professionals who might need it. 

System Requirements for the X6 Gigabit Xfinity Internet

Once you have decided that you are going to get the Gigabit Pro plan for your home, there is a list of requirements and configurations you must do. This is because to be able to support the insanely high speeds of over 6 Gbps, your PC or laptop, system, processor, and memory should meet certain standards.

Let us take a look at what are the prerequisites to be able to use the X6 Gigabit Xfinity Internet.

Browser Requirements

To be able to access and fully utilize the multi-gig speeds up to 6 Gbps, you can use the following browsers and their respective versions.

  • Google Chrome: Ver 40.0.2403
  • Microsoft Edge (64-bit)
  • Mozilla Firefox (64-bit): Ver 40.0.3
  • Safari: Ver 6.2.8 or higher

Ethernet and Connectivity Requirements

To achieve a maximum speed of 1 Gbps on your desktop or laptop, you will most likely need a 1G copper Ethernet interface and an adapter. Pairing them up with a Cat5e or a newer Ethernet cable would work exactly how you want it to.

To get speeds up to 6 Gbps on a single computer attached to the wired connection, you'll need the following components:

  • A desktop PC or laptop with a PCIe expansion slot
  • A 10G PCIe network interface controller (NIC) adapter with a small form-factor pluggable (SFP) unit
  • A 10G enhanced multimode fiber (MMF) and a small form-factor pluggable (SFP) transceiver
  • A multimode fiber (MMF) LC patch cable

If you have multiple devices in your home and need the 6 Gbps Xfinity internet speed on more than one device you will need a compatible router to help with this. This router would connect at the Fiber handoff in your home and should support a throughput of 6 Gbps or higher. Plus, it should be in line with the following requirements:

  • A 10G router or firewall system
  • A 10G multimode fiber (MMF), with a small form-factor pluggable (SFP) transceiver
  • All additional equipment on the network should be able to reach 6 Gbps Xfinity Wi-Fi speed. The number of devices and configurations supported usually depends on the make and model of the router or firewall.

The Xfinity Wi-Fi 6E Advanced Gateway device that was recently launched by Comcast meets all the requirements of the network. It seamlessly allows you to connect all your favorite devices to 6 Gbps of Xfinity Wi-Fi internet speeds.

Memory, Operating System, and Processor

For this speed to work, your PC or laptop must be using Windows 10 (64-bit) or for MacBook users, Mac OS 10.8 Mountain Lion or a newer version.

Your laptop or PC should also have a processor equivalent to Quad-Core Intel Core i7 or higher. All of your systems should be on a solid-state drive (SSD).
