Xfinity internet speeds

Comcast Xfinity is one of the fastest internet providers in the country, delivering reliable cable speeds from 75Mbps to 2,000Mbps. In some areas, Xfinity offers symmetrical speeds through its fiber-to-the-home network (up to a whopping 10,000Mbps) or its upgraded cable network.

According to Reviews.org’s Internet Speed Test, Xfinity customers averaged 243Mbps download speeds and 33Mbps upload speeds across 416,646 tests from September 2023 to September 2024. Customers experienced 19ms latency on average, making it ideal for gamers and live streamers. Xfinity’s speed test numbers are only barely behind Google Fiber, Verizon, and Cox, which get only about 1–24Mbps more download speed.

Data derived from results of the Reviews.org speed test, Dec. 1, 2023-Dec. 1, 2024.

Xfinity customers report the fastest internet speeds from 365 to 889Mbps in Illinois, Maryland, and California according to our speed test results. Three of the areas with the fastest average Xfinity speeds, Country Club Hills, Gurnee, and Glencoe, are in the Chicagoland area, which tracks because internet providers often get the best speeds in the suburbs of a major city.

Unfortunately, there are several reasons why some folks can’t get the fastest speeds. Firstly, Xfinity plans differ by the area. For example, Xfinity offers up to 1,200Mbps in Chattanooga but up to 2,000Mbps in Bothell.

Second, each plan outlines a typical download speed in the broadband facts label, which is the speed you are more likely to experience. Some labels indicate the typical speeds are even higher than the advertised speeds.

Even then, there are environmental and situational factors at play that affect all speed tiers. The age of the network infrastructure, congestion, weather, and your router location in your home can affect your speed.

This is Jacob's speed test in November 2024, in Ogden, Utah. The left shows the results of a test over a Wi-Fi connection in a room far from the router. The right shows the results of a test over a Wi-Fi connection in the same room as the router.

Above, I’ve included screenshots of the difference your router location can make on your speeds.

My friend Jacob Scholl and his fiancée live in Ogden, Utah, and have Xfinity’s 400Mbps plan at home. When Jacob ran a speed test on his work laptop, he only got around 43Mbps download speeds in his home office, which is located down a long hallway far away from the router. He ran the test again a few minutes later in the living room, where the router is located, and ended up getting 342Mbps—higher than the advertised download speed.

What’s the best internet speed to get from Xfinity?

My colleague Brianne Sandorf’s rule of thumb is to get about 100Mbps of download speed to cover your basic streaming, gaming, and browsing needs. A faster speed of 300Mbps and above can support greater usage needs, such as if you have three or more people in the home who are actively using the internet on their own devices.

To get an idea of what speeds you need, I recommend checking your internet speed to see what you’re currently working with. Next, take a look at the table below to see if you might benefit from a little more juice to fuel your household’s internet activities:

Speed
Recommended number of users
Activities
50Mbps1Web browsing, light social media use, streaming shows
100Mbps1–2Streaming 4K video, online multiplayer gaming, working from home
150Mbps1–3Streaming 4K video for up to 2 devices, online multiplayer gaming, making video calls on 1–2 devices
300Mbps3–5Streaming 4K video on 4–5 devices, playing online multiplayer games, having multiple people work from home, connecting 6–8 smart home devices

Are Xfinity speeds symmetrical?

Xfinity mostly offers asymmetrical speeds through its cable network—fast download speeds and slower upload speeds. However, in December 2023 Xfinity announced plans to upgrade its network to bring symmetrical speeds to some cable internet customers over the next few years.

The upgrade plan involves rolling out a new cable technology, ​​DOCSIS 4.0, or Full Duplex DOCSIS, capable of symmetrical speeds over a cable network.

DOCSIS stands for Data Over Cable Service Interface Specification, a telecommunication standard that describes networks capable of bringing internet access into your home using underground cable systems.

In some areas, Xfinity has built full fiber-to-the-home networks, which provide symmetrical speeds.

Which internet plan from Xfinity should I pick?

The best internet speed to get from Xfinity is the 400Mbps plan. It’s enough speed to support three to five people streaming 4K video on a few devices, playing multiplayer games, taking video calls, and connecting a Ring door camera.

If you have more people in your home, opt for Xfinity’s 600Mbps or 1,100Mbps plans. These plans amp up your speed so you can stream on more devices and sustain multiple power users who use the internet 24/7.

What can you do with 2,000Mbps speeds?

You can support just about any internet activity with a 2,000Mbps internet plan. That means you can download Microsoft Flight ​​Simulator (a 30GB file) in two minutes, stream Wicked in 4K, and connect 20 people to your Wi-Fi at the same time and without lag or buffering.

Most homes rarely need even gigabit internet speeds (1,000Mbps and above). With Xfinity, this is even more the case, since the majority of its network is built with cable, so you get fast download speeds but slower upload speeds. On the other hand, some 800,000 households can sign up for an Xfinity fiber plan, which offers fast upload speeds in addition to fast download speeds, so getting a gigabit plan could be worth it if you’re a content creator who wants the fastest speed possible to upload videos and photos.

Xfinity speed test FAQ

How fast is Xfinity Internet?

Xfinity offers plans ranging in speed from 75–2,000Mbps for its cable internet plans. You can also find Xfinity plans that deliver speeds up to 10,000Mbps over a fiber internet connection—but that is in limited areas.

Why is my Xfinity upload speed so slow?

Xfinity primarily offers cable internet services, so its upload speeds are much slower than its download speeds. Most of Xfinity’s cable internet plans deliver 10–35Mbps upload speed, which is plenty for most people since online activities primarily involve downloading data.

Some homes might experience interference with their connection, which can slow down both upload and download speeds. Your upload speeds can get faster if you try connecting your device to the router via an Ethernet cable, restarting the router, or making sure there are no thick walls between your device and the router.
