Comcast Xfinity offers internet service across the US, with speeds ranging from 50 Mbps all the way to a mind-boggling 2,000 Mbps. But you’ll most likely see a max download speed of 1,200 Mbps or slower in your area.

Speed test results show the average Xfinity download speed sits just above Mbps, and that could be partially attributed to a large number of customers subscribing to the 50 and 100 Mbps plans. It’s hard to tell since speed test results don’t report on which plan the test-taker is paying for.

One other thing to note about Xfinity internet speeds is that its average upload speed is about 15 Mbps. That’s a reasonable upload speed for your Zoom calls, but it may be a deal breaker for anyone running a Plex server or hosting livestreams. Xfinity’s faster plans are known to reach upload speeds around 30 Mbps, so if you find yourself in need of faster uploads, consider upgrading your plan.

These cities topped the charts for the fastest average Xfinity download speeds.

Xfinity speeds reach their pinnacle on the coasts, with cities in Massachusetts and Washington boasting the fastest average download speeds. (And props to Texas too.)

But that’s not to say you can’t get zippy Comcast speeds in other parts of the country. For example, in our home state of Utah, we regularly see download speeds that are right in line with the speed Xfinity advertises to us.

Xfinity’s minimum download speed of 50 Mbps is fairly decent for a single person or a couple who enjoy streaming Loki in HD or 4K and do a little bit of work at home.

But we recommend an Xfinity plan with 100 Mbps or more if you work from home on a regular basis, have a home security system, or do some online gaming in your downtime.

Xfinity’s max download speed of 1,000 Mbps isn’t really necessary unless you run a home business or are a creative professional. Or if you share your internet with three or more folks who also work from home, game, and stream—all at the same time.

• 50 Mbps: 1–2 people who stream video and do some work from home
• 100+ Mbps: 2+ people who work from home regularly, have a home security system, and game
• 1,000 Mbps: Home business owners and creative professionals, or those who share their internet with 3+ people who work from home

Still curious about Xfinity internet speeds? We’re here to help.

If you’re using Xfinity internet, you can visit any speed test site and analyze your internet speed right then and there. We might be biased, but we prefer using our own Reviews.org speed test, though there are plenty of other great speed test sites out there.

Xfinity also offers a speed test, but we recommend using a third-party site for the most accurate results.

Your Xfinity internet might be slow for a number of reasons, but some of the most common are:

• You’re sharing your internet with someone who’s downloading a game or other large files.
• Your modem and/or router are old and need an upgrade, software update, or reset.
• You’re using Wi-Fi instead of a wired connection (connecting to the internet with an Ethernet cable is always faster).
• Your computer has a virus or malware that’s hogging your internet connection.

The good news is that we’ve got tips for how to get around these common issues and speed up your internet.

Your Xfinity Wi-Fi might be slow for the usual reasons, like someone downloading a large file on your connection or your modem and router need an update. But Wi-Fi can also slow down if your router or Wi-Fi extender aren’t located in a central spot in your home.

That’s because obstructions like walls, furniture, and floors can slow down your Wi-Fi signal as it travels through these solid objects to reach your device.

If possible, make sure your wireless router or Wi-Fi extender is as close as possible to the connected devices you use the most—without moving it too far from other devices that need the internet too.

Your Xfinity internet should be as fast as the download speed advertised on your Xfinity internet plan.

Of course, normal, everyday issues like online traffic, your internet equipment, and the work you do online might slow down your Xfinity internet speeds. But they should still be as close to the advertised speed as possible.

Yes, Xfinity’s 100 Mbps internet plan is great for a small family (two to three people) who works online from time to time, likes to stream TV, and game online.

A good internet speed test result is one where your actual internet speed (the speed test result) matches or exceeds the speed that your internet provider advertises for the plan you’re paying for.

To check your Wi-Fi speed, make sure your device is using a wireless connection (and isn’t connected to the internet through an Ethernet cable).

Then, open up an internet speed test on your device and click the button to start your speed test. Wait a couple of minutes, and then your Wi-Fi speed results for your current download speed, upload speed, and latency (or ping) should appear.
