What is a good download speed?

According to the FCC, download speeds of at least 25 Mbps are considered good.

However, in reality, 25 Mbps seems to not be enough.

A good download speed should be at least 100 Mbps, and an upload speed should be at least 10 Mbps. 

With 100 Mbps, you can simultaneously watch Netflix or YouTube, attend Zoom meetings, and play most online games on multiple devices.

Despite that, some people can get by with fewer Mbps, while others require more.

How to determine if your Xfinity download speed is so slow?

The first step in determining your slow Xfinity download speed issue is to do a download speed test.

A speed test provides a reading of the speeds you're receiving through your Internet connection.

Before you start, keep in mind the following points:

  • Close any browser tabs or programs that are not related to the speed test and connect your computer to your network via Ethernet 

  • Take a test at various times of the day for a few days and keep note of your results

  • Avoid testing during peak hours

  • Use modern testing equipment because older devices may not be able to accurately gauge your Internet performance due to their hardware.

  • Choose a nearby testing server because the physical distance between your device and the testing server affects the test. 

  • Unplug any additional Internet-connected devices from your network while performing the test.

To be honest, testing your Internet performance on an online testing site is a piece of cake.

All you have to do is go to a speed test website, click the "GO" or "START" button, and wait a few seconds for the results to appear on the screen.

Consider the following example:

So, what kind of speeds do you get? 

If your speed score is high - between 100 and 200 Mbps - it means your poor download speed has nothing to do with the Internet. 

If your speed score is poor - less than 100 Mbps - this might indicate that the Internet is the issue. 

Keep in mind that your speeds will vary based on the number of users on your network at any one moment.

    Comcast upped my internet speed from 50 to 100 Mbps, so why don't I notice any difference?

      Hi, you don’t notice any difference because 50 Mbps is already more than enough for 99% of what a home Internet user does on a regular basis

    My internet speed with Comcast is advertised to be 600 Mpbs but I'm getting only 85 Mbps. I use ethernet connection. My modem can handle up to 600 Mbps. What's the issue?

      One possibility is that you are confusing Bits per second with BYTES per second. Usually your IPS (Comcast) advertises BITs/sec, but when you do a speed test, you may get the result as BYTES/sec. 600bps = 75 Bytes/sec
