Xfinity FAQs

A good internet speed for you can vary depending on what you use the internet for. For example, web browsing requires 1Mbps, video streaming requires 3-25Mbps, and video calling requires about 3-6Mbps. Multiple people sharing an internet connection and multiple devices using the internet simultaneously can also contribute to needing faster speeds. In general, a good download speed for the average household would be 15-20Mbps. 
Although many factors can affect your speed test results, in general, they are a great way to estimate your internet speed. In order to get a more accurate test reading be sure to restart your modem and router, pause all internet use, restart your computer, and clear your web browser’s cache before starting the test.
Speed tests are relatively quick, usually taking less than a minute to present your upload and download speed results.
If you’re not impressed with your current internet speeds, you can try moving your router to a more central location, adding a WiFi extender, and simply turning your modem off and on again. Still not impressed? Compare faster internet plan options using our search tool.
Download refers to the speed at which you are able to download anything from the internet (photos, videos, etc.) while upload involves uploading content to the internet (live streaming, video calling, etc.).
Your internet speeds could be reduced for several reasons. Do you have a greater number of devices connected? Are there more people online than usual? Has the amount of video content streaming increased? Any of these factors and more could be limiting your current speeds.
