What do the XFINITY speed test results mean?
Download speeds: The XFINITY speed test will first measure your download speed in Mbps, which is how quickly your internet connection can download data. This number is most important for activities such as surfing the web, streaming and downloading files. Download speeds of 25 Mbps and higher are considered broadband.
Upload speeds: The test will next measure upload speed in Mbps, or how fast your connection will upload data. This number is most important for activities such as video conferencing, online gaming and uploading files. Upload speeds of 3 Mbps and higher are considered broadband.
Latency: Once the XFINITY speed test is complete, you will also see “Ping” with a measurement in milliseconds (ms). This number is most important for online tasks that require quick reaction times, such as online video games. The FCC does not identify a standard ping for broadband internet, but under 100 ms is usually sufficient for online gaming.
You’ve taken the XFINITY speed test, now what?
When testing your internet speeds over a LAN connection with no other devices connected, your speeds should be close to the advertised speeds from XFINITY. According to a recent FCC study, XFINITY average speeds were often higher than the advertised speeds for multiple speed tiers.
If you’re getting speeds less than 80% of the advertised speeds in your XFINITY internet plan with a wired connection, or significantly less than 50% over a Wi-Fi connection, there may be a few ways to try improving your speeds. When using a wired connection, upgrading your XFINITY modem may help boost speeds. For your Wi-Fi speeds, try these common ways to boost your Wi-Fi speeds.
Of course, a sure-fire way to boost internet speeds is to upgrade to a faster internet plan. XFINITY offers internet download speeds up to 2,000 Mbps in some areas. See what internet speeds are available from XFINITY and other providers in your area with Allconnect.
