Your Xfinity Internet service plan is "sized" to support all of your connected devices at the same time. It's often faster than a single device can handle, especially over a WiFi connection. While newer devices should be able to handle greater speeds over WiFi, older devices may not do as well — even under ideal conditions.
For faster speeds, try using an Ethernet connection instead. Speeds through a hardwired connection are naturally faster than speeds over WiFi because of potential wireless interference.
Speed details
To help you better understand what download speeds can be expected over WiFi with your service, we’ve calculated the expected WiFi throughput of some of today's leading devices using millions of speed test results.
You can look up the expected speed of your device and other popular devices using our Xfinity xFi Speed Test tool.
It's important to check your Xfinity Internet service plan from the Devices page on xfinity.com (scroll down to Data Usage Overview) My Account to confirm the maximum download speed regardless of device capabilities.
