The following minimum system recommendations for your connected devices will ensure you’re getting the most out of your Xfinity Internet service.
If you meet the requirements but are not achieving the speed for your subscribed speed tier, please note:
- To achieve the upper range of your speed tier, you must be connected via a wired Ethernet connection.
- Speeds through a hardwired connection are inherently faster than speeds over WiFi due to potential wireless interference.
- There are a number of external factors that may limit your speed; as a result, actual speeds may vary.
- External factors that could impact speeds include:
- External interference
- Downloads/uploads in progress
- Open programs on your devices
- Number of devices connected to your home network
- External factors that could impact speeds include:
- Whenever possible, your Xfinity Gateway should be placed in a central, unobstructed location of your home, off the floor and away from other electronic devices.
- For better WiFi performance, see these tips.
- For better WiFi performance, see these tips.
Make sure that your internet equipment is up-to-date and able to support the speeds on your package. (For example, a DOCSIS 3.0 Internet device will not support Gigabit speeds from Xfinity.) You can check to see if you’re eligible for an equipment update at xfinity.com/equipmentupdate.

Speed tips
If you have hardware, software and related equipment configurations that can connect to the Internet but that are different from the above recommendations, they will still work with your Xfinity Internet service; however, our testing has shown that these recommendations will work best to achieve your provisioned broadband speed.
If you aren't experiencing the speeds you expect, remember to test using a hardwired connection to the internet. Also, make sure you are not in the process of downloading or uploading anything, close all programs using the Internet and power off any other devices that are sharing your home network.
Remember, there are a number of external factors that may limit your speed; as a result, actual speeds may vary. For the best performance, contact your device manufacturer or software provider to learn about required upgrades, configuration updates or to find troubleshooting guides.
For more information, check out the FAQs under My Results and Speed Factors on our Speed Test site.
WiFi speed tips
For wireless connections, you can improve your WiFi speed by positioning your Wireless Gateway centrally in order for it to broadcast its strongest signal. For better WiFi performance see these tips.
