Frequently Asked Questions
Can I bring my own equipment to Comcast?
You can purchase your own retail modem for use with your XFINITY Internet and/or Voice service as long as the equipment is certified for our network. However, before making a purchase at the retailer of your choice, please visit mydeviceinfo.xfinity.com to find certified retail equipment that's compatible with your service.
What are my responsibilities when purchasing and using my own equipment with XFINITY service?
You are responsible for ensuring that your retail device is secure, certified and compatible by visiting mydeviceinfo.xfinity.com. We recommend that you remain aware of new developments in technology to better understand when replacing your retail device may be necessary.
You will be responsible for troubleshooting device-related issues using the manufacturer's user manual if we have confirmed that your XFINITY Internet or Voice service is functioning properly. You will also be responsible for configuring your wireless network's security settings, if applicable.

What does it mean if my equipment is "not supported" or "End of Life" (EOL)? And how do I determine that a piece of equipment is "not supported" or "EOL"?
If a device is "not supported" or "EOL", it's not certified for use on our network and will not be activated as new or replacement equipment. You can determine if a piece of equipment is "not supported" or "EOL" using mydeviceinfo.xfinity.com in a couple ways:
For existing XFINITY Internet or Voice customers, if you attempt to use a piece of equipment that's not supported or EOL, the equipment will automatically display with a yellow indicator and notification once you sign into mydeviceinfo.xfinity.com.
Using the search feature as described above, all My Device Info users can view equipment that's not certified for use on our network by clicking the Show Unsupported Devices filter.
What should I do if my older retail equipment is "not supported" or "EOL"?
To get the most out of your service, you should consider replacing your retail equipment if it has been identified as "not supported" or "EOL".
