If you're accessing XFINITY Internet with an old modem, your equipment may not be capable of receiving the full range of your XFINITY Internet speed tier.
Upgrade Your Modem
If you want to enjoy our faster Internet speeds, such as Blast!, a DOCSIS 3.0 or above modem is required. You can rent our DOCSIS 3.0 or above Wireless Gateway, or you can buy an approved modem at a retail outlet near you. Please check mydeviceinfo.xfinity.com before purchasing to find a modem compatible with your chosen Internet speed tier. You can also check to see if your existing modem is approved at mydeviceinfo.xfinity.com.
