Use the My Device Info website to easily check if your device is approved for Xfinity Internet service. You can also use this site to ensure that your modem supports your selected Internet speed tier.
**Note**: If you don't know your level of service, learn by reading a full breakdown of your Xfinity services.
Before purchasing a retail device through a third-party retailer, visit the My Device Info page to better understand which devices are approved by Comcast. For more details, see the Frequently Asked Questions below.
Modem: This is the basic device you need to connect your home network to Comcast. A modem will provide a single ethernet connection. Most people connect the modem to a router in order to have more than one wired device and WiFi service. Some modems provide voice capabilities.
Gateway: Many people don't want to deal with a separate modem and router. A gateway device is a combination modem and router. They typically allow four wired connections and provide WiFi. Some gateway devices also provide voice capabilities.
Channels: These are communication paths. The more channels the better. This is expressed as downstream channels x upstream channels. So a device that is labeled "32x8" has 32 downstream channels and 8 upstream channels. Higher speed tiers require modems with more channels. Each channel can handle ~25Mbps, therefore an eight channel modem would be capable of ~200Mbps.
