How to Verify Your Modem Compatibility with Your ISP

Step by step

1. 1 min

   Locate the modem hardware identifiers

   Turn your modem over to find the manufacturer label. Note the manufacturer name, the exact model number, and the Hardware Revision (H/W Rev) version if listed.

   Note: Take a photo of this label to avoid typos during the search process.

   Access your ISP support portal

   Open your web browser and navigate directly to your ISP’s official equipment support page. Avoid third-party forums or reseller websites to ensure you are referencing the current, authorized device list.

   Note: Most major ISPs provide a direct 'Compatible Modems' URL accessible via their Help or Support site menu.

   Filter by your service speed tier

   Select your current internet service plan from the dropdown menus on the ISP compatibility page. Modems are often tiered; a device that supports 300 Mbps may not be certified for gigabit service even if it is produced by the same manufacturer.

   Note: Always choose the tier that matches your monthly billing statement.

   Match your model number against the list

   Cross-reference the model number found in Step 1 with the ISP’s generated list. Ensure the exact prefix and suffix of your model match the approved entry perfectly.

   Note: Partial matches or similar model numbers are often incompatible due to different internal chipsets.

   Validate the hardware revision

   If your ISP list includes a Hardware Revision column, ensure your unit’s H/W version is equal to or higher than the minimum requirement. Using an older revision of an approved model can lead to instability or failed activation.
