Navigate to the support section of your ISP's official website. Search for keywords such as compatibility guide, approved equipment, or bring your own modem.
Note: Always use the official ISP domain to ensure the compatibility list is current and authorized.Input your hardware specifications
Enter your specific modem model number into the search field provided on the compatibility page. If the ISP provides a dropdown menu, select your exact tier of service to confirm that the modem supports your current internet speed plan.

Check the results for the required DOCSIS version, typically DOCSIS 3.0 or 3.1. Ensure your hardware matches or exceeds the ISP's minimum requirement for your region to prevent future service degradation.
Note: DOCSIS 3.1 is the current standard for most high-speed gigabit connections.Save the compatibility verification
Take a screenshot of the confirmation page or note the certification status provided by the ISP portal. This serves as proof of compliance should you encounter provisioning issues during the activation process.
