Most cable Internet providers allow you to use your own cable modem instead of renting one from them. Before purchasing your next SURFboard modem or upgrading your Internet speed, it is crucial to review your cable provider's modem compatibility list to ensure the modem aligns with your subscribed Internet speed plan.
A cable modem that is incompatible with your subscribed Internet speed can severely impact connectivity performance or may not connect to the Internet at all. Ensuring compatibility helps you maximize your Internet service and avoid unnecessary disruptions.
Why Compatibility Matters
SURFboard cable modems are designed to work with cable Internet service providers in the United States. However, the modem’s advertised Internet speed may exceed the speed plan your cable service provider allows the modem to handle. This discrepancy can lead to issues such as:
- Reduced connectivity performance.
- Intermittent Internet disconnections.
- Complete failure to connect to the Internet.
Therefore, verifying modem compatibility before making a purchase helps ensure a seamless and uninterrupted Internet experience.
Steps to Check Modem Compatibility
By following these steps, you can make an informed decision when purchasing or upgrading your SURFboard modem, ensuring it meets the requirements of your cable service provider and the speed plan you are subscribed to.
- Visit your cable Internet service provider's website.
- Locate the modem compatibility list or use the provider's compatibility tool.
- Find the SURFboard modem model you plan to purchase or are currently using.
- Ensure the modem is listed as compatible with your subscribed Internet speed plan.
NOTE: DOCSIS 3.1 cable modems with a 2.5 Gbps or 10 Gbps Ethernet port are compatible with Internet download speeds of 1 Gig and above.
