Approved Customer-Owned Modems

If cable modem service is available in your location, GCI will supply you a cable modem. We have thoroughly tested these devices for our network and supporting systems to ensure secure, reliable service at the highest possible data rates, and, if possible, to provide you with information about your usage. While GCI does not prohibit the use of any specific cable modems on its network, customer-provided cable modems may require GCI pre-certification. This process is necessary to ensure network security and to facilitate network management, service provisioning, and the availability of usage information. Any customer wishing to attach a non-GCI-certified modem to GCI’s network should send an inquiry to, and will be required to pay a fee for this certification process. Any Customer Equipment submitted for certification must, at a minimum, be DOCSIS 3.1, approved by the FCC and also be CableLabs DOCSIS certified.
