      6Gbps is the maximum data transfer rate in the DOCSIS® 3.1 standard. In practice, your Internet speeds will be less, as the transfer rate through the CM1000 Gigabit Ethernet port is limited to 1Gbps. The transfer rate may also be reduced by the volume of network traffic or your service plan.

      †† Maximum rate is derived from DOCSIS® 3.1 specifications and actual throughput will vary depending on your Internet subscription with your provider.
