* 300 Mbps represents the maximum throughput you can achieve with the Internet plan provided by your cable service provider. Actual throughput will be lower than 300 Mbps, as this throughput is dependent on your contract with your cable service provider.

† 960 Mbps based on DOCSIS 3.0 throughput. Maximum speed varies depending on the service provided by the cable operator. IPv6 availability is dependent upon your ISP or service provider providing IPv6 capability

Speed references are provided, marketed, and sold by your broadband service provider and not Linksys. Actual performance may vary, including lower network speed and data throughput rate. Performance depends upon many factors, conditions and variables, including products used, number of users accessing the Internet, type of traffic generated by each user (interactive browsing versus video streaming), interference, and other adverse conditions. Actual data throughput will be lower than indicated and may depend on the mix of products used and external factors.© 2016 Belkin International, Inc. and/or its affiliates.
