*Maximum performance derived from IEEE Standard 802.11ac draft specifications. Actual performance can vary, including lower wireless network capacity, data throughput rate, range, and coverage. Performance depends upon many factors, conditions and variables, including distance from the access point, volume of network traffic, building materials and construction, operating system used, mix of wireless products used, interference, and other adverse conditions. An 802.11ac router or access point will be needed to achieve 802.11ac performance.

†802.11ac 833 Mbps in the 5 GHz band is approximately 2.8X faster than 802.11n 300 Mbps in the 2.4 GHz band. The standard transmission rates—833 Mbps (for 5 GHz) and 300 Mbps (for 2.4 GHz)—are the physical data rates. Actual data throughput will be lower and may depend on the mix of wireless products used and external factors.
