The terms AV600 and 600Mbps are derived from applicable specifications and refer to the theoretical maximum physical-layer data transfer rate. Those terms are used on this product solely to indicate its compatibility with other AV600 or 600Mbps power line devices. Actual data speeds vary and may be limited by the products Ethernet port and other network conditions such as data traffic, electrical noise, and wiring issues. For better performance, power line devices should be deployed on the same electrical circuit and rated for the same Home Plug standard. A minimum of two power line devices are required to establish a power line connection.

If you are uncertain about your network conditions, you should consult an IT professional to assist in selecting a networking product. Maximum wireless transmission rates are the physical rates derived from IEEE Standard 802. 11 specifications. Range and coverage specifications along with the number of connected devices were defined according to test results under normal usage conditions. Actual wireless transmission rate, wireless coverage, and number of connected devices are not, and will vary as a result of 1) environmental factors, including building materials, physical objects and obstacles, 2) network conditions, including local interference, volume and density of traffic, product location, network complexity, and network overhead and 3) client limitations, including rated performance, location, connection quality, and client condition.

About power saving, actual power saved varies based on network conditions and environmental factors.
