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 guaranteed, 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. The product may not be compatible with routers or gateways with firmware that has been altered, is based on open source programs, or is non-standard or outdated. Actual network speed may be limited by the rate of the product’s Ethernet WAN or LAN port, the rate supported by the network cable, Internet service provider factors and other environmental conditions.
