Unimpeded Maximum. Currently, routers running the 802.11n standard have the longest range. The unimpeded range, at the same data rates, is roughly double that of the previous 802.11g standard.802.11g was widely regarded as having an effective range between 100 and 150 feet, meaning the 802.11n standard â the latest adopted standard available â covers roughly 200 to 300 feet.he unimpeded range, at the same data rates, is roughly double that of the previous 802.11g standard. 802.11g was widely regarded as having an effective range between 100 and 150 feet, meaning the 802.11n standard â the latest adopted standard available â covers roughly 200 to 300 feet.
Since a router typically has more Wi-Fi power than a client in a particular wireless connection, the router is hardly used at full capacity. For example, a three-stream 802.11ac router, such as the Linksys WRT1900AC, has a max Wi-Fi rate of 1,300 Mbps, but the iPhone 6s has a max Wi-Fi rate of just 833 Mbps (dual-stream).
