The AyrMesh Hub2n is the "building block" for the second-generation AyrMesh network - DOES NOT MESH WITH THE ORIGINAL AYRMESH HUB (before Sept. 2013). The first AyrMesh Hub2n (called the "Gateway") is connected to your existing high-speed internet connection (router) and distributes it via Wi-Fi up to half a mile away. Additional AyrMesh Hubs (called "Remotes") can then be deployed as to extend your network even further. All AyrMesh Hub2n units are automatically self-configuring using information from the AyrMesh Portal. Makes sure to order an Ethernet cable long enough to reach from where it is mounted to the power supply. AVAILABLE IN THE U.S. AND CANADA ONLY - WE CANNOT SHIP TO P.O. BOXES - IF YOU HAVE AN ORIGINAL AYRMESH HUB NETWORK (purchased before Sept 2013) purchase original Hub in "Legacy" section to expand an original Hub network.
