The AyrMesh Hub2T is the long-distance "building block" for the AyrMesh network. The first AyrMesh Hub (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 Hub 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. ONLY - WE CANNOT SHIP TO P.O. BOXES - IF YOU HAVE AN ORIGINAL AYRMESH HUB NETWORK (purchased before Sept 2013) contact us - the Hub2 series will NOT mesh with the original Hub.
