    Abstract: A system and method for restricting access to a wireless network is disclosed herein. One or more access points are generally associated with the wireless network (e.g., an IEEE 802.11 wireless network), and a visitor gateway for automatically preventing visiting user from directly entering the wireless network. A command and control center communicates with the access points and the visitor gateway and controls data transfer and routing thereof. The visitor gateway can communicate with a remote computer network (e.g., the Internet) and restricts access to the wireless network by a visiting user through or from the remote computer network. The command and control center also can automatically route the visiting user to the visitor gateway when the visiting user attempts to access an access point associated with the wireless network.
