A wireless local area network (LAN) includes various devices, both hard-wired devices and wireless devices that allow communications between the devices and possibly to other devices in other networks, such as private computer networks and the Internet. The present invention allows wireless devices to sense and access various types of wireless networks, including IEEE 802.11a, 802.11b and 802.11g networks. Access to the wireless networks can be made with or without user intervention. The present invention provides an efficient and versatile means for wireless devices to communicate with other devices in a network.
