User Manual for the NETGEAR 54 Mbps Wireless USB 2.0 Adapter WG121The NETGEAR 54 Mbps Wireless USB 2.0 Adapter WG121 has two interfaces: The USB 2.0 connector connects to any PC with an available USB port. The wireless antenna of the NETGEAR 54 Mbps Wireless USB 2.0 Adapter WG121 can beadjusted to optimize wireless communications. The LEDs indicate if the WG121 is connectedto a powered on PC, and the wireless link condition and signal quality of the NETGEAR 54Mbps Wireless USB 2.0 Adapter WG121 with another wireless node or the associated accesspoint.A Road Map for ‘How to Get There From Here’The introduction and adoption of any new technology can be a difficult process. Wirelesstechnology has removed one of the barriers to networking—running wires. It allows more peopleto try networking while at the same time exposes them to the inherent complexity of networking.General networking concepts, setup, and maintenance can be difficult to understand. In addition,wireless technology adds issues, such as range, interference, signal quality, and security to thepicture.To help overcome potential barriers to successfully using wireless networks, the table belowidentifies how to accomplish such things as connecting to a wireless network, assuring appropriatesecurity measures are taken, browsing the Internet through your wireless connection, exchangingfiles with other computers and using printers in the combined wireless and wired network.Introduction2-3
