Cisco eliminates the worry over what type of network you have with their tri-mode adapter. It works in single mode for a, b, or g, dual mode a/g or tri-mode a/b/g for maximum connectivity.

Installation options are maximized with the included low-profile bracket for use in slimline and rack-mount systems. The PCI interface means compatibility with most systems. The remote antenna's 2 meter cable lets you place it for maximum signal strength and connectivity.

Since the need for security is at an all time high you have a choice between WEP, WPA and WPA2 protocols to protect your data and identity with no loss of transmission speed. In addition to data protection a secure network means that nobody is leeching bandwidth and slowing your network to a crawl.
