D-Link, the industry pioneer in wireless networking, introduces another breakthrough in wireless connectivity — the D-Link AirPremier AG DWL-AG660 Wireless Cardbus Adapter. This tri-mode, dualband adapter gives your laptop PC a versatile way to wirelessly connect to any one of three available wireless networks — 802.11b, 802.11g and 802.11a that operate in two discrete, non-interfering frequency bands: 2.4GHz and 5GHz. So, whether you’re at the office, school, at home or enjoying a cup of coffee at a public hotspot, you have the confidence in knowing whatever wireless network is active you can access.
