D-Link Airpremier AG DWL-AG660

D-Link Airpremier AG DWL-AG660 ... expand or reconfigure their wireless networks as their organization grows. This tri-mode, dualband network card inserts into your notebook/laptop PC to provide you a versatile way to wirelessly connect to any one of three available wireless networks - 802.11b and the newer, faster 802.11g and 802.11a that operate in two discrete, non-interfering frequency bands, 2.4GHz and 5GHz.

If you're a network administrator, the versatile 802.11a/g compatible DWL-AG660 adapter gives you an immediate way to expand your existing 802.11b network and protect your overall wireless network investment. By installing DWL-AG660 network adapters in computers throughout your organization, your employees can access wireless Access Points and routers from their PCs. And as your company expands or reorganizes, you won't have to keep pulling and plugging Ethernet cables because no matter where the workstation is relocated, it’s still connected to the network.

When you add an 802.11a/g access point (D-Link DWL-7100AP, DWL-8200AP), you will have an end-to-end wireless solution capable of handling up to 15 times the user load of your current 802.11b network.

In addition to its compatibility with earlier 802.11b networks, the DWL-AG660 offers the robust speed, up to 108Mbps (Turbo mode), of the newer 802.11g standard, so everyone can work faster and more efficiently. In addition to the 2.4GHz frequency band operated by 802.11b and g, the 54Mbps 5GHz band used by 802.11a also offers a way to quickly transfer data in a frequency range that does not experience interference or interruptions from cordless phones, microwave ovens and other devices utilizing the 2.4GHz frequency.

Wi-Fi Protected Access in the DWL-AG660 provides the necessary security protocols and tools, so employees can communicate with colleagues confidentially, access sensitive company information or send data that is dynamically encrypted as it’s sent. Wi-Fi Protected Access lets you authorize and identify users based on a secret key that changes automatically at a regular interval. Used in conjunction with a RADIUS server, WPA uses TKIP (Temporal Key Integrity Protocol) to change the temporal key every 10,000 packets. This insures much greater security than the standard WEP security, which requires the keys to be changed manually.

The DWL-AG660 supports 802.1x authentication for protection against network intrusion. Used in conjunction with a RADIUS server, this function provides a means to verify the identity of the client before an access to the network is granted.

This function brings a lot of convenience (when used in conjunction with other 802.11g products) for users that do not incorporate a RADIUS server in their networks. Utilizing the Pre Shared Key mode of WPA, the DWLAG660 will obtain a new security key every time it connects to the 802.11g network. You only need to input your encryption information once in the configuration menu. With the DWL-AG660, you will automatically receive a new key every time you connect, doing away with the inconvenience of manual WEP key input.
