Aprašymas

Easiest Way to Expand

If you're a network administrator, the versatile 802.11a/b/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.

End-to-End Wireless Solution

When you add an 802.11a/b/g access point (D-Link AirPremierAG DWL-7100AP) or router (D-Link AirPremierAG DI-784) to your wireless network, 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.

108Mbps Dualband High Speed

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 and 802.11a standards, so everyone can work faster and more efficiently. In addition to the 2.4GHz frequency band operated by 802.11b and g, the 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.

AES and 802.1x Support

The adapter supports AES enhanced security and 802.1x for user authentication, providing a formidable barrier to hackers and sniffers, allowing users to securely share data over the network.

WPA/WPA2 EAP Support

Enhanced security is provided with Wi-Fi Protected Access (WPA) to authorize and identify users based on a secret key that changes automatically at a regular interval. Used in conjunction with a RADIUS server, WPA/WPA2 employs 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 adapter supports WPA/WP A2-EAP (Extensible Authentication Protocol) for authentication of 802.11 clients using server-side digital certificates. EAP creates an SSL/TLS tunnel between each client and the authentication server, which protects subsequent user authentication exchange.

This function brings a lot of convenience for users who do not incorporate a RADIUS server in their networks. Utilizing the Pre Shared Key (PSK) mode of WPA/WPA2, the adapter gives each user a new security key every time he connects to the network. Users only need to input their encryption information once in the configuration menu. Each user will automatically receive a new key every time he connects, and the inconvenience of manual WEP key input is eliminated.
