D-Link DWL-G520 108Mbit/s networking card

DWL-G520 - 108 Mbit/s The D-Link AirPlus XtremeG DWL-G520 Wireless PCI card is an enhanced 802.11g high-performance, wireless card for desktop computers. This card supports high-speed wireless networking of up to 108Mbps, while providing seamless interoperability with all existing 802.11b and 802.11b+ wireless equipment. Together with better security, this card is the ideal wireless solution that offers an upgrade to a fast, new technology while protecting your past investments through interoperability with your current network equipment.

Up to 108Mbps Transmission Speed
Unlike most wireless cards, the DWL-G520 provides speeds of up to 108Mbps when used with other D-Link AirPlus XtremeG and other 802.11g products. This compares favorably with 802.11b adapters that offer 11Mbps speed, and with 802.11b+ adapters that give 22Mbps transmission.
This enhanced speed and adoption of 2.4GHz frequency, now available for public use in most countries, plus the mobility and convenience inherent in a wireless LAN, make this card an ideal solution for bandwidth intensive WLAN applications.

Compatible With 802.11b and 802.11b+
Like the 802.11b and 802.11b+ adapters, the DWL-G520 uses a single 2.4GHz wireless frequency, eliminating the complexity of dualband networking. 802.11g's compatibility with existing wireless LAN standards means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 802.11g's speed when you mix 802.11b and 802.11b+ with 802.11g devices, but you will not lose the ability to communicate. The DWL-G520 is compatible with existing 802.11b and 802.11b+ devices such as the D-Link Air, AirPlus and AirPro family of products, including the DWL-520, DWL-520+, DWL-AB520 and DWL-120 wireless adapters, and the DI-714 wireless router.

Easy Migration to Higher Bandwidth
By maintaining compatibility with your existing wireless network equipment, this adapter lets you upgrade to a higher speed at the pace you want. The DWL-G520 and other 802.11g standard devices can be gradually added to your network, while the rest of your older network remains perfectly connected.

Wi-Fi Protected Access
Wi-Fi Protected Access is provided 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 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.

802.1x Authentication Compatible
The DWL-G520 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.

Pre-Shared Key
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 DWL-G520 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-G520, you will automatically receive a new key every time you connect, doing away with the inconvenience of manual WEP key input.
