In addition to offering faster data transfer speeds, this card also provides the newest, strongest, most advanced security features available today. For home users that do not incorporate a radius server in their networks, security is provided in a convenient, automatic way (when used in conjunction with other 802.11g products). No longer will you have to frequently input a new WEP key to execute security operations. 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. The DWLG520+ provides a stronger network security with 64, 128 and 256-bit WEP data encryption.
