The highly efficient 2.4GHz 802.11g/b Wireless Network PC Cardbus is designed to meet the needs of wireless clients who connect to 2.4GHz standard network products. With the Dual-Standard capability, this Wireless Network PC Cardbus automatically switches to the proper modulation, i.e. OFDM, CCK and etc., supported by one of the two standards, IEEE 802.11b or g(draft), that the corresponding wireless networking device is using.

The Wireless PC Cardbus offers unbeatable performance of data rates up to 54 Mbps for 802.11g(draft) and 11 Mbps for 802.11b, while maintaining wide range of area coverage.

Wireless network security is protected with standard WEP encryption and Wi-Fi Protected Access (WPA), and further enhanced with 802.1x authentication security. With drivers and utility available for most commonly used Windows OS including Windows XP, the setup and installation can be easily managed. The 2.4GHz 802.11g/b Wireless Network PC Cardbus is a truly solid-design networking device that provides you with the ultimate freedom of wireless networking anywhere


  • Fully IEEE 802.11g (draft) and 802.11b standards compliant.

  • Highly efficient design mechanism to provide unbeatable performance achieving data rate up to 54 Mbps for 802.11g (draft) and 11 Mbps for 802.11b with wide range coverage

  • Strong network security with 802.1x, Wi-Fi Protected Access (WPA) and WEP encryption

  • Auto-switch between the two standards, IEEE 802.11b and g (draft) that the corresponding networking device is using.

  • Driver/Utility supports most commonly used operating systems including Windows 98SE/ME/NT/2000/XP and Linux
