1 Introduction

Thank you for purchasing WLB5254USB-802.11g Turbo Wireless LAN USB Adapter. This USB adapter is
designed to comply with IEEE 802.11g Wireless LAN standard and easy to carry with the Mini size. It is
suitable for any Laptop or Desktop computers.

WLB5254USB supports higher data throughput than the IEEE 802.11g standard (up to 54Mbps). It supports
specific ways to increase the data transfer rate at a time; compress the data and decrease the waiting time to
send the next data to the Routers or APs. This feature is called Turbo Mode. When the adaptor is connecting to
the Routers or APs with the proprietary feature, the wireless network will be more effective.

For WLAN security issues, this adaptor supports 64/128-bit WEP data encryption that protects your wireless
network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that combines IEEE 802.1x
and TKIP (Temporal Key Integrity Protocol) technologies. Client users are required to authorize before
accessing to APs or AP Routers, and the data transmitted in the network is encrypted/decrypted by a
dynamically changed secret key. Furthermore, this adaptor supports WPA2 function, WPA2 provides a stronger
encryption mechanism through AES (Advanced Encryption Standard), which is a requirement for some
corporate and government users.

WLB5254USB is cost-effective, together with the versatile features; it is the best solution for you to build
your wireless network.
