1 Introduction
Thank you for purchasing the 802.11g USB XRTM Wireless LAN USB Adapter. The USB XRTM
architecture improves wireless transmission over long distance and fully supports the MIMO XRTM
technology which enables you to connect to wireless networks at farther distances than before. The
adapter has one external and one internal antenna, designed with antenna diversity in receive and
transmit to maintain high-data rates at farther distances. Not only the connection distance is enhanced,
but also the “dead spots” in the network will be reduced. In addition, the adapter remains backward
compatible to 802.11b and 802.11g. When the adapter is connecting to the standard 11g or 11b APs or
Routers, it can perform much better than standard clients.
This adapter 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
adapter is connecting to the Routers or APs with the proprietary feature, the wireless network will be
more effective.
For WLAN security issues, this adapter 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 adapter supports WPA2
function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption
Standard), which is a requirement for some corporate and government users.
When you use the devices such as Voice over Internet Protocol (VoIP) phones, televisions, VCRs and
MP3 players, how can you speed up the audio, video and voice data to pass through the wireless
network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a profile of the
IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data traffics by the
data categories to provide enhanced multimedia support. This adapter supports the advanced
technology for sure.
This adapter is cost-effective, together with the versatile features; it is the best solution for you to build
your wireless network.

program from the CD.
Note2: The following installation was operated under Windows XP. (Procedures are similar for
Windows 98SE/Me/2000/2003 Server.)
Note3: If you have installed the Turbo Wireless LAN USB Adapter driver & utility before, please
uninstall the old version first.
A. Insert the Installation CD to your CD-ROM Drive. Execute the “setup” program.
B. Click “Yes” to process the installation if you accept the license agreement.

C. In Windows XP, there is a “Windows Zero Configuration Tool” for you to setup the wireless adapter.
You can choose to configure the adapter through the Windows Zero Configuration Tool or the
Ralink Configuration Tool for the adapter. It is recommended to choose the Ralink Configuration
Tool for the adapter. Click “Next” to continue.
D. If you need the adapter to operate with better performance, please choose the “Optimize for
performance” to enable the Tx Burst mode. Or you can choose “Optimize for Wi-Fi mode” to let the
adapter run in standard wireless network.
