Installation and Configuration
a) Network Card Installation
Please follow the following instructions to install your new wireless network card:
1. SWITCH THE COMPUTER OFF, remove the cover and insert the wireless network card into an empty
PCI slot of your computer.
install the antenna on the wireless network card, and make sure the antenna is securely installed. To improve
radio reception, please adjust antenna to the position.

The following message will appear on your computer, click ‘cancel’.

Wireless connection is established, good signal reception.
Wireless connection is established, normal signal reception. Wireless
connection is established, weak signal reception.
LConnection is not established yet. •■Wireless network card is not
detected.
There are two ways you can configure your wireless network card to connect to wireless access point:
using the Ralink configuration utility and using built-in windows zero configuration utility.
2.2.1 Using Ralink Utility
Please follow the following instructions to use Ralink configuration utility to connect to wireless access
point.
1. Right-click the Ralink configuration utility icon located at lower-right corner of computer desktop and then
clicks ‘Launch Config Utility'.
Ralink setup utility (RaUI) will launch, and begin to scan for all wireless access points
automatically.

3. RaUI consists two parts: Menu and setup area. You can select a setup function (Profile, Network, etc.)
from menu, and corresponding setup items will be displayed at setup area.
Some function includes more information, and can not be fitted in setup area. In this case, you
can click 'More / less’ button to expand the setup utility window, to display more information:

You can click More / Less button again, and setup utility window will resume to its original size.
Tip: If a setup item requires more information to complete the setup
procedure, the setup utility window will expand automatically.
There are two kinds of wireless connection mode: Infrastructure and Ad-Hoc. Infrastructure mode is
used by wireless access points, which is able to establish wireless connection for you and other

2-2-1-1 Scan for Other Wireless Devices
wireless I wired network clients.
Ad-Hoc mode is also know as ‘point-to-point’ mode, and in this mode, wireless devices such as
computer or PDA will not be capable to establish wireless connection with more than one wireless
device, and is suitable for establishing a one-to-one wireless connection between two wireless devices.
Before you can connect to any wireless access point or device by infrastructure or Ad-Hoc mode, there
two things you must know:
a. Wireless device’s ‘SSID’ (Service Set IDentifier, someone will call it 'access point’s name’).
You can scan for the SSID of other wireless devices nearby, but if the SSID of the wireless
device you wish to connect is hidden, you must know exact SSID before you can establish
connection with it.
b. If the wireless device you wish to connect uses encryption, you must know its encryption
key.
Please launch Ralink setup utility and it will scan for wireless access points near by:
Scan results will be displayed here, please check if the wireless device (access point or another
computer) with the SSID you wish to connect is shown here.
Scan result includes 6 types of information, they are:

A: The SSID (Service Set Identifier) of wireless device. If nothing is displayed here, it means the SSID
of this wireless device is hidden.
If a ^ symbol appears in front of the name of wireless device, means you’ve established connected
with that wireless device.
B: The type of this wireless device and the channel number of this wireless device.
^ Means this wireless device is an access point
Means this wireless device is a computer (Ad-Hoc mode, point-to-point connection) C The wireless
standard supported by this access point is displayed here.
‘n’for 802.11n fl_, ‘g; for 802.11g I ， and ‘b’for 802.11b 8.
WPS icon ** will appear when the access point supports WPS. If the access point uses encryption, a key
icon will appear.
Note: When the access point supports WPS and WPS icon is appeared, you will not see the key icon °
here even through the access point uses encryption.
D Shows the signal strength of access point by percentage.
E Shows the bar graph of the signal strength.
If you can not see the access point you wish to connect here, please click Rescan button to scan for
access point again, until the one you preferred is displayed. You may have to click ‘Rescan’ for more than
two times before you can see the access point you wish to use here.
If you still can not see the access point you wish to use after clicking ‘Rescan’ for more than five times,
please move your computer closer to the location where the wireless access point is, or see instructions

in Chapter 4-2 ‘Troubleshooting’.
If you wish to see detailed information for a specific access point, please double-click on it, and you’ll be
provided with its detailed information.

There are 4 types of technical information:
General: Displays basic information about this access point, such as SSID, MAC Address,
authentication / encryption type, channel etc.
WPS: If this access point supports WPS (Wi-Fi Protected Setup), related information will be
displayed here.
CCX: If this access point supports CCX (Cisco Compatible extension), related
information will be displayed here.
802.11n: If this access point complies with 802.11n draft, related information will be
displayed here.
And here are descriptions of every setup item in setup area:
If the wireless access point you wish to connect is found, you can establish connection with it by clicking
‘Connect’ button. Instructions will be given as follow:
Item Name
