If you want to close the configuration utility, please click ‘Exit’.

Please note that if you stopped config utility by ‘Exit’ function, you’ll not be able to maintain the wireless link to the access point you wish to use. In this case, you can start config utility again by clicking ‘Ralink Wireless Utility’ icon from ‘Start’ -> ‘All Programs’ -> ‘Ralink Wireless’, as shown below.

2-2 Connect to Wireless Access Point

After the driver is correctly installed, it will try to connect to any unencrypted wireless access point automatically. If you want to connect to a specific wireless access point, or the access point you wish to connect uses encryption, you have to configure the wireless network card and input required parameters, to get connected to the wireless access point you wish to connect.

NOTE: In Vista, the network card will not connect to any unencrypted wireless access point automatically.

The current status of wireless connection will be displayed by Ralink configuration utility icon:

Wireless connection is established, good signal reception.

Wireless connection is established, normal signal reception.

Wireless connection is established, weak signal reception.

Connection 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.

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.

Setup Area

More / Less button

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.

2-2-1-1 Scan for Other Wireless Devices

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 wireless / 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 B C D E

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 WPS icon access point uses encryption, a key icon

, ‘g; for 802.11g , and ‘b’ for 802.11b .

will appear when the access point supports WPS. If the

will appear.

Note: When the access point supports WPS and WPS icon

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 ‘Troubleshoot ing’.

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.
