driver and Ralink WLAN Utility’, you can choose the configuration tool used to configure the wireless

network card here. It’s recommended to select ‘Ralink Configuration Tool’, which provides fully access

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

2-2 Connect to Wireless Access Point

There are two ways you can configure your wireless network card to connect to wireless access point: using

the Ralink configuration utility which comes with wireless card driver, 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

click ‘Launch Config Utilities’.

2. Configuration utility will scan for all wireless access points automatically. Scan results will be displayed

here, please check if the wireless access point with the SSID (the name of wireless access point) you

preferred is shown here.

If the wireless access point you wish to connect does not show here, please click ‘Rescan’ to try 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 sometimes.

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 3-2 ‘Troubleshooting’.

Here are descriptions of every setup items:

SSID

BSSID

Signal

Channel

Encryption

Authentication

Network Type

The Service Set Identifier of wireless access point or other network device. You can

think it as the name of access point of wireless device.

The MAC address of wireless access point or other network device. Unlike SSID, BSSID

of every access point or network device is unique, and will not be the same with others.

So you can identify a single access point or wireless device from others by BSSID, if

they all have the same SSID.

Shows the signal strength of access point or wireless device. Larger number means

better radio strength, which often means you’re not too far from that access point or

wireless device.

Shows the channel number that access point or wireless device uses.

Shows the encryption method that access point or wireless device uses. If the wireless

access point does not enable encryption, you’ll see ‘None’ displayed here.

Shows the authentication mode that access point or wireless device uses. If the wireless

access point does not require authentication, you’ll see ‘Unknown’ displayed here.

Shows the type of wireless connection. If it’s a wireless access point, ‘Infrastructure’ will

be displayed here; if it’s a computer or network device, ‘AdHoc’ will be displayed here.

Tips:

Wireless access point (Infrastructure) is a network device which acts as a bridge, to let

wired and wireless network devices communicate with each other.

AdHoc is another connection type. A computer or network device can establish a direct

wireless link with other computer or network device directly, without the help of wireless

access point.

3. Click the wireless access point or network device you wish to connect, it will be highlighted, then click

‘Connect’.

If the access point you selected does not enable encryption (The content of ‘Encryption’ field of the access

point you selected is ‘None’, you’ll be connected to this wireless access point within one minute. Please jump

to step 6.

If the access point you selected enables encryption, please proceed to next step.

4. If the wireless access point does not have SSID, you’ll be prompted to input it here. Please ask the owner

of wireless access point and input the exact SSID here, then click ‘OK’ when ready. If the SSID you

provided here is wrong, you’ll not be able to connect to this access point.

If the wireless access point you selected have SSID, please skip this step.

5. If the wireless access point uses encryption, you have to input WEP passphrase or WPA preshared key.

Please ask the owner of the wireless access point you want to connect, and input the correct passphrase

/ preshared key here, then click ‘OK’. If the value you inputted here is wrong, you will not be able to

connect to this wireless access point.

Authentication type is selected automatically, please don’t change it.

If the access point you selected does not enable encryption and does not require authentication,

please skip this step.

6. You’ll see ‘Connected <-> SSID’ (‘SSID’ is the SSID of the wireless access point or wireless device you

connected to) message displayed at lower-left corner of configuration utility, congratulations, you’re

successfully connected to the access point or wireless device you selected!

7. You can put the mouse cursor over the Ralink configuration utility icon, and the brief information about link

status and signal strength of current wireless connection will be shown as a popup balloon.
