using a notebook computer) and click ‘Rescan’ 
button for few more times. If you can find the 
wireless access point or wireless device you

point or wireless device is located. 

Nothing happens when I click 
‘Launch Config Utility’ 

1.

 

Please make sure the wireless network card is

1. Click ‘Connect’ for few more times. 
2. If the SSID of access point you wish to connect 

is hidden (nothing displayed in ‘SSID’ field in 
‘Site Survey’ function), you have to input 
correct SSID of the access point you wish to 
connect. Please contact the owner of access 
point to ask for correct SSID. 

3. You have to input correct security key to 

connect an access point with encryption. 
Please contact the owner of access point to 
ask for correct security key. 

4. The access point you wish to connect only 

allows network cards with specific MAC 
address to establish connection. Please go to 
‘About’ tab and write the value of 
‘Phy_Addess’ down, then present this value to 
the owner of access point so he / she can add 
the MAC address of your network card to his / 
her access point’s list.
