• In Windows XP, go to Start>Control Panel>System>Hardware Tab> click on the Device Manager
Tab> click on Network Adapters> double click on D-Link AirPro WUS-B12 Wireless USB Adapter>
make sure that “This device is working properly” is displayed under Device Status under the General
Tab. (Please refer to Checking the Installation of the Drivers for the Wireless Adapter in the
Networking Basics section of this manual for more information.)
• If the device is not working properly and a yellow exclamation mark is displayed, then there is probably a
resource conflict. In this case, make sure the computer system has a free IRQ and if necessary, uninstall
the drivers, restart the system, and repeat the driver installation procedure.
Troubleshooting (continued)
4. The wireless client cannot access the Internet in the Infrastructure mode.
• Make sure the wireless client is associated and joined with the correct Access Point. To check this
connection: Right-click on the Networking Icon in the taskbar> select View Available Wireless
Networks. The Connect to Wireless Network screen will appear. Please make sure you have selected
the correct available network, as shown in the illustrations below.
• Check that the IP Address assigned to the wireless adapter is within the same IP Address range as the
access point and gateway. (For example: if one computer has an IP Address of 192.168.0.2, the other
computers should have IP Addresses that are sequential, like 192.168.0.3 and 192.168.0.4. The subnet
mask must be the same for all the computers on the network.) To check the IP Address assigned to the
wireless adapter, double-click on the Network Connection Icon in the taskbar > select the Support tab
and the IP Address will be displayed. (Please refer to Checking the IP Address in the Networking
Basics section of this manual.)
If it is necessary to assign a Static IP Address to the wireless adapter, please refer to the appropriate section in
Networking Basics. If you are entering a DNS Server Address, you must also enter the Default Gateway
Address. (Remember that if you have a DHCP-capable router, you will not need to assign a Static IP Address.
See Networking Basics: Assigning a Static IP Address.)
