You can’t make a connection to your WiFi network because the wireless networking icon or properties dialog box does not appear.

I’m offer you a few solutions:

Windows XP Compatibility
Your problem may be that your wireless network adapter is not compatible with Windows XP. To check whether it is compatible, check the Windows Hardware Compatibility List (HCL). When you get to the site, click See the Windows Catalog, then from the page that appears, click the Hardware tab. Next click Networking and Modems, and click the Wireless Devices link. Browse the list, which is alphabetized by manufacturer, to see if your wireless card is listed. If it’s not listed, there may be a conflict with XP that will not allow it to run, although you can try the next steps in this recipe to try and get it to work.

Hardware Compatibility
There may be a conflict between routers and wireless adapters bought from different companies. In theory, all WiFi equipment, regardless of vendor, should be interoperable. In practice, that is not always the case. Buying all hardware from the same manufacturer lessens the likelihood of problems.

Update Latest Driver
The problem may be an outdated driver. Visit the web site of the manufacturer of the adapter, check for the latest driver, and download and install it according to the manufacturer’s instructions. After you install the new driver, restart your PC and see if it can now make the connection.

Wireless Zero Configuration
In order for your PC to automatically connect to a wireless network, the Wireless Zero Configuration service must be running. If it’s not enabled, XP won’t automatically make the connection. To make sure that it is, select Start, Run and in the Open box, type services.msc at a command line and press Enter. This runs the Services Microsoft Management Console. Scroll down until you see the Wireless Zero Configuration entry. The status should be Started. If it’s not, right-click it, choose Start, and exit the console. XP should now automatically search for and connect to your wireless network.

From the Device Manager, you can check the status of your WLAN drivers to make sure the device is working properly. If the Device Manager shows a yellow circle and an exclamation point next to your wireless adapter, then your wireless adapter may not be properly installed.

Right-click the adapter in question, select Properties, and then look at the Device Status box from the General tab to see that the adapter is working properly. If necessary, select the Driver tab in the Properties dialog box to access controls that let you uninstall or update the
driver.

If you see a red X by your wireless adapter, then the device is either disabled or your system can’t recognize it. Right-click the adapter and select Enable. If this doesn’t eliminate the red X then you may need to replace your wireless adapter.
