Microsoft has integrated, from Windows XP, the wifi auto-configuration service, baptized by the firm as "zero configuration". The first thing to do to use it properly is to disable the other wifi wizards so that there is no conflict.
How To Enable Zero Configuration on Windows XP
In order to work with the "zero configuration", the wireless service must first be activated from the startup. To verify this and modify it if necessary, go to the Start menu and then to Run. Here, enter the services.msc command. You will see a window with all local Windows services. In this list, look for the Fast Wireless Configuration service. Right click on this option and select Properties. Here you verify two things: first, make sure that the Startup Type is set to Automatic; If not, modify it. Second, verify that the Service State indicates Initiate. If not, click the Start button. After you have done this, click OK and close the open windows.
How To Enable Microsoft Windows Wireless Connection Manager
As soon as the wireless automatic configuration service is active, you only need to activate the network manager by Windows. To do this, go to Start, Control Panel, and then to Network Connections. Here, right-click on the Wireless Network Connection icon and then select Properties. In the window, click the Wireless Network Settings tab. At the top of this same window, check the Use Windows to configure my wireless network settings, then press OK to validate.
How To Connect to Wifi
In this part we will consider that you already have all the necessary elements for the configuration of the wifi network. In this case, SSID will be the name of the network, it may be visible (which will simplify the configuration) or hidden (in this case it is necessary to know it). The security key is the password to access the network. This can be a WEP key or a WPA depending on the configuration of your access point. You now have two possibilities: the network will be detected or it will not be detected. So, start by looking at the networks that are within reach of the computer. In Control Panel, right-click the Wireless Network Connection icon, then select Show Available Wireless Networks. A list of Wi-Fi access points will be displayed within the computer's reach. If a Windows message appears saying you cannot configure this connection, you may have forgotten some of the steps described above.
If the network is detected, perfect. This will simplify your task: double click on your network. After a loading time, a window will prompt you for the network key. After entering your password, click Login. After a new charging time, the range window will reappear, indicating that you are connected to the network. You can now close all windows and start browsing.
If the network is not detected, you must manually add a configuration profile to Windows XP. Start by closing the window. Then right-click the Wireless Network Connection icon, then select Properties. Go to the Wireless Network Configuration tab. At the bottom of the page click Add. A window will appear asking for the SSID (the name of the network). Then mark Data Encryption and select WEP or WPA according to your settings. After you have entered the key, click OK to validate and OK again. Now you're connected. You can now close all windows and start browsing.
