network connections

Hi I am having problems connecting my childrens desktop to my wireless network.Router is Belkin Wireless G modem. I have connected my desktop and wifes laptop both running vista but cannot connect childrens Advent T11 desktop running XP. Belkin say everything is ok I just need to turn on my wireless card in the Advent T11 running XP but I dont know how. The pc tells me that it cannot find a network.

On many laptops, there is a physical switch to turn on/off the wireless. It may be a key combination, e.g. Fn + one of teh F keys, or it may be a slider switch, usually near the wifi light.

PC specs are listed here:

This seems to be a desktop. If you cannot see a wireless signal have you tried pulling the PC out from under the desk or cupboard etc and allowing the antenna to 'see' the Belkin router?

Also check within the Device Manager that the wireless card is enabled and has a driver installed.

There may be a Creatix Wireless application running in your system tray - have you tried to use it? Otherwise you will need to ensure the Windows Wireless Zero service is running.

Which Service Pack for XP do you have applied? Earlier releases were not so good with wireless. You may want to download and install Service Pack 3.

If all that fails then check if your router's encryption is compatible with the wireless card in your kid's desktop. If your router is outputting WPA-2 but your wireless card can pick up only WEP then they are not compatible and won't see each other.
