you may need to add the MAC address of you laptop wireles card into the config of your router. And if you have security setup on the router you will need to enter the routers security code (WEP key)
What make of router have you got?
Do your laptops see the router, you can tell this by looking in the bottom right hand corner by the clock (XP don’t know about Windows 7 or Vista)If you can see a picture of a computer screen with radio waves coming from it right click on it and choose “view available wireless networks” if you can see your router click on it and then click connect. Enter your WEP key and if everything is OK you should then be connected.
Any problems PM me and I’ll try and talk you through
