Complete novice needs help. Just bought a Wireless G notebook adapter and a Wireless G ADSL Gateway. Me and the missus have a card in our laptops. Ive set it up and its working but I have no security to stop someone having a peek or logging on to my netwrok. Can anyone give me step by step advice an what button to press etc? Ive read the manuals but its a little bit too technical. Thanks in advance. My missus is a little worried we aint protected.
