I have an new laptop and I can not get it to accept my password to access the internet. I already have another laptop which is windows xp and this is connected fine. The new laptop finds the router but will not let me accept my password and allow me to connect to the internet. I have a speedtouch 580 router. Is this because I can not use a xp and a vista computer for the speedtouch 580? Please help as this is a christmas present!!
