linksys hg200 adsl router modem

Please can anyone help, im going nuts over this.
i got this linksys gh200 adsl router modem from tescos.
it works fine, my two pc's get on the net fine, my xbox gets on line fine, but it stops both my ps2's from getting online.
i phoned linksys helpline & they told me i have to conifure the modem but i need the correct info to type into my modem config screen.
i can email a picture of the modem config screen if anyone needs it to help me.
if anyone knows the info please please help.
Thanks inadvance.......
