where do they need you to clone it too?

Their modem will only work with your ethernet card, so you will have to clone its MAC to the router. Should be an option for it in the routers' configuration.

Our isp requires us to enable the mac address cloning. My router is linksys wrt54g.

where do they need you to clone it too?

ISPs do this to make sure there aren't any unauthorized connections to their network. You have to set your Router to clone your computer's MAC address, if you have already connected your computer straight to your modem.
