Can only get local connection with apple router

I recently got a vista 64bit computer and everything works fine except i can't seem to connect to the internet thro my apple router. The router is fully up to date and works great with my windows xp computer. I can connect to the router but it is only a local connection with no internet, in the network and sharing center it stays on "identifying" I've tried updating the router and my computer aswell as rebooting my router and modem. IF anyone knows of a solution for this problem please let me know. thanks
