i've had my PS3 for nearly 3 weeks. i've been trying to get online with it but haven't been able to. it won't link into the same signal my wii is linked into. when i try it says it works but needs an update. when i try to update it says i need internet to update. any help? P.S. i know the internet signal works because i can use the internet perfectly on my wii. in fact i'm making this through the internet channel.
