That and also is the router handing out DHCP address's?

It screams DCHP to me.

i checked my laptop out and it's set to using DHCP ..

I was pretty sure you would find the Mac set for DHCP as you say it works fine with other networks. Do you know how to check the WiFi Router? Can you get us a model number for that Linksys?

i don't know how to get that number for you ..
how can i get it ?? is it from network preference ??

You say it's a Linksys Wireless Router. There should be a label on it with the model number. What does the router look like? Color?
