macbook wifi card not working

macbook wifi card not working

I have a macbook 1.83ghz.
I installed snow leopard and the wifi crashed (?)
It was barely functioning before, but now all it can do is detect names of
routers.
I haven't done anything as i don't know what to do.
How do i run a diagnostic before i have to buy a new wifi card?
