WiFi Troubles please help

[corry20]

On my macbook pro I can't connect to a wifi network.I have Leopard.I see the network name I click on it and the circle spins for a little bit and stops.I have a ipod touch and it works fine with my connection and I have vista on my macbookpro and when I go onto that side it works fine no problems with wifi.Why can't I connect on Leopard?

The fact that it runs in Vista means that its not a hardware problem. Have your repaired permissions? You can also try deleting the network in your list to see if it has incorrectly saved a password.

The network I am trying to connect to doesn't have a password.How do I go about repairing it.

is there two networks in the same area with the same name? (name was left at the default "linksys" or "router")
