you didn't state if there was any type of WiFi encrpytion set up in the AP/WiFi Router. if there are make sure those key(s) are entered, also check in the device manager to make sure that vista hasn't turned off the WiFi card to save power. another thing you might try to even know that the WiFi card is up and running and the OS can see it, is a IPConfig /all, if both the wired and WiFi cards are working it will list the MACs, IPs, etc. If only the wired is showing up then you know that there is a driver problem, or Vista has turned off the WiFi adapter to save power. Also some laptops will auto shut down one connection when another is plugged in. I.E. wired is on so WiFi won't work or vice versa.
