If it already says connected, then click disconnect first.

You can also do it from going to Control Panel, Network Connections, right click the Wireless network Connection and go to Properties, and go to the Wireless tab (I think it's called wireless...I don't have a wireless card around at the moment). There should be a list of networks toward the bottom, I'm fairly sure you can double click on those to edit the properties, so you should be able to enter the password there too.
