How do i find my own security key for my wifi?

[Peter Herald]

I have had to re format vista and reload my WiFi. My internet connection using an ethernet cable to my LAN works ok but when the ethernet cable is removed and I click "connect" I am asked for my security key or passphrase. How do I find this information or preferably remove the request for it?
