unknown network security key

I cannot connect to my wireless router. Program wants a network security key, which I do not have and do not remember setting. How can i reset this so i can use my wireless on my laptop at home? Thanks.

Is this your router?
What is the make and model of the router?

Yes. It is a Linksys G router. I spent an hour chatting with them on Saturday and found the security key in the setup files. I have installed two systems like this before and never had a problem. It appears Vista picks up this key during the setup. Whereas, XP did not. Thank you.

Glad it worked out for you.
