Windows Vista Network connection issues

[Ice18]

I'm home for the holidays and trying to connect to the new router. It has a different password than the old one, and after many attempts at guessing the password(nobody was home when I got here) it tries to connect without asking me for a password. It never connects successfully, as the last password entered was the wrong one.
Is there any way I can get it to ask for the password again?

My laptop is a Toshiba with Windows 7 home premium installed.

Ice18, hello and welcome to the forums.
Try this.
Open the network and sharing center and in the left column choose "Manage Wireless Networks" this should provide a list of any previous wireless profiles that you've created in a list. Select the problem profile and remove it. Use the add button to setup a new one.
