Change network password?!?!?!?

I cannot for the life of me find out how to change my network password I have a wireless router with internet wired to 1 pc and a laptop using wireless I have googled for hours and am frustrated with the whole process seems everyone believes you are able to just go to change password in user accounts but that has nothing to do with my wireless networks password I am only worried someone else has been using the internet



all help is appreciated and thanks in advanceChange network password?!?!?!?
XP

1) Goto Start/Run

2) Type in ';cmd';



Vista

1) Click the Start button

2) Type in ';command';



Once you are in the command prompt:

1)Type in ';ipconfig';

2) In your Internet browser type in ';http://'; followed by your default gateway (found in the command prompt)

***Example: http://192.168.1.1 (try clicking the link)

3) Login (search online for login info) Usually admin, password

3) There should be a link on the side somewhere. It should have several options like WEP, WPA etc.



Or you can hold the reset button on the back of your router to remove the password and allowing you to create a new one.

Maybe if you had mentioned not only your operating system, but the name of the network you connect with, you could get some help. These two items are needed in order to properly answer your question.
