Network key?

I had my network key changed for some reason, i can't remember why or when, but my internet works perfectly fine. My laptop connects wirelessly automatically. What I need to know is, how can I figure out the network key again? It was written down on a little paper somewhere, but I can't find it. I am the admin to my laptop, so theres no problem there. Or, do I need to go on the desktop to find the network key?Network key?

Or you can go into the config page on your WAP, and just change it to something you know / remember.Network key?
You need to get into your router's firmware-based setup by opening your browser and entering the router's IP address. (For Linksys routers it's 192.168.1.1). Enter the password you set for the router (or ';admin'; if you've never set a password). See your router's manual for details, especially if you've never gone into your router's setup before.



The network key should be displayed (and can be changed) in the wireless security section. You may need to look around a bit to find it, as it's different depending on the brand of router you have.
