Connecting a second device to my wifi, need to find my Network Security Key

[TO1959]

Hi all, I got a laptop for Christmas. Trying to set up internet and my laptop is asking me for a network security key.  I've tried several numbers and none of them work. Any clues on where I can locate this?

Thanks for any repies

Well you didn't give us much info like router that you have, are you connect to an extender, etc.

you can always hardwire into whatever device you're using to log into its gui and access it. this avoids needing the wireless. 

here's an article on change the router ssid/password. You don't need to change it but it'll get you to the screen to view them.
