How to find my own security key?

[dorothyratto]

am using my boyfriends router. I pushed the wrong button on Sunday. I lost every thing including the internet. I am trying to get back on the internet. It keeps asking for the network security key. I don't know what that is . I did'nt set this up. of course this is a different lap top.
