Security Key problem

[rdalpozz]

We are trying to set up our smart Tv with the wirless set up but each time we place in what we think is the security key it says wrong. I have checked all my documents and the back of the router but all I can find is the WPA passphrase. This is not working so I guess it is not the same thing. Help!!!!
