Secured wireless connection do have a password.
Not sure what your 'wireless access point' is. If it's your router, it can be found (and changed) in the router configuration screen in your browser. If it's managed by someone else, ask him.
It's same password you use in your wirelessly connected laptop, PC or game console.
I found the set up of this wireless lan going fairly well on my bluray player model bd1600 until I got to the on screen set up asking me for a pass word after choosing my access point which is a bsecured wireless connection. I did not know I even had a pass word. Any idea where I find this or any way to bypass?? Thanks, T.Cameron
