BB Curve :: Can't Connect 9360 To Internet

I have a blackberry curve 9360 and I wanted to connect my blackberry to my home router while I'm at home, but away from the computer, so I did this:

-I went to Manage Connections

-I went to Wi-Fi Network

-My network at home, which is my saved network, shows up and I click on it

-instead of asking for a passcode even though it shows that my home internet is locked, it immediately starts trying to connect to my internet, and then says "Failed to authenticate against the network"

Since this happens ALL THE TIME, I went to "other ways to connect", then "Wi-Fi Protected Setup" and I see that the two options are "Press button on router" or "Enter PIN into router."So I clicked the first choice and it tells me to press the Wi-Fi Protected Setup button on my wireless router or its administration screen. That will probably get my internet working on my Blackberry?
