I set up a wireless network using a D-link router about 2 years ago. I tried setting up my PlayStation 3 using that same network but it will not connect. I'm not sure if the WPA key I am using is wrong or if there's some other issue. Is there any way that I can check the WPA key that I am using to see if it's right? And if it isn't right and I can't remember the password, is the only solution to reset the router and have to re-establish the network?

Any help is MUCH appreciated!!
