I just purchased a belkin prepmium CAT5e networking cable and plugged it into an internet wall jack and hooked it up to my ps3 and the connection won't work. Does it have to be hooked up to a router? Is a CAT5e cable the same as ethernet? or will I need to buy a different cable?

What is at the other end of the wall jack connected to?
A Cat 5e cable is an Ethernet cable.
That wall jack needs to be connected to something at the other end...
You probably have a patch panel somewhere and hopefully labeled, but this corresponding patch panel port needs to have a short patch cable plugged into your modem or router, Or into a switch plugged into one of those devices
