I just picked up a 60gb PS3 last night. I also have the Xbox360. I have the DLink DGL-4300 router. Can anyone tell exactly how to set up the PS3 to go online? Thanks

 

How is the X-box connected?

The PS3 has built in Wi-Fi. Simply go into Wireless setup and connect to your router. I have mine configured with encryption so you will have to enter the same key you created on the Router.

 

if you don't want to fiddle with the wifi, just connect it like you do with the xbox 360 (via ethernet)
or do what ashburner said

 

I was able to figure everything out,thanks.
