Dogs Rule on 18 August 2008
I wanted to know your router so I can try to find a setting which would allow your PS3 to connect directly to your router.
You can't use a USB network device on the PS3 (outside of Linux) since you won't have the drivers for it.
One option you have, if you truly cannot connect to your network directly, is to buy a second wireless router which would sit near your PS3 and be connected to it via an ethernet cable. That second router would then be configured to communicate with your main router.
