I have a 20 GB PS3 and when i search for a network nothing shows up. But my computer right next to it has one and so does my sisters wii.
Ouch! i must have gotten lucky then, i have a 60Gig ^_^ yah as Auslander said, ur best bet for wire-less PS3 gaming is to get 2 routers and network them. or the other option would be to wait until they have more 60G models for sale in canada and exchange yours for a 60gig
For the 20gb PS3s, can you use a USB Network Adapter and plug it in one of the front USB ports to use on an existing Wireless Router in a residence??
see if this helps too - http://forums.afterdawn.com/thread_view.cfm/438511 http://forums.afterdawn.com/thread_jump.cfm/439900/2661025
Doing that is actualy very Hard and Complicated, because you need to Disable the DHCP sever and change the ISP adresses to intweract with each other and they would need to be connected via eathernet. A wireless bridge would be they way to make you network larger without to much trouble!
20gb dont have Wi-Fi just use the plain ethernet nothing wrong with it Id rather use ethernet then Wi-fi with my wii but cant etherenet is more stable but my neighbour has an unencryoted Wi-fi connection LOL! free net
