Basically my problem, is that I have a game room that I just set up with my PS3, but this room, is separated from my router by a lot of walls, so the connection to online play on the PS3 is really crappy. What I was wondering, is if it would be possible to buy a new airport extreme/express, and create a new network entirely on that. If this is possible, what do I need to do to get a new network up and running. Another question I have is if the airport express can have guest accounts running on it. The reason I want this, is because I want to use games online with my DSi, which only has WEP supported wireless access, and I would rather use the more secure WPA2 for my PS3, without having to change the security type every time I used my DS. Thanks for any help provided!
