After having a bunch of issues with my last wireless router, (a Belkin) I am starting to consider buying an AirPort Express. I have a couple of questions before I decide, though. Here's my situation: I only have 1 computer in my house (my iMac) and the only reason I want wireless is for my PS3. I hated using the Belkin, as it cluttered up my desk and annoyed me with it's crappy interface, had issues with it slowing my connection down considerably, etc. I unhooked it a few months ago and just put it in the closet. What I wanna do is just connect my ethernet cable from my cable modem straight into the AP Express, then just use AirPort on my iMac and the wireless on the PS3. Is this possible? Does the AP Express support WPA encryption? Just wondering because since it'd be my only means of connecting to the internet, I'd like it to be secure. I also may be purchasing an older laptop at some point (probably an iBook G4) so I'll need the wi-fi for that as well. I'm just not sure if what I want to do with the AirPort Express is possible, so any help will be greatly appreciated.
