It may be possible since the AirPort routers do not support UPnP natively that your PS3 is having difficulty establishing the proper communcation links for online gaming. This issue comes up with the Xbox 360 as well. The potential solution is one of the following: 1) Enable port mapping on the Extreme, 2) Configure the PS3 in a DMZ, or 3) Use another router that supports PPnP.

Just about all vendor models except Apple. I would suggest that you check out the PS3 Support site to find out what they list as compatible routers. Microsoft provides something like this for the Xbox 360.

Had the same issue(but with xbox). I tried everything...hardwiring, wifi, port forwarding, and even an express. Nothing worked, still nat was moderate. I did find a solution!!
Going off memory here....
1. You need to create a default host under the extreme in the utility app. I forget off the top of my head where it's at. I think it's under Internet/options. I created my default host as 10.0.1.100.
2. Then(in case) I opened the ports needed for xbox and where it says private IP address put 10.0.1.100.
You need to look up what ports ps3 uses on sonys website.
3.update the settings on airport and exit
4. Manually configure the ps3 either wifi or Ethernet. Enter the IP address as 10.0.1.100. Sub (mine) 255.255.255.0. Then the default gateway 10.0.1.1.
You should be good to go. Mine is open now all the time. You can find the default gateway and subnet mask in the utility app. You could also under the world picture in airport utility, grab the dns server numbers and manually plug those in as well. Hope this helps.
