The ps3 gives me an error saying "connection to the access point could not be established, check the security settings for the wireless lan." It fails in the very beginning when running the connection test on the ps3, in that it fails to even obtain an ip address. The ps3 does see the ssid on the asus. I have manually entered the ssid and passphrase as part of many attempts to get it to connect. I gave it a static ip just as something to try, since it fails to obtain one on it's own.
I set up the engenius as a wireless repeater, so it's picking up my 2.4ghz N wireless network from the Asus. I have hard wired the ps3 into the engenius, and then manually entered all the same network settings as when trying to connect directly to the Asus wireless network. I still used the static ip, with the same ssid and same password, UPnP enabled. When hard wired into the repeater, these settings work, and I can connect with an NAT type 2, though my speed is halved due to connecting to the repeater. When I use all the exact same settings trying to connect wirelessly to network, it gives the error I wrote in the first sentence of this post.
It's seeming all the more likely that the Asus and the ps3 just aren't going to get along and I'm not going to be able to force them to either.
