I have an AE (Express) & APE (Extreme). Right now I have them joined, and I can listen to music through my home receiver via optical. Tonight I thought I would try to use the Ethernet port on the AE and I'm not having any luck. My PS3 will not obtain a IP Address. But when I connect it directly to the Extreme using the same cable it works just fine. Is it possible to configure the Express to work with the Extreme so that I can still use the optical port & have my PS3 connected to the Ethernet port? Any guides or help would greatly be appreciated.
