UPnP should be turned OFF on your router settings
Why I didn't check this board before pulling my hair out this weekend I don't know!
(Actually, I had family in town and was too busy to check).
In the end, I actually figured that out on my own. AND IT WORKS! Even got the FW to update to the latest.
Now, do I care that uPNP is disabled? The PS3 makes it sound like it's a big deal, and my life will be miserable. I'm embarrassed to admit that I don't understand, and don't know. What will I have to know in the future to make sure that software "plays nice"?
