PS3 Networking Problems.
Hello. I recently switched the networking service in my apartment from my Roommate's name to my own name. In doing so, AT&T had to take down the network for a few days for reasons that remain unclear to me. Before and after the switch, I used the same router, and now use the same network name and password.
Neither of my computers have had any problem with the adjustment, but my PlayStation 3 can no longer connect to the network. It times out on "exchanging key information."
Any ideas? I've tried Googling for help, and have had little luck.
I would try deleting the network connection and making a new one.
