I have a notebook with windows 7 installed however PS3 media does not work. I looked it up on the internet and found a couple of issues related to the AT&T therefore nothing really specific.
There is a configuration on the U-verse router, "Allow all applications (DMZplus mode)", that allows all inbound traffic is excepted traffic and all unassigned firewall ports are opened for that computer but still not working.
Anyone has faced the same issue? Any advice?
