I recently started getting the dreaded 8002AD36 error on my PS3 any time I was powered up and watching YouTube, MLB.TV or Hulu. It is one of the most annoying errors I’ve come across as it seems to pop up every 15 minutes or so and it pauses what you’re doing and tells you that you’ve been logged out of PSN until you click the login yet again.
I realized that the problem started for me right after I installed a new router, a Linksys WRT3200ACM so I knew it was probably related. After trying a variety of fixes I found elsewhere the only thing that fixed the problem was manually setting up port-forwarding for the ports that the PlayStation Network uses.
The ports that need to be opened are:
TCP Ports: 80, 443, and 5223 &
UDP Ports: 3478, 3479, and 3658
Once I manually opened those ports in my router the constant disconnecting of the PSN stopped and I was able to enjoy my PS3 again. For some reason the UPnP that worked on my old router settings didn’t work on my new router as I’d never had to set the manual port forwarding before.
I hope this tip helps you rid your machine of the 8002AD36 error!
