My set up is cable internet where it goes from the wall to a modem and then to the PS3 with an Ethernet cable. Everything was fine with my PS3 until Tuesday. That was when my cable company disconnected my cable and internet by mistake because the technician shut off the wrong apartment. After 3 days I had a Technician come out and reconnect my cable and internet. The internet works just fine on my computer. But when I connect my PS3 to the internet, it will seem connected for about a minute, and brings up the friends list sometimes. But if I try to go to the PSN store, or go online with a game, it logs me out immediately with the error code 8002AD23. I contacted both my cable company and Sony and neither could give a solution that worked. I've tried every solution I found online and it didn't work. This is too much of a coincidence that the problem started after the internet service was reconnected after being off 3 days. Anyone experienced this PSN problem before where you have perfect internet on your computer but it won't stay connected to PSN?
