i've got the same error, and i find what it is:
PlayStation®Network - UPnP- NAT Type- functions configuration disappear in Internet Connection Test.
the solution is to find where in PS3 system files replace the "file" copyng from a working ps3 .
Please help us get on-line.
So far unchecking auto sign hasnt helped... I have been receiving this errorcode since lasr September. The worst part is they removed all my purchases and downloads pertaining to PSN. I've called SONY 3 times every call starts with,. operator: idk the errorcode, let me ask my supervisors or whateves. No solutions... ):
Hey, so for those who did all that stuff like setting time and date, and unplugging and unchecking, and still have no luck. I do believe I know the cause of the Errorcode. They were a few suggestions by Sony, which I finally got somewhere on here. So, errorcode 80010519 is due to your firewall settings/ (so they say) missing ports. Certain ports are supposed to be forwarded, but when I forwarded them, it did nothing. So after my 3rd call to Sony, and the first they mention my firewall, I decided to go and remove all firewall settings on my router. All that came up, is now, when I do a Internet Connection Test, all the options are up. Though, still, PSN chooses to fail, and when I log into PSN I still get 80010519. Maybe it specifically has to do with my router, but those who know how to remove their firewall settings (for a quick test to see if you can get on to PSN) may want to try this. I'd like to see if this works for anyone, cause if it does, I'm sure it has to do with my router. But yeah, also another suggestion was, if your wifi security is wpa-psk2 or something like that, there may be to much protection and you may need to lower the security. I have not tried that option yet
