As of Saturday around 12pm cst I was unable to sign in using my playstation network account on any device. Everything was working just fine the night before around 3am cst. SO this issue occurred within a 5-8 hour time frame. I've talked to a PSN supervisor and an AT&T supervisor, even made a 3 way call and it's just pretty much one blaming the other the entire time. I know about routers and how they work as well as IP's and all with firewalls. We've pretty much went though all types of troubleshooting from opening ports to even switching routers on AT&T technician when he came. But still same issue (ACCESS DENIED) can anyone possibly help? Will it work if I get a new router that's nowhere near the same model as the one I have, because they just switched it with being the exact same model as before. IP changed and still same issue.
