I thought the same thing happened to me last week and it took me about 4 days without being able to play, I could use the internet browser of the console, for which the internet had, but I could not log in to the PSN ... After giving a thousand laps to the problem, I opened the ports of the router and nothing ... I could not log in from any device (mobile application, PS3, etc) if I connected to the wifi at home, but if I did with the data of my If I could, and from another friend's house, it worked, I talked to my internet provider and I told them my problem, they told me they were having a lot of problems with IP (not my home, but with what they have to connect me), they changed it and it's already solved!
