if you havent see this, try this and see if it works.. its already helped others, its just a posible quick fix.
i can play BF4 and CoD after doing this. If you call sony they will have you try this. and if it dont work they will tell you to try your ISP for port forwarding.

You guys are pretty rediculious, You realize you have the early version of the ps4 and its network. There are going to be issues get over it, if you didn't want the issues then you should of waited. The second thing you need to realize is a bunch of people are getting they're ps4's for xmas so sonys network is getting hammered. Stop acting like sony's network is the only one having issues, the xbox one is having just as many issues and more.
I mean when I pay a lot of money for something I expect it to work. They clearly did not budget conservatively for this..it is a rule of business to always allocate more resources (when they are available) than are necessary when budgeting..
I'm having error codes like NW-31448-0 while trying to check my trophies, profile, and friends. I also cant play Blacklight Retribution. Yesterday my PS4 crash while playing BF4 Campaign after that im getting errors. Just now my profile, trophies, and friends list load up but i receive a notification "Sony Network is currently busy" and I cant play online games.
I'm not complaining, I'm just letting Sony know about the problems we are having which looks really bad. I hope they'll fix this soon. We are paying for onlinesevice now with the PS4 and I'm expecting improvement in our online features for the PS4.
My experience with PS4 so far is not that good compared to the PS3. I got my PS4 since launch and I also encountered some problems like my PS4 is shutting off by itself.
