Then I would recommend providing some information about your internet service, as it is clear that this issue isn't widespread - if it were, you'd be reading about it in the headlines.
Who is your internet service provider?
What region are you in?
Are you on university/college internet?
What is your PSN ID?
What troubleshooting steps have you tried so far?
This same problem began with BF4 on my PS4. It turns out that when my cable company switched out my cable modem a few months back the modem it recieved from them had built in wifi and was also a router. This cause my physical hardware to be setup as double routered because with the old modem I already had a personal wifi router. I had my ps4 plugged in thru Ethernet port on my personal wifi router, so all I did was move the ether net plug to the cable modem router and this foxed my problem without having to configure port forwarding or setting up a static ip for my ps4!
