Hey, I just wanted to throw out there that, for giggles, I tried hooking my PS4 up with an ethernet cable instead of going wireless, and it's now running for me just fine. I've been playing for more than an hour without being disconnected or even lagging. So, the problem may not necessarily be Square Enix's after all, maybe it's some kind of issue with Sony's system, or... or I don't know. But for me, that did fix the problem, even though needing to use an ethernet cable is a bit of a pain.
