I thought I had disabled that WiFI on Power Saving mode thing but it was checked so I'll check it out (Edit: Didn't make a difference). Router is great, Vita is on max bars, I'm about 5 feet away from the PS4, and 20 feet away from the router. But I do have PS4 connected wirelessly to the router. I suppose I could get a powerline adapter. Worth a shot.
I don't know man. I mean, I really love a lot of things about the PS4. I love that it's so powerful, the OS is fast and has a good amount of features, it's social, sharing/streaming is a breeze, and with Sony's first party studios, the outlook on games is healthy. But Remote Play was one of my biggest features; you and others probably know it was one that I was most hyped about, so I guess that's why it stings so bad that it's not what I hoped it would be.
