Yes I do, have done for a while. It works fine most of the time, only glitching for a second or two at its worst, and that's at Full HD on high frame rate. But my router died recently and was replaced so I'm on a new network, which I didn't think much of at the time. But then Remote Play started glitching and losing the image for several seconds at a time, and jumping through all of the resolutions available, or just disconnecting altogether. Sometimes it would look like I was racing in the original Gran Turismo, the image was so pixelated.
The problem is my old router produced two seperate networks for each frequency - 2.4ghz for b/g/n and 5ghz for AC, but the new one just produces a single network and manages the bands automatically, on top of the Playstation choosing the frequency automatically at its end of the connection. Apparently you have to go into Network Setup on the PS4, choose Wifi as if you were going to create a new connection, and then there's an option to press the 'Option' button on the controller to bring up a menu of options, the single option available being to alter which frequency the wifi connects with. I do wonder about Sony's UI design sometimes....
