Tracking debugs with timestamps is a nice start. Good suggestions about watching band, roaming and spectrum analysis is also important. I might go and swap out the nearest AP to the PS4 with a new or known good, just to take that out of the equation.

We use Aruba. I realize that like VoIP gaming is (typically) UDP and bufferless. Any minor imperfections are magnified with gaming and voice.
