I used to play wireless on my ps3 (as a whm) when I switched to wired big difference. You won't see it so delayed also I turn my music close to off to hear the sound. I know play on ps4 and tried turn5 with it visually its clearer and no delay at all and I'm playing wired. Only just got my ps4 last week.
I will admit that playing on ps3 for a whole year limited my game play and thankfully my fc was willing to work with my limitations to get me trough content. Like doing fights in very unorthodox ways to compensate for my ps3 limitations. Now I'm on ps4 and some fights I will have to relearn to do in the server standard way. You can clear t5-t6 on ps3 but you will need to play wired, HUD layout and name plates off is a must. And if you can't play wired try a wifi booster to get even stronger signal. Good luck
