Despite agreeing wireless could cause some issues, it's not the problem. I have my ps4 connected through cable but, even when I had it in a wireless (in ps3) mode I could play fifa 10 and almost every game run flawless whereas PES it's the same laggy crap every year. I even tried playing last year fifa via wireless, and then PES via cable, and guess what, PES was laggy 50 % of games whereas FIFA 90% run very good. I don't mint a little input lag but this year some games in PES are a mess, stuttering and 2 second I put lag sometimes it's a mess, specially in myclub. In online divisions it's much better but not flawless as it should be nowadays with the connection speed people have, and the netcode knowledge...
