Re: my son tells me his PS4 connection is very mixed.ok and then lags. Can you help.
Welcome to the forum and sorry to hear your son is having trouble with his PS4.
We're going to need to know some more information about your setup. How is the PS4 connected to the hub? Is it over wired or wireless? If it's wireless I'd highly recommend having a gaming console set over wired.
It could also make a difference what games he's playing.
