Welcome to the community I'm sorry to hear you're unable to connect your PS4 to the hub over wireless.
What exactly is happening when you attempt the connection? Are you being prompted for the wireless network password to connect? What happens after you enter the details? Do you receive any error messages to explain why this hasn't work? Are you experiencing issues with any other devices via wireless?
Let me know a bit more info if you can and I'll do what I can to help.
