Just got the PS4 today. It had a lot of trouble finding my wi-fi network at first. Later, when I finally got it to connect to the network, it has been able to download things, but at very very slow speeds--and the connection keeps dropping out and coming back. If I go to "test connection", half the time it will connect immediately, much of the time it will connect slowly, and sometimes just won't connect at all.
This is preventing me from playing one of my games, as it requires a constant internet connection to play. (Overwatch.)
No other devices in the same room have this problem--only the PS4. Any idea what I can try here?
