For the ultimate experience during PlayStation 4 Remote Play, we recommend that you set up a wired connection via a LAN cable to the same network as your PlayStation 4 system. This will give you the fastest and most stable connection.
Wired connection example
A) Router
B) A cable modem or DSL modem.
C) A connection to the Internet
If you would like to try a wireless set-up, ensure you follow these handy hints:
Wi-Fi network example
The diagram below shows a sample Wi-Fi network setup. Actual connections might vary depending on the types of devices you use for the access point and modem, and on device settings.
A) A wireless access point or a wireless router
B) A cable modem or DSL modem
C) A connection to the Internet
When an Internet connection is required, your system automatically searches for nearby wireless access points.
To set up the connection with a wireless access point, go to a location with an access point that you can use, select (Settings) > [Start] > [Network] > [Wi-Fi Settings], and then select the access point you use. You will need the information to connect to the access point (the SSID and security information such as the WEP key or WPA key).
After your system has connected to an access point one time, it will automatically connect to the access point in the future.
