As a guide, a minimum connection speed of 2Mbps is recommended. To find out your upload speed, please check with your network service provider.

Hints for improving your network connection:

• It is recommended that you use a LAN cable to connect your PlayStation®4 console to the network.
  
• If you are using a Wi-Fi connection, place the PS4™ console and the router closer together, and make sure there are no obstructions between them.
• Other devices on your network might be using a large amount of bandwidth. Wait until they are finished before trying again.
• Check the connection status of the PS4 console in Settings > Network > Test Internet Connection.
