Yes. Our rKade is always online and will require an active internet connection to play, update and install games. As a guide, a minimum connection speed of at least a 2Mbps is recommended. To check your upload speed, please check with your network service provider.
To improve your connection, try using an Ethernet cable to directly connect your PS4™ to your modem or router. If you are using a Wi-Fi connection, place the PS4™ 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. Pause, cancel, or wait until streams / downloads finish and try connecting again.
You can test your internet connection here.
