There are a few potential causes for why your PlayStation 4 may not be connecting to the internet. One possibility is that your router is not compatible with the PS4. Another possibility is that your PS4 is not properly configured. If you have any of the following symptoms, it may be worth checking to see if they are related to your PlayStation 4’s internet connection: - Your PS4 does not show up on any of your network adapters - You cannot connect to the internet from any of your devices - Your PS4 says it has been disconnected but comes back online after a few minutes - You cannot play games or watch videos on your PS4 if you have an active subscription to PlayStation Now If one or more of these symptoms applies to you, then it may be worth trying out some different methods of connecting to the internet, such as using a modem or using an ethernet cable. If none of these methods work and you still have trouble connecting, then you may need to call Sony customer service and ask for help.
