If your PlayStation 4 disconnects from WiFi, there are a few things you can do to keep it connected. First, make sure your PS4 is connected to the same network as your router. If you’re using an Ethernet cable, make sure it’s plugged into the PS4 and into your router. If you’re using a wireless connection, make sure your PS4 and router are both on the same wireless network. If that doesn’t work, try resetting your PS4. To do this, turn off your PS4 and wait 10 seconds before turning it back on. Once it’s turned on, press and hold down the power button until the blue light starts blinking slowly. After 10 seconds, release the power button and wait for the system to boot up normally. If all of those methods fail, you may need to call customer service for help connecting to WiFi. ..
