In general, if you cannot connect the PlayStation to the Internet, you can try some of these solutions:

  • Check in order to see if the PlayStation Network is online
  • Determine if the other devices can connect to the internet
  • Change the connection of the PS4 to the router
  • Re-enter the Wi-Fi password of the PS4
  • Change the DNS settings of the PS4

For everyone who can get online but cannot access the PSN, the first step that you have to do is to make sure that it is online. You can visit the PSN Network Status page and see if the status is green. If it is down, your only option is to wait for a while for the issue to be solved.

If the PS4 that you own is facing a hard time connecting to the internet, you can try to narrow down where the issue is by determining if the issue is related to the PS4 or to the Wi-Fi network. To do so, you can check to see if the other devices on your place such as tablets and computers can connect. Another thing that you need to make sure is the devices that share the same connection are working. For instance, if the PS4 is connected to the router with a wired Ethernet cable, then you can plug a computer into the router as well. In case the PS4 is using Wi-Fi, then you are recommended to connect to Wi-Fi with the phone and see if it works. If the other devices that you have also cannot connect, it is the perfect time to shut down the modem or the router and wait several minutes before you turn them back on. If it still does not work, you are encouraged to contact your internet service provider for help.

If you think the issue has something to do with the password, you can try re-entering it on the PS4. First, choose Settings. Then, choose Network and choose Set Up Internet Connection. Next, choose Use Wi-Fi. After that, choose Easy. Finally, select the Wi-Fi network, enter the password, and wait for it to connect.
