If you’re having problems with your PlayStation 4’s WiFi, there are a few things you can do to troubleshoot the issue. First, make sure that your router is up and running. If it isn’t, you may need to update it. Second, try resetting your PlayStation 4. This will fix any issues that may have been caused by a corrupted firmware or by a power outage. Finally, if none of the above help, you can go to your PlayStation 4’s support page and file a support ticket.
