There are a few potential causes for your PlayStation 4 not connecting to your WiFi. One possibility is that your router is not compatible with the PlayStation 4. If you have an older model, it may not be able to handle the new PS4’s faster speeds. Another possibility is that your PlayStation 4 is not properly configured for WiFi. You might need to update your firmware or change some of the settings on your device. If you’re still having trouble, you can call Sony customer service and they will help you troubleshoot the issue.
