6. Troubleshooting

This section addresses common issues you might encounter with your D-Link DIR-615 router.

6.1 No Internet Connection

• Check Cables: Ensure all Ethernet cables are securely connected to the correct ports (WAN to modem, LAN to computer).
• Modem Status: Verify that your modem is working correctly and has an active internet connection.

6.3 Slow Network Speed

• Channel Interference: As mentioned above, try changing the wireless channel.
• Firmware: Ensure your router's firmware is up to date.
• QoS Settings: Review QoS settings to ensure they are not inadvertently limiting bandwidth for certain devices or applications.
• Device Overload: Too many devices actively using the network simultaneously can reduce overall speed.

6.4 Resetting to Factory Defaults

If you encounter persistent issues, you may need to reset the router to its factory default settings.

1. With the router powered on, use a paperclip or a thin object to press and hold the Reset button (usually located on the rear panel) for about 10 seconds.
2. Release the button. The router will reboot with factory default settings.
