6. Troubleshooting

If you encounter issues with your D-Link DIR-655 router, consider the following troubleshooting steps:

• No Internet Connection:
  • Verify that your modem is working correctly and has an active internet connection.
  • Check all cable connections between the modem and the router, ensuring they are secure.
  • Power cycle both your modem and router: unplug them from power, wait 30 seconds, then plug the modem back in. Once the modem is fully online, plug the router back in.
• Slow Wireless Speeds:
  • Ensure your devices are within optimal range of the router.
  • Minimize interference from other electronic devices (cordless phones, microwaves) operating on the 2.4 GHz band.
  • Check for firmware updates for your router on the D-Link support website.
• Cannot Access Router Settings:
  • Ensure your device is connected to the router's network (wired or wireless).
  • Try accessing the router's web interface using http://dlinkrouter.local or 192.168.0.1.
  • If you forgot your password, perform a factory reset (see Maintenance section).
• Dropped Connections:
  • Adjust the router's antennas for better signal strength.
  • Ensure the router is placed in a central location, away from obstructions.
  • Check for conflicting IP addresses on your network.

7. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your router:

• Firmware Updates: Periodically check the D-Link support website for the latest firmware updates. Updating firmware can improve performance, add new features, and fix security vulnerabilities.
• Physical Placement: Place the router in a well-ventilated area to prevent overheating. Avoid placing it in enclosed spaces or near heat sources.
• Regular Reboots: Occasionally rebooting your router (unplugging it for 10-15 seconds and plugging it back in) can resolve minor connectivity issues and improve performance.
• Factory Reset: If you experience persistent issues or forget your router's login credentials, you can perform a factory reset. Locate the reset button (usually a small pinhole) on the router, press and hold it for about 10 seconds using a paperclip until the power LED blinks. This will restore the router to its original factory settings, requiring re-configuration.
