Troubleshooting
This section addresses common issues you might encounter with your D-Link DI-624 Wireless Router.
No Internet Connection
- Check Cables: Ensure all Ethernet cables are securely connected to the correct ports on the modem, router, and computer.
- Modem Status: Verify that your Cable/DSL modem's indicator lights show a stable internet connection. If not, contact your ISP.
- Router LEDs: Check the WAN LED on the DI-624. It should be lit to indicate a connection to the modem. The WLAN LED should blink to indicate wireless activity.
- Reboot Sequence: Power off your modem, then your router, then your computer. Wait 30 seconds, then power on the modem, wait for it to stabilize, then power on the router, and finally your computer.
Slow Wireless Speed or Dropped Connections
- Interference: Other wireless devices (cordless phones, microwaves, neighboring Wi-Fi networks) can cause interference. Try changing the wireless channel in the router's settings.
- Distance and Obstacles: The further you are from the router, or if there are many walls/obstacles, the weaker the signal will be. Try moving closer or repositioning the router.
- Firmware: Ensure your router has the latest firmware installed.
- Phone Line Interference: If using a DSL connection, ensure you have DSL filters installed on all phones connected to the same line as the modem.
Cannot Access Router's Web-Based Utility
- IP Address: Ensure your computer is configured to obtain an IP address automatically (DHCP).
- Default IP: Confirm you are using the correct default IP address (
http://192.168.0.1). - Firewall/Antivirus: Temporarily disable any software firewalls or antivirus programs on your computer that might be blocking access.
Resetting the Router to Factory Defaults
If you forget your password or encounter persistent issues, you can reset the router to its factory default settings.
- With the router powered on, locate the small reset button on the back panel (often recessed).
- Use a paperclip or a similar pointed object to press and hold the reset button for approximately 10 seconds.
- Release the button. The router will reboot, and all settings will be restored to their original factory defaults. You will then need to reconfigure the router.
