Troubleshooting
1. How do I configure my DIR-120 router without the CD, or check my Wireless
Network Name (SSID) and Wireless Encryption Key?
• Connect your PC to the router using an Ethernet cable.
• Open a web browser and enter the address http://192.168.0.1
The default username is ‘admin’. The default password is ‘’ (leave the field blank).
• If you have changed the password and can not remember it, you will need to reset
the router to set the password back to ‘’ (leave the field blank).
2. How do I reset my router to factory default settings?
• Ensure the router is powered on.
• Press and hold the reset button on the rear of the device for 20 seconds.
Note: Resetting the router to factory default will erase the current configuration
settings. To re-configure your settings, log into the router as outlined in question
1, then run the Setup Wizard.
3. How do I add a new wireless client or PC if I have forgotten my Wireless Network
Name (SSID) or Wireless Encryption Key?
• For every PC that needs to connect to the router wirelessly, you will need to ensure
you use the correct Wireless Network Name (SSID) and encryption key.
• Use the web based user interface (as described in question 1 above) to check or
choose your wireless settings.
• Make sure you take a note of the settings so that you can enter them into each
wirelessly connected PC.
4. What can I do if my router is not working correctly?
• The manual contains a full troubleshooting section and can be downloaded from the
D-Link website (see below), however there are a few quick steps you can take to try
and resolve any issues:
• Check the LED’s on the front of the router. The Power, Wireless and Internet LED
should be on. One or more of the LAN LED should flash.
• Check that all the cables are firmly connected at both ends.
• Power the router off for 20 seconds, and then power it back on.
5. Why can I not get an Internet Connection?
• For Cable users make sure Clone MAC address option is ticked during Wizard
installation (or enter the registered MAC) and make sure the service has been
enabled/connected and is operational.
• For ADSL users please contact your ISP to make sure the service has been
enabled/connected by your ISP and that your ISP username and password is correct.
Note: If you are unable to connect, see the Troubleshooting chapter of the product
manual in the D-Link DIR-120 ETHERNET BROADBAND ROUTER CD.
