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
