Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-400. Read
the following descriptions if you are having problems.
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on
the Internet nor do you have to be connected to the Internet. The device has the utility built into a ROM chip located
in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend using one of the following:
• Internet Explorer 6.0 or higher
• Firefox 1.5 or higher
• Netscape 8 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using
a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may
not be on.
• Disable any internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice,
Sygate, Norton Personal Firewall, and Windows® XP’s rewall may block access to the conguration pages. Check
the help les included with your rewall software for more information on disabling or conguring it.

• Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab,
click the Default Level button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings
button. Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three
times.
• Close your web browser (if open) and open it.
• Access the router’s web management.
• Open your web browser and enter the IP address of your D-Link router in the address bar. This should openOpen your web browser and enter the IP address of your D-Link router in the address bar. This should open
the login page for web management.
• If you still cannot access the router’s conguration pages, unplug the power to the router for 10 seconds and
plug back in. Wait about 30 seconds and try accessing the conguration. If you have multiple computers, try
connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back
to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use an
unfolded paperclip to hold the reset button down for 10 seconds. Release the button and the router will go through its
reboot process. Wait about 30 seconds to access the router. The default IP address is 192.168.0.1. When logging in,
the username is admin and you should leave the password box empty.
