6. Troubleshooting
This chapter provides solutions to problems that can occur during the installation and
operation of the DCM-604. Read the following descriptions if you are having problems.
(The examples below are illustrated in Windows® XP. If you have a different operating
system, the screenshots on your computer will look similar to the following examples.)
1. Why can’t I access the web-based configuration 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 or have to be connected to the Internet. The device
has the utility built-in to a ROM chip 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 the
following:
• Internet Explorer 6.0 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
• Firefox 1.5 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 firewalls such
as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows® XP firewall
may block access to the configuration pages. Check the help files included with your
firewall software for more information on disabling or configuring it.

Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From
the Security tab, click the 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 web management. Open your web browser and enter the IP address of your
D-Link router in the address bar. This should open the login page for your the web
management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds
and plug back in. Wait about 30 seconds and try accessing the configuration. 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.
