Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DIR-455. 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.
