Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-878. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent

When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website, nor do you
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.
