Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-2888A. Read the following descriptions
if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent operating system, the screenshots on your
computer will look similar to these examples.
Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.1.1 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.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
- Microsoft Internet Explorer® 10 or higher
- Mozilla Firefox 28 or higher
- Google™ Chrome 28 or higher
- Apple Safari 6 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 dierent cable, or connect
to a dierent port on the device if possible. If the computer is turned o, the link light may not be on.
• Disable any Internet security software running on the computer. Software rewalls such as ZoneAlarm, BlackICE, Sygate, Norton Personal Firewall,
and Windows
®
XP rewall may block access to the conguration pages. Check the help les included with your rewall software for more information
on disabling or conguring it.
