Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DWR-512.

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 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.

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.

To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the

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 leave the password box empty.

Appendix A - Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within

your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link wireless family of products

will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless

networking delivers.

A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires.

Wireless LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities.

Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the

absence of cabling and other fixed infrastructure have proven to be beneficial for many users.

Wireless users can use the same applications they use on a wired network.

Wireless adapter cards used on laptop and desktop systems

support the same protocols as Ethernet adapter cards.

Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers,

printers or an Internet connection supplied through the wired LAN.

A Wireless Router is a device used to provide this link.
