It may take 20-30 seconds to connect to the wireless network. If the connection fails,

please verify that the WPA-PSK settings are correct. The WPA-PSK passphrase must be

exactly the same as on the wireless router.

Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DWR-730.

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.

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. How can I upgrade the firmware on the device?

To update the firmware on the DWR-730, connect the device into an available USB port on your PC. Next, log into the WebGUI and navigate to the

Tools

tab near the top. Then click on the

Firmware Upgrade

tab on the left. Browse for the firmware image file and click

Upgrade

. Please do not

disconnect the DWR-730 while the upgrade is in progress.

Note

3. I’m having problems installing the D-Link Connection Manager.

Your antivirus program may be preventing installation of the software. Try disabling your antivirus software temporarily while you install the D-Link

Connection Manager.

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.

What is Wireless?

Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect

wirelessly, so you have the freedom to connect computers anywhere in your home or office network.

Why D-Link Wireless

?

D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products.

D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your network.

How does wireless work?

Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has

restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There

are two different types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).

Wireless Local Area Network (WLAN)

In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna

attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point as seen in the picture, the signal can

travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial

locations, college and high school campuses, airports, golf courses, and many other outdoor venues.

Wireless Personal Area Network (WPAN)

Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away.

Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as much power which

makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.
