Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-±3±0B.
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 th3e following examples.)
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link modem (19±.168.1.1 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 1.7.1± (5.0) or higher
• Opera 8.5 or higher
• Safari 1.± 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.

• Configure your Internet settings:
• Go to

OK
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 modem 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 modem 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 modem. Unfortunately this process will change all your settings back
to the factory defaults.
To reset the modem, locate the reset button (hole) on the rear panel of the unit. With the modem powered on, use a
paperclip to hold the button down for 10 seconds. Release the button and the modem will go through its reboot process.
Wait about 30 seconds to access the modem. For information about logging into the modem see page 16.

Check your IP address
After you install your new D-Link device, by default, the TCP/IP settings should be set to obtain an IP address from a
DHCP server (i.e. wireless modem) automatically. To verify your IP address, please follow the steps below.
Click on
Start
>
Run
. In the run box type
cmd
and click
OK
.
At the prompt, type
ipconfig
and press
Enter
.
This will display the IP address, subnet mask, and
the default gateway of your adapter.
If the address is 0.0.0.0, check your device
installation, security settings, and the settings on
your modem. Some firewall software programs may
block a DHCP request on newly installed device.
If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee
or administrator to verify their wireless network settings.
Check your MAC address
Click on
Start
>
Run
. In the run box type
cmd
and click
OK
.
At the prompt, type
ipconfig /all
and press
Enter
.
This will display information about all installed adapters on your computer. Your MAC address is listed as the
“Physical Address” and should look like xx-xx-xx-xx-xx-xx or xx:xx:xx:xx:xx:xx

Statically Assign an IP address
If you are not using a DHCP capable gateway/modem, or you need to assign a static IP address, please follow the
steps below:
Step 1
Windows
®
XP - Click on
Start
>
Control Panel
>
Network Connections
.
Windows
®
±000 - From the desktop, right-click
My Network Places
>
Properties
.
Step 2
Right-click on the
Local Area Connection
which represents your D-Link network adapter and select
Properties
.
Step 3
Highlight
Internet Protocol (TCP/IP)
and click
Properties
.
Step 4
Click
Use the following IP address
and enter an IP address that is on the same subnet as your network or the LAN
IP address on your modem.
Example: If the modem´s LAN IP address is 19±.168.0.1, make your IP address
19±.168.0.X where X is a number between ± and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the LAN
IP address of your modem (19±.168.0.1).
Set Primary DNS the same as the LAN IP address of your modem (19±.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
