Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-2740B.
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 (192.168.1.1 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
• Firefox 3.0 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
Start
>
Settings
>
Control Panel
. Double-click the
Internet Options
Icon. From the
Security
tab, click the button to restore
the settings to their defaults.
• Click the
Connection
tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing
is checked. Click
OK
.
• Go to the
Advanced
tab and click the button to restore these settings to their defaults. Click
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 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. For information
about logging into the router see page 12.

Networking Basics
Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless
router) 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 adapter installation, security
settings, and the settings on your router. Some firewall software
programs may block a DHCP request on newly installed
adapters.
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.
