Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DAP-1555.

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 access point (192.168.0.50 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.

>

Control Panel

. Double-click the

Internet Options

Icon. From the

tab,

click the button to restore the settings to their defaults.

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 access point 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 access point 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 access point. Unfortunately this process will change all your settings

back to the factory defaults.

To reset the access point, locate the reset button (hole) on the rear panel of the unit. With the access point powered

on, use a paperclip to hold the button down for 10 seconds. Release the button and the access point will go through

its reboot process. Wait about 30 seconds to access the access point. The default IP address is 192.168.0.1. When

logging in, the username is

admin

and leave the password box empty.

3. Why can’t I connect to certain sites or send and receive emails when connecting through my access

point?

If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and

Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).

Note: AOL DSL+ users must use MTU of 1400.

To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could

be another computer, or a URL.

• Click on

Start

and then click

Run

.

• Windows

®

95, 98, and Me users type in

command

(Windows

®

NT, 2000, and XP users type in

cmd

) and

press

Enter

(or click

OK

).

• Once the window opens, you’ll need to do a special ping. Use the following syntax:

ping [url] [-f] [-l] [MTU value]

Example:

ping yahoo.com -f -l 1472
