Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and

operation of the DI-724U Wireless G QoS Router. We cover various aspects of the

network setup, including the network adapters. Please read the following if you are

having problems.

Note:

It is recommended that you use an Ethernet connection to

configure the

DI-724U Wireless G QoS Router

.

1. The computer used to configure the DI-724U cannot access the Configuration

menu.



Check that the

Ethernet LED

on the DI-724U is

ON

. If the

LED

is not

ON

, check

that the cable for the Ethernet connection is securely inserted.



Check that the Ethernet Adapter is working properly.

Please see item 3

(

Check

that the drivers for the network adapters are installed properly

) in this

Troubleshooting

section to check that the drivers are loaded properly.



Check that the

IP Address

is in the same range and subnet as the DI-724U.

Please see

Checking the IP Address

in Windows XP

in the

Networking

Basics

section of this manual.

Note:

The IP Address of the DI-724U is 192.168.0.1. All the computers on the network

must have a unique IP Address in the same range, e.g., 192.168.0.x. Any computers

that have identical IP Addresses will not be visible on the network. They must all have

the same subnet mask, e.g., 255.255.255.0.



Do a

Ping test

to make sure that the DI-724U is responding. Go to

Start

>

Run

>Type

Command

>Type

ping 192.168.0.1.

A successful ping will show four replies.

Note: If you have changed the default IP Address, make sure to ping the correct IP

Address assigned to the DI-724U.

2. The wireless client cannot access the Internet in the Infrastructure mode.

Make sure the wireless client is associated and joined with the correct Access Point. To

check this connection:

Right-click

on the

Local Area Connection icon

in the taskbar

select

View Available Wireless Networks

. The

Connect to Wireless Network

screen

will appear.

Please make sure you have selected the correct available network, as

shown in the illustrations below.



Check that the

IP Address

assigned to the wireless adapter is within the same

IP Address range

as the access point and gateway.

(Since the

DI-724U has

an IP Address of 192.168.0.1, wireless adapters must have an IP Address in

the same range, e.g., 192.168.0.x.

Each device must have a unique IP Address;

no two devices may have the same IP Address. The subnet mask must be the

same for all the computers on the network.)

To check the

IP Address

assigned

to the wireless adapter,

double-click

on the

Local Area Connection icon

in the

taskbar

select the

Support tab

and the

IP Address

will be displayed.

(Please

refer to

Checking the IP Address

in the

Networking Basics

section of this

manual.)



If it is necessary to assign a

Static IP Address

to the wireless adapter, please

refer to the appropriate section in

Networking Basics

.

If you are entering a

DNS

Server address

you must also enter the

Default Gateway Address.

(Remember

that if you have a DHCP-capable router, you will not need to assign a Static IP

Address.

See

Networking Basics: Assigning a Static IP Address

.)
