Troubleshooting

Note: If you have changed

the default IP Address,

make sure to ping the cor-

rect IP Address assigned

to the DI-774.

1.The computer used to configure the DI-774 cannot access the

Configuration menu.

Check that the

Ethernet LED

on the DI-774 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-774.

Please see

Checking the IP Address

in Windows XP

in

the

Networking Basics

section of this manual.

Note:

The IP Address of the DI-774 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-774 is responding.

Go to

Start

>

Run

>Type

Command

>Type

ping 192.168.0.1.

A successful

ping will show four replies.

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

operation of the DI-774 Wireless Broadband 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-774 Wireless Broadband Router.

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.

Troubleshooting

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-774 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.

)
