1.The computer used to configure the DWL-1750 cannot access

the Configuration menu.

Check that the

Ethernet Cable

is being used correctly. The

Crossover Ethernet cable that comes with the DWL-1750 is

used only when the unit is connected to your PC directly. If the

DWL-1750 is connected to a switch, a Straight-through cable

must be used, not a Crossover cable.

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 DWL-1750. Please see

Checking the IP Address

in

Windows XP

in the

Networking Basics

section of this

manual.

Note:

The default Ethernet

IP Address of the DWL-1750 is 192.168.0.50; the

default wireless IP Address is 192.168.1.50. 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 DWL-1750 is

responding. Go to

Start

>

Run

>Type

Command

>Type

ping

192.168.0.50.

A successful ping will show four replies.
