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
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
.)
