technology. If you are using a DHCP-capable Gateway/Router you will not need to assign
Static IP Addresses.

Troubleshooting
This Chapter provides solutions to problems that can occur during the installation and
operation of the DI-524 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-524 Wireless Broadband Router.
1.The computer used to configure the DI-524 cannot access the
Configuration menu.
Check that the Ethernet LED on the DI-524 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-524. Please see Checking the IP Address in Windows XP in the
Networking Basics section of this manual.
Note: The IP Address of the DI-524 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-524 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-524.

Troubleshooting
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.
default
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-524 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.)

Troubleshooting
4. What variables may cause my wireless products
to lose reception?
D-Link products let you access your network from virtually anywhere you want. However,
the positioning of the products within your environment will affect the wireless range.
Please refer to Installation Considerations in the Wireless Basics section of this manual
for further information about the most advantageous placement of your D-Link wireless
products.
5. Why does my wireless connection keep dropping?
Antenna Orientation- Try different antenna orientations for the DI-524. Try to
keep the antenna at least 6 inches away from the wall or other objects.
If you are using 2.4GHz cordless phones, X-10 equipment or other home secu-
rity systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the Channel on your Router, Access
Point and Wireless adapter to a different Channel to avoid interference.
Keep your product away (at least 3-6 feet) from electrical devices that generate
RF noise, like microwaves, Monitors, electric motors, etc.
6. Why can’t I get a wireless connection?
If you have enabled Encryption on the DI-524, you must also enable encryption on all
wireless clients in order to establish a wireless connection.
For 802.11b, the Encryption settings are: 64 or 128 bit. Make sure that the en-
cryption bit level is the same on the Router and the Wireless Client.
Make sure that the SSID on the Router and the Wireless Client are exactly the
same. If they are not, wireless connection will not be established.
Move the DI-524 and the wireless client into the same room and then test the
wireless connection.
Disable all security settings. (WEP, MAC Address Control)

Troubleshooting
6. Why can’t I get a wireless connection? (continued)
Turn off your DI-524 and the client. Turn the DI-524 back on again, and then turn
on the client.
Make sure that all devices are set to Infrastructure mode.
Check that the LED indicators are indicating normal activity. If not, check that the
AC power and Ethernet cables are firmly connected.
Check that the IP Address, subnet mask, gateway, and DNS settings are cor-
rectly entered for the network.
If you are using 2.4GHz cordless phones, X-10 equipment or other home security
systems, ceiling fans, and lights, your wireless connection will degrade dramatically or drop altogether. Try changing the Channel on your DI-524, and on all the
devices in your network to avoid interference.
Keep your product away (at least 3-6 feet) from electrical devices that generate
RF noise, like microwaves, Monitors, electric motors, etc.
7. I forgot my encryption key.
Reset the DI-524 to its factory default settings and restore the other devices on
your network to their default settings. You may do this by pressing the Reset
button on the back of the unit. You will lose the current configuration settings.
