 Input your IP address and
subnet mask. (The IP
Addresses on your network
must be within the same
range. For example, if one
computer has an IP Address
of 192.168.0.2, the other
computers should have IP
Addresses that are
sequential, like 192.168.0.3
and 192.168.0.4. The subnet
mask must be the same for
all the computers on the
network.)

Troubleshooting
This Chapter provides solutions to problems that can occur during the installation and
operation of the DI-624 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: If you have
changed the default IP
Address, make sure to
ping the correct IP
Address assigned to the
DI-624.
Note:  It is recommended that you use an Ethernet connection to
configure the DI-624 Wireless Broadband Router.
1.The computer used to configure the DI-624 cannot access the
   Configuration menu.
Check that the Ethernet LED on the DI-624 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-624.  Please see Checking the IP Address in Windows XP in
the Networking Basics section of this manual.
Note:  The IP Address of the DI-624 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-624 is responding.  Go to
Start>Run>Type Command>Type ping 192.168.0.1.  A successful
ping will show four replies.
						

							56 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-624 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.)

3.  Check that the drivers for the network adapters are
      installed properly.
You may be using different network adapters than those illustrated here, but this
procedure will remain the same, regardless of the type of network adapters you are
using.

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?
6.  Why can’t I get a wireless connection?
If you have enabled Encryption on the DI-624, you must also enable encryption on all
wireless clients in order to establish a wireless connection.
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. For 802.11b, the Encryption settings are: 64, 128, or 256 bit.  Make sure that the
encryption bit level is the same on the Router and the Wireless Client.

6.  Why can’t I get a wireless connection? (continued)
Turn off your DI-624 and the client. Turn the DI-624 back on again, and then turn
on the client.
