Introduction
The D-Link DI-524 is based on 802.11n technology, wireless router that supports high-
speed wireless networking at home, at work or in public places.
Unlike most routers, the DI-524 provides data transfers at up to 150 Mbps (compared to
the standard 54 Mbps) when used with other D-Link N products. The 802.11g standard
is backwards compatible with 802.11b products. This means that you do not need to
change your entire network to maintain connectivity. You may sacrice some of 802.11g’s
speed when you mix 802.11b and 802.11g devices, but you will not lose the ability to
communicate when you incorporate the 802.11g standard into your 802.11b network.
You may choose to slowly change your network by gradually replacing the 802.11b
devices with 802.11g devices .
In addition to offering faster data transfer speeds when used with other 802.11g products,
the DI-524 has the newest, strongest, most advanced security features available today.
When used with other 802.11g WPA (WiFi Protected Access) and 802.1x compatible
products in a network with a RADIUS server, the security features include:
WPA: Wi-Fi Protected Access authorizes and identies users based on a secret key
that changes automatically at a regular interval. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a
packet is a kind of message transmitted over a network.) This insures much
greater security than the standard WEP security. (By contrast, the older WEP
encryption required the keys to be changed manually.)
802.1x: Authentication is a rst line of defense against intrusion. In the Authentication
process the server veries the identity of the client attempting to connect to the
network. Unfamiliar clients would be denied access.
For home users that will not incorporate a RADIUS server in their network, the security
for the DI-524, used in conjunction with other 802.11g products, will still be much stronger
than ever before. Utilizing the Pre Shared Key mode of WPA, the DI-524 will obtain a
new security key every time it connects to the 802.11g network. You only need to input
your encryption information once in the conguration menu. No longer will you have to
manually input a new WEP key frequently to ensure security, with the DI-524, you will
automatically receive a new key every time you connect, vastly increasing the safety
of your communications.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and
compatible high-speed wireless connectivity within your home, business or public
access wireless networks. D-Link wireless products will allow you access to the data
you want, when and where you want it. You will be able to enjoy the freedom that
wireless networking brings.
A WLAN is a cellular computer network that transmits and receives data with radio signals
instead of wires. WLANs are used increasingly in both home and ofce environments,
and public areas such as airports, coffee shops and universities. Innovative ways to
utilize WLAN technology are helping people to work and communicate more efciently.
Increased mobility and the absence of cabling and other xed infrastructure have proven
to be benecial for many users.
Wireless users can use the same applications they use on a wired network. Wireless
adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards.
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any location
within the operating range of the WLAN. Management decisions based on real-time
information can signicantly improve worker efciency.
Low Implementation Costs – WLANs are easy to set up, manage, change
and relocate. Networks that frequently change can benet from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring may be
impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and
easy and can eliminate the need to pull cable through walls and ceilings. Wireless
technology allows the network to go where wires cannot go - even outside the home
or ofce.
Scalability – WLANs can be congured in a variety of topologies to meet the needs
of specic applications and installations. Congurations are easily changed and range
from peer-to-peer networks suitable for a small number of users to larger infrastructure
networks to accommodate hundreds or thousands of users, depending on the number
of wireless devices deployed.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.

Wireless Basics (continued)
Standards-Based Technology
The DI-524 Wireless Broadband Router utilizes the new 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specied range of this device, you
will be able to transfer large les quickly or even watch a movie in MPEG format over
your network without noticeable delays. This technology works by transmitting highspeed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division
Multiplexing) technology. OFDM works by splitting the radio signal into multiple
smaller sub-signals that are then transmitted simultaneously at different frequencies
to the receiver. OFDM reduces the amount of crosstalk (interference) in signal
transmissions.
The DI-524 is backwards compatible with 802.11b devices. This means that if you have
an existing 802.11b network, the devices in that network will be compatible with 802.11g
devices at speeds of up to 11Mbps in the 2.4GHz range.

Wireless Basics (continued)
Installation Considerations
The DI-524 lets you access your network, using a wireless connection, from virtually
anywhere within its operating range. Keep in mind, however, that the number, thickness
and location of walls, ceilings, or other objects that the wireless signals must pass
through, may limit the range. Typical ranges vary depending on the types of materials
and background RF (radio frequency) noise in your home or business. The key to
maximizing wireless range is to follow these basic guidelines:
Keep the number of walls and ceilings between the DI-524 and other network
1
devices to a minimum - each wall or ceiling can reduce your D-Link wireless
product’s range from 3-90 feet (1-30 meters.) Position your devices so that
the number of walls or ceilings is minimized.
Be aware of the direct line between network devices. A wall that is 1.5 feet
2
thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter)
thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position
devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
Building Materials can impede the wireless signal - a solid metal door or
3
aluminum studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
4
devices or appliances that generate extreme RF noise.

in the LAN (Local Area Network).
The DI-524 rewall feature lters out unrecognized packets to protect your LAN network
so all computers networked with the DI-524 are invisible to the outside world. If you wish,
you can make some of the LAN computers accessible from the Internet by enabling Virtual
Server. Depending on the requested service, the DI-524 redirects the external service
request to the appropriate server within the LAN network.
The DI-524 is also capable of port-redirection meaning incoming trafc to a particular
port may be redirected to a different port on the server computer.
Each virtual service that is created will be listed at the bottom of the screen in the
Virtual Servers List. There are pre-dened virtual services already in the table. You
may use them by enabling them and assigning the server IP to use that particular

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
congure the DI-524 Wireless Broadband Router.
1. The computer used to congure the DI-524 cannot access the
Conguration 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.
55
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.
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
security 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, 128, or 256 bit. Make sure that
the encryption 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)
59
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 rmly 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 se-
curity 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 conguration settings.
