*Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary.
Network conditions and environmental factors, including volume of network traffic, building materials and
construction, and network overhead lower actual data throughput rate.
Introduction
The D-Link DI-624M Super G MIMO Wireless Router is an 802.11g high-perf ormance,
wireless router that supports high-speed wireless networking at home, at work or in
public places.
Unlike most routers, the DI-624M provides data transfers at up to 108 Mbps* (compared
to the standard 54 Mbps) when used with other D-Link Super G MIMO 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 sacrifice
some of 802.11g’s speed when y ou mix 802.11b and 802.11g de vices, b ut you will not
lose the ability to communicate when you incorporate the 802.11g standard into your
802.11b network. You may choose to slo wly 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-624M has the newest, strongest, most adv anced security features available toda y .
When used with other 802.11g WPA (WiFi Protected Access) compatible products in a
network, the security features include:
Introduction
WPA: Wi-Fi Protected Access authorizes and identifies 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.)

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 office
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 efficiently . Increased mobility and the absence of cab ling and other
fixed infrastructure have proven to be beneficial 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.
Wireless Basics
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 significantly improve worker efficiency.
Low Implementation Costs – WLANs are easy to set up , manage, change and relocate.
Networks that frequently change can benefit 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 f ast 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 office.
Scalability – WLANs can be configured in a v ariety of topologies to meet the needs of
specific applications and installations. Configurations 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.

Standards-Based Technology
The DI-624M Super G MIMO Wireless Router utiliz es the 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device, you
will be able to transfer large files 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 b y 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 (interf erence) in signal transmissions.
The DI-624M 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
Installation Considerations
The D-Link DI-624MSuper G MIMO Wireless Router 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 k ey to maximizing wireless range is to f ollow these basic
guidelines:
1 Keep the number of w alls and ceilings between the DI-624M and other network
devices to a minimum - each wall or ceiling can reduce your D-Link wireless
product’s r ange from 3-90 feet (1-30 meters.) Position your devices so that the
number of walls or ceilings is minimized.
2 Be aware of the direct line between network devices. A wall that is 1.5 feet 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.
3 Building Materials can impede the wireless signal - a solid metal door or aluminum
studs may hav e 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.
4 Keep y our product aw a y (at least 3-6 f eet or 1-2 meters) from electrical

a wireless client attempts to send wireless data. Enabling CTS
will add overhead and may lower wireless throughput.
None: CTS is typically used in a pure 802.11g environment. If
CTS is set to “None” in a mixed mode environment populated
by 802.11b clients, wireless collisions may occur frequently.
Always: CTS will always be used to make sure the wireless

What´s the difference between a crossover cable and a straight-through cable?
The wiring in crossover and straight-through cables are diff erent. The tw o types of cable
have different purposes for different LAN configurations. EIA/TIA 568A/568B define the
wiring standards and allow for two different wiring color codes as illustrated in the
following diagram.
Frequently Asked Questions
*The wires with colored backgrounds may have white stripes and may be denoted that
way in diagrams found elsewhere.
How to tell straight-through cable from a crossover cable:
The main way to tell the difference between the two cable types is to compare the
wiring order on the ends of the cable. If the wiring is the same on both sides, it is straightthrough cable. If one side has opposite wiring, it is a crossover cable.
All you need to remember to properly configure the cables is the pinout order of the two
cable ends and the following rules:
A straight-through cable has identical ends. A crossover cable has different ends.
It makes no functional difference which standard you follow for straight-through cable

standard as long as the other end is the other standard. It makes no functional difference
which end is which. The order in which you pin the cable is important. Using a pattern

6 What is DMZ?
Demilitarized Zone:
In computer networks, a DMZ (demilitarized zone) is a computer host or small network
inserted as a neutral zone between a company´s private network and the outside public
network. It prevents outside users from getting direct access to a server that has company
data. (The term comes from the geographic buffer z one that was set up between North
Korea and South K orea f ollowing the UN police action in the early 1950s.) A DMZ is an
optional and more secure approach to a firewall and effectively acts as a proxy server
as well.
In a typical DMZ configuration for a small company, a separate computer (or host in
network terms) receives requests from users within the private network for access to
Web sites or other companies accessible on the public network. The DMZ host then
initiates sessions for these requests on the public network. However, the DMZ host is
not able to initiate a session back into the private network. It can only forward packets
that have already been requested.
Frequently Asked Questions
Users of the public network outside the company can access only the DMZ host. The
DMZ may typically also have the company´s Web pages so these could be served to
the outside world. Ho wev er , the DMZ provides access to no other company data. In the
event that an outside user penetr ated the DMZ hosts security , the Web pages might be
corrupted but no other company information would be exposed. D-Link, a leading maker
of routers, is one company that sells products designed for setting up a DMZ
7 How do I configure the DMZ Host?
The DMZ feature allows y ou to forw ard all incoming ports to one computer on the local
network. The DMZ, or Demilitarized Zone, will allow the specified computer to be
exposed to the Internet. DMZ is useful when a cer tain application or game does not
work through the firewall. The computer that is configured for DMZ will be completely
vulnerable on the Internet, so it is suggested that you try opening ports from the Virtual
Server or Firewall settings before using DMZ.
Step 1: Find the IP address of the computer you want to use as the DMZ host.
T o find out ho w to locate the IP Address of the computer in Windo ws XP/2000/ME/9x or
Macintosh operating systems please refer to Step 4 of the first question in this section
(Frequently Ask ed Questions).

16 How do I use NetMeeting with my D-Link Router?
Unlike most TCP/IP applications, NetMeeting uses D YNAMIC PORTS instead of ST ATIC
PORTS. That means that each NetMeeting connection is somewhat different than the
last. F or instance, the HTTP web site application uses port 80. NetMeeting can use any
of over 60,000 diff erent ports.
All broadband routers using (only) standard NAT and all internet sharing programs like
Microsoft ICS that use (only) standard NAT will NOT work with NetMeeting or other
h.323 software packages.
Frequently Asked Questions
The solution is to put the router in DMZ.
Note: A few hardware manufacturers have taken it on themselves to actually provide
H.323 compatibility . This is not an easy task since the router m ust search each incoming
packet f or signs that it might be a netmeeting packet. This is a whole lot more work than
a router normally does and may actually be a weak point in the firewall. D-Link is not
one of the manufacturers.

17 How do I send or receive a file via iChat when the
Mac OSX firewall is active? -for Macintosh users- Mac
OS X 10.2 and later
The following information is from the online Macintosh AppleCare knowledge base:
“iChat cannot send or receive a file when the Mac OS X firewall is active in its default
state. If you have opened the AIM port, you may be able to receive a file but not send
them.
In its default state, the Mac OS X firewall blocks file transfers using iChat or America
Online AIM software. If either the sender or receiver has turned on the Mac OS X firewall,
the transfer may be blocked.
The simplest workaround is to temporarily turn off the firewall in the Sharing preference
pane on both computers. This is required for the sender. However, the receiver may
keep the firew all on if the AIM port is open. To open the AIM port:
Step 1: Choose Apple menu > System Preferences.
Frequently Asked Questions
Step 2: Choose Vie w > Sharing.
Step 3: Click the Firewall tab.
Step 4: Click New.
Step 5: Choose AOL IM from the Port Name pop-up menu. The number 5190 should
already be filled in for you.
Step 6: Click OK.
If you do not want to turn off the firewall at the sending computer , a diff erent file sharing
service may be used instead of iChat. The types of file sharing available in Mac OS X
are outlined in technical document 106461, "Mac OS X: File Sharing" in the AppleCare
Knowledge base online.
Note: If you use a file sharing service when the firewall is turned on, be sure to click the
Firewall tab and select the service you have chosen in the "Allow" list. If you do not do
this, the firewall will also block the file sharing service.

18 What is NAT?
NAT stands for Network Address Translator. It is proposed and described in RFC-
1631 and is used for solving the IP Address depletion problem. Basically, each NAT
box has a table consisting of pairs of local IP Addresses and globally unique addresses,
by which the box can “translate” the local IP Addresses to global address and vice
versa. Simply put, it is a method of connecting multiple computers to the Internet (or any
other IP network) using one IP Address.
D-Link´s broadband routers (ie: DI-624M) support NA T. With proper configuration, multiple
users can access the Internet using a single account via the NAT device.
For more information on RFC-1631: The IP Network Address Translator (NAT), visit
http://www .faqs.org/rfcs/rfc1631.html.

Securing Your Network
1. Change Admin Password
Changing the password to access your new router is the first step in securing your
network. This can done through the Wizard or on the Admin Page of the Tools tab.
There is no password by default and hackers will know this when trying to access your
network. Make sure that the password you choose is not commonly known or something
that is easy to guess such as your last name or your pet’ s name. T ry using a combination
of letters and numbers to deter intruders from hacking into your network. Your private
information should be kept private.
2. Disable DHCP and use Static IP addresses or Use Static DHCP and limit
scope to the amount of users on your network.
In the event that an intruder manages to gain access to your network, having DHCP
enabled makes it easier for the intruder to access other computers on your network.
There are two methods for getting around this. One is to disable DHCP and use static
IP addressing on all the devices connected to your netw ork. This would mean that the
intruder would have to know what IP network your devices are on in order to access
them. The second way is to change the scope of the DHCP server to only include
enough IP addresses for the de vices in your network. You can then use the Static DHCP
feature of the router to assign an IP address to each device on your network. Static
DHCP still dynamically assigns an IP address to your network devices but only allows
for those defined devices to obtain an IP address.
Appendix
3. Change the default LAN IP address
Change the default LAN IP address from 192.168.0.1 to an alternate IP address. There
are 3 ranges of IP addresses that have been reserved for use on Private Networks.
10.0.0.0 - 10.255.255.255 (10.0.0.0/8)
172.16.0.0 - 172.31.255.255 (172.16.0.0/12)
192.168.0.0 - 192.168.255.255 (192.168.0.0/16)
D-Link routers use 192.168.0.1 as their default LAN IP address. Choosing an alternate
IP address lessens the probabilty of an intruders knowing what IP network your devices
are on.
4. Set up MAC Filtering
Each networking device (router, network card, etc) on a network contains a unique
hexadecimal number that identifies that specific product. This number is ref erred to as
a MAC address. MAC filtering allows you to create a list of the MAC address of each
device on your network and only allows these specific devices to associate with your
network. With this feature enab led, de vices attempting to connect to y our network with
a MAC address that is not in the list you created, will be denied access.
