Section 2 - Installation
Before you Begin
This section will walk you through the installation process. Placement of the router is very important. Do not place the
router in an enclosed area such as a closet, cabinet, or in the attic or garage.
• Please congure the router with the computer that was last connected directly to your modem.
• You can only use the Ethernet port on your modem. If you were using the USB connection before using
the router, then you must turn off your modem, disconnect the USB cable and connect an Ethernet cable
to the Internet port on the router, and then turn the modem back on. In some cases, you may need to
call your ISP to change connection types (USB to Ethernet).
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software
such as WinPoet, Broadjump, or Enternet 300 from your computer or you will not be able to connect to
the Internet.

Section 2 - Installation
Wireless Installation Considerations
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within
the operating range of your wireless network. 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:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range 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 make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(sh tanks), mirrors, le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.
8D-Link DIR-603 User Manual
Section 2 - Installation
If you are connecting the router to a cable/DSL/satellite modem, please follow the steps below:
1. Place the router in an open and central location. Do not plug the power adapter into the router.
2. Turn the power off on your modem. If there is no on/off switch, then unplug the modem’s power adapter. Shut down
your computer.
3. Unplug the Ethernet cable (that connects your computer to your modem) from your computer and place it into the
Internet port on the router.
4. Plug an Ethernet cable into one of the four LAN ports on the router. Plug the other end into the Ethernet port on
your computer.
5. Turn on or plug in your modem. Wait for the modem to boot (about 30 seconds).
6. Plug the power adapter to the router and connect to an outlet or power strip. Wait about 30 seconds for the router
to boot.
7. Turn on your computer.
8. Verify the link lights on the router. The power light, Internet light, and the LAN light (the port that your computer is
plugged into) should be lit. If not, make sure your computer, modem, and router are powered on and verify the cable
connections are correct.
9. Skip to page 11 to congure your router.

9D-Link DIR-603 User Manual
Section 2 - Installation
If you are connecting the D-Link router to another router to use as a wireless access point and/or switch, you will have
to do the following before connecting the router to your network:
• Disable UPnP™
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot
accept a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable.
Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the
Networking Basics section for more information. If you need to change the settings, write down your existing settings
before making any changes. In most cases, your computer should be set to receive an IP address automatically in
which case you will not have to do anything to your computer.
2. Open a web browser and enter http://192.168.0.1 and press Enter. When the login window appears, set the user
name to Admin and leave the password box empty. Click Log In to continue.
3. Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings
to continue.
4. Click Setup and then click Network Settings. Uncheck the Enable DHCP Server server checkbox. Click Save
Settings to continue.
5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings to
save your settings. Use this new IP address to access the conguration utility of the router in the future. Close the
browser and change your computer’s IP settings back to the original values as in Step 1.

The DIR-603 can be congured as a virtual server so that remote users accessing Web or FTP services via the public
IP address can be automatically redirected to local servers in the LAN (Local Area Network).
The DIR-603 rewall feature lters out unrecognized packets to protect
your LAN network so all computers networked with the DIR-603 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 DIR-603 redirects the external
service request to the appropriate server within the LAN network.
The DIR-603 is also capable of port-redirection meaning incoming
trafc 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

SPI (Stateful Packet Inspection, also known as dynamic packet ltering)
helps to prevent cyber attacks by tracking more state per session. It
validates that the trafc passing through the session conforms to the
protocol.
If an application has trouble working from behind the router, you can
expose one computer to the Internet and run the application on that
computer.
Note: Placing a computer in the DMZ may expose that computer to
a variety of security risks. Use of this option is only recommended
as a last resort.

A rewall protects your network from the outside world. The D-Link DIR-603 offers a rewall type functionality. The SPI feature helps
prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications. If you choose
to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely
to the outside world.
IP Address: Specify the IP address of the computer on the LAN that you want to
have unrestricted Internet communication. If this computer obtains
its IP address automatically using DHCP, be sure to make a static
reservation on the Setup > Network Settings page so that the IP
address of the DMZ machine does not change.

Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The DIR-603
offers the following types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK(Pre-Shared Key)
• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t
been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead
of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specic MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.

have a different operating system, the screen shots on your computer will look similar to the following examples.)
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on
the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself.
Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 6.0 or higher
• Netscape 8 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using
a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may
not be on.
• Disable any Internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice,
Sygate, Norton Personal Firewall, and Windows® XP rewall may block access to the conguration pages. Check the

3. Why can’t I connect to certain sites or send and receive e-mails when connecting through my router?
If you are having a problem sending or receiving e-mail, or connecting to secure sites such as eBay, banking sites,
and Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
Note: AOL DSL+ users must use MTU of 1400.
To nd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination
could be another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
61D-Link DIR-603 User Manual
Section 6 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a
fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example,
lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network
we’re working with (1452+28=1480).
Once you nd your MTU, you can now congure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
• Enter your username (admin) and password (blank by default). Click OK to enter the web conguration
page for the device.
• Click on Setup and then click Manual Congure.
• To change the MTU enter the number in the MTU eld and click Save Settings to save your settings.
• Test your e-mail. If changing the MTU does not resolve the problem, continue changing the MTU in
increments of ten.

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. Strictly adhering to the IEEE standard,
the D-Link wireless family of products will allow you to securely access the data you want, when and where you want
it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and ofce 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 efciently. Increased mobility and the absence of cabling and other xed infrastructure have proven
to be benecial 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.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device
used to provide this link.

What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires.
Wi-Fi uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere
in your home or ofce network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking
products. D-Link delivers the performance you need at a price you can afford. D-Link has all the products
you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point
A to point B. But wireless technology has restrictions as to how you can access the network. You must be
within the wireless network range area to be able to connect your computer. There are two different types of
wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network.
The access point has a small antenna attached to it, which allows it to transmit data back and forth over radio
signals. With an indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor
access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial
locations, college and high school campuses, airports, golf courses, and many other outdoor venues.

Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate
in a range up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it
doesn’t use nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs,
headphones, laptops, speakers, and other devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for
home, ofce, business, D-Link has a wireless solution for it.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or ofce. People like the freedom of mobility
and it’s becoming so popular that more and more public facilities now provide wireless access to attract people.
The wireless connection in public places is usually called “hotspots”.
Using a D-Link USB Adapter with your laptop, you can access the hotspot to connect to Internet from remote
locations like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the rst time it could be quite a task not knowing
where to start. That’s why we’ve put together a few setup steps and tips to help you through the process of
setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best
performance. Try to place the router/access point as high as possible in the room, so the signal gets dispersed
throughout your home. If you have a two-story home, you may need a repeater to boost the signal to extend
the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible
from the router/access point. This would signicantly reduce any interference that the appliances might cause
since they operate on same frequency.

Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network
by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information
on how to set it up.
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless
network adapters on each computer, such as two or more DWM-140 wireless network USB adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect
to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in
Ad-Hoc mode to communicate.

Check your IP address
After you install your adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server
(i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK. (Windows Vista® users type in the Start Search box.)
At the prompt, type ipcong and press Enter.
This will display the IP address, subnet mask, and
the default gateway of your adapter.
If the address is 0.0.0.0, check your adapter
installation, security settings, and the settings on
your router. Some rewall software programs may
block a DHCP request on newly installed adapters.

Appendix B - Networking Basics
Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps
below:
Step 1
Windows Vista® - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage
Network Connections.
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same
subnet as your network or the LAN IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address
192.168.0.X where X is a number between 2 and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the LAN
IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
