Section 2 - Installation
Before you Begin
Installation
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 configure 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.
• When running the Setup Wizard from the D-Link CD, make sure the computer you are running the CD
from is connected to the Internet and online or the wizard will not work. If you have disconnected any
hardware, re-connect your computer back to the modem and make sure you are online.
D-Link DIR-635 User Manual
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. 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 (fish tanks), mirrors, file 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.
D-Link DIR-635 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.

Connect to Cable/DSL/Satellite Modem
D-Link DIR-635 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 Advanced and then click Advanced Network. Uncheck Enable UPnP and click Save Settings to continue.
4. Click Setup and then click Network Settings. Uncheck Enable DHCP Server and click Save Settings to
continue.
5. Under Router Settings, enter an IP address and the subnet mask of your network. Click Save Settings to save
your settings. Use this new IP address to access the configuration utility of the router in the future. Close the browser
and change your computer’s IP settings back to the original values as mentioned in step 1.
Connect to Another Router
D-Link DIR-635 User Manual
Section 2 - Installation
6. Disconnect the Ethernet cable from the router and reconnect your computer to your network.
7. Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug
anything into the Internet (WAN) port of the D-Link router.
8. You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To configure your wireless
network, open a web browser and enter the IP address you assigned to the router. Refer to the Configuration and
Wireless Security sections for more information on setting up your wireless network.

The DIR-635 can be configured 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-635 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked
with the DIR-635 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-635 redirects the external
service request to the appropriate server within the LAN network.
The DIR-635 is also capable of port-redirection meaning incoming traffic 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-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to
use that particular virtual service.

By default, the router automatically determines whether
the underlying connection is an xDSL/Frame-relay
network or some other connection type (such as cable
modem or Ethernet), and it displays the result as
Detected xDSL or Frame Relay Network. If you have an unusual network connection in which you are actually connected
via xDSL but for which you have configured as either Static or DHCP in the Internet settings, setting this option to xDSL or
Other Frame Relay Network ensures that the router will recognize that it needs to shape traffic slightly differently in order
to give the best performance. Choosing xDSL or Other Frame Relay Network causes the measured uplink speed to be
reported slightly lower than before on such connections, but gives much better results.

Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DIR-635 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-specific 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.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a
more secure public key encryption system to ensure that only authorized network users can access the network.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DIR-635. Read
the following descriptions if you are having problems. (The examples below are illustrated in Windows® XP. If you have
a different operating system, the screenshots on your computer will look similar to the following examples.)
1. Why can’t I access the web-based configuration 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 firewalls such as Zone Alarm, Black Ice,
Sygate, Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the
help files included with your firewall software for more information on disabling or configuring it.

• Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab,
click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click LAN Settings.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three
times.
• Close your web browser (if open) and then re-open it again.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address
bar. This should open the login page for your the web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait
about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different
computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back
to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a
paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process.
Wait about 30 seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is

3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, 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 find 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.
• Go to 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
D-Link DIR-635 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 find your MTU, you can now configure 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 configuration
page for the device.
• Click Setup and then click Manual Configure.
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
• Test your email. 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 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 cabling 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.
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
office 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.
D-Link DIR-635 User Manual
Appendix A - Wireless Basics
Wireless Personal Area Network (WPAN)
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, office,
business, D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, and etc
• Gets rid of the cables around the house
• Simple and easy to use
Small Office and Home Office
• Stay on top of everything at home as you would at office
• Remotely access your office network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate office space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. 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 Cardbus 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 first 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 significantly reduce any interference that the appliances might cause since they operate
on same frequency.

Appendix A - Wireless Basics
Security
Do not allow your 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 the Product Manual for further information.
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 wireless network Cardbus 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.

on your router. Some firewall software programs
may block a DHCP request on newly installed
adapters.

Statically Assign an IP address
If you are not using a DHCP capable gateway/router, and you want to assign a static IP address, please follow the
steps below:
Step 1
Windows® Vista - Go to Start > Control Panel > Network and Internet > Network and Sharing Center > Manage
Network Connections
Windows® XP -
Go to 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 sure your IP address
is 192.168.0.X, where X is a number between 2 and 99. Also, ensure that the
number you choose is not in use on the network. The Default Gateway should be
set similar to the LAN IP address of your router (192.168.0.1).
The Primary DNS should be 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.
