Hardware Overview
Switching Between WAN Mode/3G Router Mode
The DIR-412 features a hardware switch that enables users to switch between WAN mode and 3G router mode.
When the DIR-412 is operating in WAN mode, WAN connectivity is achieved via the DIR-412’s Ethernet port. In this
mode LAN clients need to access the DIR-412 via the DIR-412’s wireless connection. When the DIR-412 is operating in
WAN mode network connectivity is more resilient as Internet connectivity can be failed over to a backup 3G connection,
if the main WAN connection fails.
When the DIR-412 is in 3G router mode, LAN clients can access the DIR-412 via the DIR-412’s Ethernet connection,
as well as via the wireless connection. The disadvantage of 3G router mode is that if the 3G connection fails, Internet
connectivity on the network will be lost.

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 Ethernet 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.

Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The DIR-412
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.
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-412. 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 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
help les included with your rewall software for more information on disabling or conguring it.

• Congure 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 the LAN Settings
button. 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 open it.
• 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 conguration, unplug the power to the router for 10 seconds and plug back in. Wait
about 30 seconds and try accessing the conguration. 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 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
91D-Link DIR-412 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>Internet and then click Manual Internet Connection Setup.
• 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 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 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 the product manual for detailed
information on how to set this 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 DIR-412 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.

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 cmd in the Start Search
box.)
At the prompt, type ipconfig 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.

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.
