Section 2 - Installation
Installation
This installation section is written for users who are setting up their home Internet service with the DSL-2740M Wireless N300 ADSL2+ Modem Router
for the rst time. If you are replacing an existing DSL modem and/or router, you may need to modify these steps.
Before you Begin
• Make sure to have your DSL service information provided by your Internet Service Provider (ISP) handy. This information is likely to
include your DSL account’s Username and Password. Your ISP may also supply you with additional WAN conguration settings which
are necessary to establish a connection. This information may include the connection type (DHCP IP, Static IP, PPPoE, or PPPoA) and/
or ATM PVC details.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time to label each cable
or take a picture of your existing setup before making any changes.
• We suggest setting up your DSL-2740M from a single device and verifying that it is connected to the Internet before connecting
additional devices.
• Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet, attic, or garage.
• 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 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 1 to 30 meters (3 to 90 feet). 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 0.5 meters (1.5 feet) thick, at a 45-degree angle appears to be
almost 1 meter (3 feet) thick. At a 2-degree angle it looks over 14 meters (42 feet) 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 dierence. A solid metal door or aluminum studs may have a negative eect 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 1 to 2 meters (3 to 6 feet) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz 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 2.4 GHz phone base is as far away from your
wireless devices as possible. The base transmits a signal even if the phone is not in use.

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).
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, XP, Vista®, and 7 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 DSL-2740M User Manual
Page 96
Section 5 - 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 congure 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 (192.168.1.1) and click OK.
• Enter your username (admin) and password (sometimes blank by default). Click OK to enter the web conguration page for the device.
• Click on Setup and then click Manual Congure.
• To change the MTU, enter the number in the MTU eld 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.

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 on 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 oce environments, and public areas such as airports, coee shops and universities. Innovative ways
to utilize WLAN technology are helping people work, and communicate more eciently. 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.
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.

Appendix A - Wireless Basics
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 oce 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 aord. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similarly to how cordless phones work, through radio signals that 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 dierent 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 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, university and
high school campuses, airports, golf courses, and many other outdoor venues.
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. This makes
94D-Link DSL-2740M User Manual
Page 99
Appendix A - Wireless Basics
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, oce, business, D-Link has a
wireless solution for it.
Home Uses/Benets
• Gives everyone at home broadband access
• Surf the web, check email, instant message, etc.
• Gets rid of the cables around the house
• Simple and easy to use
Small Oce and Home Oce Uses/Benets
• Stay on top of everything at home as you would at oce
• Remotely access your oce network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate oce space

Appendix A - Wireless Basics
Where is wireless used?
Wireless technology is expanding everywhere, not just at home or oce. 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 the Internet from remote locations like: airports, hotels,
coee 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
signicantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let your 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 detail information on how to set it up.
