D-Link DSL-2740R
Section 2 - Installation
Wireless Installation Notes
DSL-2740R 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 (0.5 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 (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.

Section 2 - Installation
Device Installation
The DSL-2740R Wireless ADSL Router maintains three separate interfaces: an Ethernet LAN, a wireless LAN and an ADSL Internet (WAN) connection.
Carefully consider the router’s location’s suitability for connectivity for your Ethernet and wireless devices. You must have a functioning broadband
connection via a bridge device such as a Cable or ADSL modem in order to use the router’s WAN function.
Place the router in a location where it can be connected to various devices as well as to a power source. The router should not be located where it
will be exposed to moisture, direct sunlight or excessive heat. Make sure the cables and power cord are placed safely out of the way so they do not
create a tripping hazard. As with any electrical appliance, observe common sense safety procedures.
The router can be placed on a shelf, desktop, or other stable platform. If possible, you should be able to see the LED indicators on the front if you
need to view them for troubleshooting.
Power on Router
The router must be used with the power adapter included with the device.
1.
Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the router and plug the adapter into a suitable
nearby power source.
2.
Push down the Power button, and you should see the Power LED indicator light up and remain lit.
3.
If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make sure the connection is valid. The
router will attempt to establish the ADSL connection. If the ADSL line is connected and the router is properly configured this should light
up after several seconds. If this is the first time installing the device, some settings may need to be changed before the router can establish
a connection.

Section 2 - Installation
Factory Reset Button
The router may be reset to the original factory default settings by using a ballpoint or paperclip to gently push down the reset button in the
following sequence:
1.
Press and hold the reset button while the device is powered off.
2.
Turn on the power.
3.
Wait for 10~15 seconds and then release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings
will be restored to the factory default IP address
192.168.1.1
and the subnet mask 255.255.255.0. The default management Username is “admin”
and the default Password is
admin
.
Network Connections
Connect ADSL Line
Use the ADSL cable included with the router to connect it to a telephone wall socket or receptacle. Plug one end of the cable into the ADSL port (RJ-
11 receptacle) on the rear panel of the router and insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow the
instructions included with the device or given to you by your service provider. The ADSL connection represents the WAN interface, the connection
to the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection
to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the router to any
Ethernet device that is capable of operating at speeds higher than 10 Mbps, be sure that the device has auto-negotiation (NWay) enabled for the
connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the router is a crossed port (MDI X). Follow standard
Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the router directly to a PC or server, use
a normal straight-through cable. You should use a crossed cable when connecting the router to a normal (MDI-X) port on a switch or hub. Use a
normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The rules governing Ethernet cable lengths apply
to the LAN to router connection. Be sure that the cable connecting the LAN to the router does not exceed 100 meters.

Hub or Switch to Router Connection
Connect the router to an uplink port (MDI-II) on an Ethernet hub or switch
with a straight-through cable as shown in this diagram. If you wish to
reserve the uplink port on the switch or hub for another device, connect
to any of the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the router directly to a 10/100BASE-TX Ethernet adapter
card (NIC) installed on a PC using the Ethernet cable provided as shown
in this diagram.

Section 3 - Configuration
To access the configuration utility, open a web browser such as Internet
Explorer and enter the IP address of the router (192.168.1.1).
Type
admin
for the User Name and
admin
in the Password field.
Configuration
This section will show you how to configure your new D-Link wireless router using the web-based configuration utility.
Web-based Configuration Utility
Connect to the router
To configure the WAN connection used by the router it is first necessary to communicate with the router through its management interface, which
is HTML-based and can be accessed using a web browser. The easiest way to make sure your computer has the correct IP settings is to configure it
to use the DHCP server in the router. The next section describes how to change the IP configuration for a computer running a Windows operating
system to be a DHCP client.
