Position Your Wireless Router
The wireless modem router lets you access your network from virtually anywhere within the
operating range of your wireless network. However, the operating distance or range of your
wireless connection can vary significantly depending on the physical placement of your
router. For example, the thickness and number of walls the wireless signal passes through
can limit the range. For best results, place your router:
• Near the center of the area where your computers and other devices operate, and
preferably within line of sight to your wireless devices.
• So it is accessible to an AC power outlet and near Ethernet cables for wired computers.
• In an elevated location such as a high shelf, keeping the number of walls and ceilings
between the wireless modem router and your other devices to a minimum.
• Away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, PCs, or the base of a cordless phone or 2.4
GHz cordless phone.
• Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large
expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and
concrete can also affect your wireless signal.
Note: The DGND3700 should be put in a vertical position only.
Also be aware that when you use multiple access points, it is better if adjacent access points
use different radio frequency channels to reduce interference. The recommended channel
spacing between adjacent access points is five channels (for example, use Channels 1 and
6, or 6 and 11).
Hardware Setup
17
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700
ADSL Microfilters
If this is the first time you have cabled a wireless router between an ADSL phone line and
your computer or laptop, you might not be familiar with ADSL microfilters. If you are, you can
skip this section and proceed to Cable Your N600 Wireless Modem Router on page 20.
An ADSL microfilter is a small in-line device that filters ADSL interference out of standard
phone equipment that shares the same line with your ADSL service. Every telephone device
that connects to a telephone line that provides ADSL service needs an ADSL microfilter to
filter out the ADSL interference. Example devices are telephones, fax machines, answering
machines, and caller ID displays. Note that not every phone line in your home necessarily
carries ADSL service. That depends on the ADSL service setup in your home.
Note: Often the ADSL microfilter is included in the box with the wireless
modem router. If you purchased the wireless modem router in a
country where a microfilter is not included, you have to acquire the
ADSL microfilter separately.
One-Line ADSL Microfilter (Not Included)
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack
labeled Phone. The wireless modem router plugs directly into a separate ADSL line. Plugging
the wireless modem router into the phone jack blocks the Internet connection. If you do not
have a separate ADSL line for the router, the best thing to do is to use an ADSL microfilter
with a built-in splitter.
Plugs into ADSL line
Figure 5. One-line ADSL microfilter
Second best when you do not have a separate ADSL line for the router is to get a separate
splitter. To use a one-line filter with a separate splitter, insert the splitter into the phone outlet,
connect the one-line filter to the splitter, and connect the phone to the filter.
Hardware Setup
18
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700
Two-Line ADSL Microfilter (Included)
Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides
connectivity for both the wireless modem router and your telephone equipment. Plug the
ADSL microfilter into the wall outlet, plug your phone equipment into the jack labeled Phone,
and plug the wireless modem router into the jack labeled ADSL.
Plugs into the ADSL line
Figure 6. Two-line ADSL microfilter with built-in splitter
Summary
• One-line ADSL microfilter (not included). Use with a phone or fax machine.
• Splitter (not included). Use with a one-line ADSL microfilter to share an outlet with a
phone and the wireless modem router.
• Two-line ADSL microfilter with built-in splitter (included). Use to share an outlet with a
phone and the wireless modem router.

Router Setup Preparation
You can set up your wireless modem router with the Setup Wizard as described in Setup
Wizard on page 27 or manually as described in Manual Setup (Basic Settings) on page 28.
However, before you start the setup process, you need to have your ISP information on hand
and make sure the laptops, PCs, and other devices in the network have the settings
described here.
Note: If you have a Macintosh or Linux system, you have to use the
manual setup method.
Use Standard TCP/IP Properties for DHCP
If you configured your computer to use a static IP address, you need to change the settings
back so that it uses Dynamic Host Configuration Protocol (DHCP). See
Supplemental Information for more information.
Appendix A,
Replace an Existing Router
To replace an existing router, disconnect it completely from your network and set it aside
before starting the router setup.
Adapters and Security Settings
A wireless adapter is the wireless radio in your PC or laptop that lets the PC or laptop
connect to a wireless network. Most PCs and laptops come with an adapter already installed,
but if it is outdated or slow, you can purchase a USB adapter to plug into a USB port.
Make sure the wireless adapter in each computer in your wireless network supports the same
security settings as the wireless modem router. See
Recommendations on page 37 for information about the router’s security settings.
Note: If you connect devices to your modem router using WPS as
described in
those devices assume the security settings of the router.
Wi-Fi Protected Setup (WPS) Method on page 40,
Wireless Security Requirements and
Gather ISP Information
You need the following information to set up your wireless modem router and to check that
your Internet configuration is correct. Your Internet service provider (ISP) should have
provided you with all of the information needed to connect to the Internet. If you cannot locate
Router Internet Setup
23
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700
this information, ask your ISP to provide it. When your Internet connection is working, you no
longer need to launch the ISP’s login program on your computer to access the Internet. When
you start an Internet application, your wireless modem router automatically logs you in.
• Active Internet service provided by an ADSL account
• The ISP configuration information for your ADSL account
- ISP login name and password
- ISP Domain Name Server (DNS) addresses
- Fixed or static IP address
- Host and domain names
- Depending on how your ISP set up your Internet account, you could need to know
one or more of these settings for a manual setup:
- Virtual path identifier (VPI) and virtual channel identifier (VCI) parameters
- Multiplexing method
- Host and domain names
