Position Your Wireless Router
The wireless modem router lets you access your network from 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
p
referably 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 she
between the wireless modem router and your other devices to a minimum.
• Away from electrical devices that are potential source
fans, home security systems, microwaves, computers, or the base of a cordless phone or
2.4-GHz cordless phone.

s of interference, such as ceiling
• Away from any large metal surfaces, such as a solid me
tal 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 DGND4000 should be put in a vertical position only.

Plugs into ADSL line
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).
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

machines, and caller ID displays. Not every phone line in your home necessarily carries

.
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.
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.

Prepare to Set Up the Wireless Modem Router
You can set up your wireless modem router with the NETGEAR genie automatically, or you
can use the genie menus and screens to set up your wireless modem router manually.
However , before you start the setup process, you need to have you r ISP information ob hand
and make sure the laptops, computers, and other devices in the network have the settings
described here.
Use Standard TCP/IP Properties for DHCP
If you set up your computer to use a static IP address, you need to change the settings so
that it uses Dynamic Host Configuration Protocol (DHCP).
Gather ISP Information
If you have DSL broadband service, you might 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 this information, ask your ISP to provide it. When your
Internet connection is working, you no longer need to launch the ISP’ s login pro gram on your
computer to access the Internet. When you start an Internet application, your wireless

Enabling this option to turn off the SIP ALG might help your VoIP devices to create or

Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The wireless modem router is programmed to recognize some of these applications
and to work correctly with them, but there are other applications that might not function well.
In some cases, one local computer can run the application correctly if that computer’s IP
address is entered as the default DMZ server.
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall
and is exposed to exploits from the Internet. If compromised, the
DMZ server computer can be used to attack other computers on
your network.
Incoming traffic from the Internet is discarded by the wireless modem router unless the traf fic
is a response to one of your local computers or a service that you have configured in the Port
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have it
forwarded to one computer on your network. This computer is called the default DMZ server.

• You use VPN and have severe performance problems.

Note: An incorrect MTU setting can cause Internet communication
problems such as the inability to access certain websites, frames
within websites, secure login pages, or FTP or POP servers.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are
willing to experiment, you can gradually reduce the MTU from the maximum value of 1500
until the problem goes away. The following table describes common MTU sizes and
applications.

By default, the wireless modem router functions as a DHCP server, allowing it to assign IP,

wireless modem router. The wireless modem router assigns IP addresses to the attached
computers from a pool of addresses specified in this screen. Each pool address is tested
before it is assigned to avoid duplicate addresses on the LAN. For most applications, the
default DHCP and TCP/IP settings of the wireless modem router are satisfactory.

server. Reserved IP addresses should be assigned to computers or servers that require
permanent IP settings.
To reserve an IP address:
1. In the Address Reservation section of the screen, click the Add
button. The following
screen displays:
2. In the IP Address field, type the IP addres s to assign to t he comput er o r server. (Choose an

Quality of Service Setup
Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of
traffic ahead of others. The N750 Modem Router can provide QoS prioritization over the
wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen.
Select ADVANC
ED > Setup > QoS Setup to display the following screen:
Enable WMM QoS for Wireless Multimedia Applications
The N750 Modem Router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to
prioritize wireless voice and video traffic over the wireless link. WMM QoS provides
prioritization of wireless data packets from different applications based on four access
categories: voice, video, best effort, and background. For an application to receive the
benefits of WMM QoS, both it and the client running that application have to have WMM
enabled. Legacy applications that do not support WMM and applications that do not require
QoS are assigned to the best effort category, which receives a lower priority than voice and
video.
WMM QoS is enabled by default. You can disable it in the QoS Setup screen by clearing the

Firewall Rules
Services are functions performed by server computers at the request of client computers. For
example, web servers serve web pages, time servers serve time and date information, and
game hosts serve data about other players’ moves. When a computer on the Internet sends
a request for service to a server computer, the requested service is identified by a service or
port number. This number appears as the destination port number in the transmitted IP
packets. For example, a packet that is sent with the destination port number 80 is an HTTP
(web server) request.
The service numbers for many common protocols are defin
