If this check box is selected, the router communicates wirelessly only with other APs whose MAC
addresses are listed in this screen. The router still communicates with wire-connected LAN
devices.
Setting Up the Base Station
The wireless repeating function works only in hub and spoke mode. The units cannot be daisy
chained. You must know the wireless settings for both units. You must know the MAC address of
the remote unit. First, set up the base station, and then set up the repeater. To set up the base
station:
1.
Set up both units with exactly the same wireless settings (SSID, mode, channel, and security).
Note that the wireless security option must be set to
None
or
WEP
.
Note:
The WNDR3700 router is always in dual band concurrent mode, unless you turn
off one radio. Be aware that if you enable the wireless repeater in either radio band,
the wireless base station or wireless repeater cannot be enabled in the other radio
band. However, if you enable the wireless base station in either radio band and use
the other radio band as a wireless router or wireless base station, dual band
concurrent mode is not affected.

2.
Log into the wireless router base unit, under the Advanced heading, select
Wireless
Repeating Function
to display the Wireless Repeating Function screen.
3.
In the Wireless Repeating Function screen (depending on the frequency you want to use),
select the
Enable Wireless Repeating Function
check box and the
Wireless Base Station
radio button.
4.
Enter the MAC address for one or more repeater units.

Setting Up a Repeater Unit
Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the wireless
connection to the base station.
To configure a WNDR3700 router as a repeater unit:
1.
Log in to the router that will be the repeater. Check the Wireless Settings screen, and verify
that the wireless settings match the base unit exactly. The wireless security option must be set
to
WEP
or
None
.
2.
In the Wireless Repeating Function screen (depending on the frequency you want to use),
select the
Enable Wireless Repeating Function
check box and the
Wireless Repeater
radio
button.
3.
Fill in the
Repeater IP Address
field. This IP address must be in the same subnet as the base
station, but different from the LAN IP of the base station
4.
Click
Apply
to save your changes.
5.
Verify connectivity across the LANs.
A computer on any wireless or wired LAN segment of the wireless router should be able to
connect to the Internet or share files and printers with any other wireless or wired computer or
server connected to the other AP.
Note:
If you are using the WNDR3700 base station with a non-NETGEAR wireless
router as the repeater, you might need to change additional configuration settings.
In particular, you should disable the DHCP server function on the wireless
repeater AP.

Chapter 6
Fine-Tuning Your Network
This chapter describes features to help you manage your RangeMax Dual Band Wireless-N
Gigabit Router WNDR3700.
This chapter includes the following sections:
“Assessing Your Speed Requirements” on page 6-2
“Optimizing Your Network Bandwidth” on page 6-3
“Optimizing Wireless Performance” on page 6-5
“Changing the MTU Size” on page 6-6
“Quality of Service (QoS)” on page 6-7
Common connection types and their speed and security considerations are:
Broadband Internet
. Your Internet connection speed is determined by your modem type,
such as ADSL or cable modem, as well as the connection speed of the sites to which you
connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical,
meaning they have a lower data rate
to
the Internet (upstream) than
from
the Internet
(downstream). Keep in mind that when you connect to another site that also has an
asymmetrical connection, the data rate between your sites is limited by each side’s upstream
data rate. A typical residential ADSL or cable modem connection provides a downstream
throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+
and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.
Wireless
. Your RangeMax Dual Band Wireless-N Gigabit Router WNDR3700 provides a
wireless data throughput of up to 300 Mbps using technology called multiple input, multiple
output (MIMO), in which multiple antennas transmit multiple streams of data. The use of
multiple antennas also provides excellent range and coverage. With the introduction of the
newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely
strong.
To get the best performance, use RangeMax adapters, such as the WNDA3100, for your
computers. Although the RangeMax router is compatible with older 802.11b and 802.11g
adapters, the use of these older wireless technologies in your network can result in lower
throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for
802.11g). In addition, many older wireless products do not support the latest security
protocols, WPA and WPA2.

Powerline
. For connecting rooms or floors that are blocked by obstructions or are distant
vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD
family of products delivers up to 200 Mbps to any outlet, while the older-generation XE
family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for
security, and you can configure an individual network password to prevent neighbors from
connecting.
The Powerline HD family of products can coexist on the same network with older-generation
XE family products or HomePlug 1.0 products, but they are not interoperable with these older
products.
Wired Ethernet
. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on
newer computers, wired Ethernet remains a good choice for speed, economy, and security.
Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A
wired connection is not susceptible to interference, and eavesdropping would require a
physical connection to your network.
Assessing Your Speed Requirements
Because your Internet connection is likely to operate at a much lower speed than your local
network, faster local networking technologies might not improve your Internet experience.
However, many emerging home applications require high data rates. For example:
Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can
disrupt your video, plan to provide at least twice the capacity you need.
Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern
networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so
a congested network or a noisy link can cause problems.
Note:
Actual data throughput will vary. Network conditions and environmental factors,
including volume of network traffic, building materials and construction, and
network overhead, can lower actual data throughput rate.
