Setup Wizard
The NETGEAR genie installation process is launched the first time you set up the router.
After setting up the router the first time, if you want to perform this task again, you can run
Setup Wizard from the Advanced tab of the NETGEAR genie.
1.
Select
Setup Wizard
to display the following screen:
2.

Yes
or
No, I want to configure the router myself
. If you select No, you are

WPS Wizard
The WPS Wizard helps you add a WPS-capable client device (a wireless device or computer)
to your network. On the client device, you need to either press its WPS button or locate its
WPS PIN.
To use the WPS Wizard:
1.
Select
Advanced > WPS Wizard
.
2.
Click
Next
. The following screen lets you select the method for adding the WPS client (a
wireless device or computer).
You can use either the push button or PIN method.
3.
Select either
Push Button
or
PIN Number
.
To use the push button method, either click the
WPS
button on this screen, or press
the
WPS
button on the side of the router. Within 2 minutes, go to the wireless client
and press its
WPS
button to join the network without entering a password.
To use the PIN method, select the
PIN Number
radio button, enter the client security
PIN, and click
Next
.

Within 2 minutes, go to the client device and use its WPS software to join the network
without entering a password.
The router attempts to add the WPS-capable device. The WPS LED
on the front of
the router blinks green. When the router establishes a WPS connection, the LED is solid
green, and the router WPS screen displays a confirmation message.
4.
Repeat Step 2 and Step 3 to add another WPS client to your network.

WAN Setup
The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the
maximum transmit unit (MTU) size, and enable the router to respond to a ping on the WAN
(Internet) port. Select
Advanced > Setup > WAN Setup
.
Disable Port Scan and DoS Protection
. DoS protection protects your LAN against
denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, Teardrop Attack,
UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This should be
disabled only in special circumstances.
Default DMZ Server
. This feature is sometimes helpful when you are playing online
games or videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See the following section,
Default DMZ Server
, for more
details.
Respond to Ping on Internet Port
. If you want the router to respond to a ping from the
Internet, select this check box. Use this only as a diagnostic tool because it allows your
router to be discovered. Do not select this check box unless you have a specific reason.
Disable IGMP Proxying
. IGMP proxying allows a computer on the local area network
(LAN) to receive the multicast traffic it is interested in from the Internet. You can select
this check box to disable the feature if you do not need it.
MTU Size (in bytes)
. The normal MTU (maximum transmit unit) value for most Ethernet
networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might
need to reduce the MTU. This is rarely required, and should not be done unless you are
sure that it is necessary for your ISP connection. See
Change the MTU Size
on page
35.
NAT Filtering
. Network Address Translation (NAT) determines how the router processes
inbound traffic. Secured NAT provides a secured firewall to protect the computers on the
LAN from attacks from the Internet, but might prevent some Internet games, point-to-point
applications, or multimedia applications from functioning. Open NAT provides a much
less secured firewall, but allows almost all Internet applications to function.

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 router is programmed to recognize some of these applications and to work
correctly with them, but other applications 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.
WARNING:
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.
The router discards incoming traffic from the Internet unless the traffic 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 the router forward traffic to
one computer on your network. This computer is called the default DMZ server.
To set up a default DMZ server:
1.
On the WAN Setup screen, select the
Default DMZ Server
check box.
2.
Type the IP address.
3.
Click
Apply
.
Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets
travel through many devices along the way. If any device in the data path has a lower MTU
setting than the other devices, the data packets have to be split or “fragmented” to
accommodate the device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often just the default value, and changing
the value might fix one problem but cause another. Leave MTU unchanged unless one of
these situations occurs:
You have problems connecting to your ISP or other Internet service, and the technical
support of either the ISP or NETGEAR recommends changing the MTU setting. These
web-based applications might require an MTU change:
-
A secure website that does not open, or displays only part of a web page
-
Yahoo email
-
MSN portal
-
America Online’s DSL service
