ou use VPN and have severe performance problems.
•Y
ou used a program to optimize MTU for performance reasons, and now you h\
ave 
connectivity or 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. 
Table 3.  Common MTU sizes   
MTUApplication
1500 The largest Ethernet packet size and the default value. This is the typical setting for 
non-PPPoE, non-VPN connections, and is the default value for NETGEAR rou\
ters, 
adapters, and switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)

LAN Setup
The LAN Setup screen allows configuration of LAN IP services such as Dyn\
amic Host 
Configuration Protocol (DHCP) and Routing Information Protocol (RIP)\
.
The router is shipped preconfigured to use private IP addresses on the L\
AN side and to act  as a DHCP server
 . The router’s default LAN IP configuration is:
• LAN IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
These addresses are part of the designated private address range for use\
 in private networks  and should be suitable for most applications. If your network requires a\
 dif
 ferent IP 
addressing scheme, you can make the changes in the LAN Setup screen.
To change the LAN settings:
Note: If you change the LAN IP address of the router while connected 
through the browser, you will be disconnected. Open a new 
connection to the new IP address and log in again.
1.  Select  Advanced > Setup > LAN Setup to display the following screen:
2. Enter the settings that you want to customize. These settings are described in the following 
section,  LAN Setup Screen Settings.
3.  Click  Apply  to save your changes.

LAN Setup Screen Settings
LAN TCP/IP Setup
•IP Address. The LAN IP address of the router.
•IP Subnet Mask. The LAN subnet mask of the router. Combined with the IP address, the 
IP subnet mask allows a device to know which other addresses are local to it, and which 
have to be reached through a gateway or router.
•RIP Direction. Router Information Protocol (RIP) allows a router to exchange routing 
information with other routers. This setting controls how the router sends and receives 
RIP packets. Both is the default setting. With the Both or Out Only setting, the router 
broadcasts its routing table periodically. With the Both or In Only setting, the router 
incorporates the RIP information that it receives.
•RIP Version. Controls the format and the broadcasting method of the RIP packets that 
the router sends. It recognizes both formats when receiving. By default, the RIP function 
is disabled. 
RIP-1 is universally supported. It is adequate for most networks, unless you have an 
unusual network setup. 
RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 
format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.
Use Router as a DHCP Server 
This check box is selected so that the router functions as a Dynamic Host Configuration 
Protocol (DHCP) server. 
•Starting IP Address. Specify the start of the range for the pool of IP addresses in the 
same subnet as the router.
•Ending IP Address. Specify the end of the range for the pool of IP addresses in the 
same subnet as the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer receives 
the same IP address each time it accesses the router’s DHCP server. Assign reserved IP 
addresses to servers that require permanent IP settings. 
Use the Router as a DHCP Server
By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and 
default gateway addresses to all computers connected to the router’s LAN. The assigned 
default gateway address is the LAN address of the router. The 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 router are satisfactory.  
						

							genie Advanced Home

You can specify the pool of IP addresses to be assigned by setting the starting IP address 
and ending IP address. These addresses should be part of the same IP address subnet as 
the router’s LAN IP address. Using the default addressing scheme, you should define a 
range between 192.168.1.2 and 192.168.1.254, although you might want to save part of the 
range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
•An IP address from the range that you have defined
•Subnet mask
•Gateway IP address (the router’s LAN IP address)
•DNS server IP address (the router’s LAN IP address)
To use another device on your network as the DHCP server, or to manually configure the 
network settings of all of your computers, clear the Use Router as DHCP Server check box 
and click Apply. Otherwise, leave this check box selected. If this service is not enabled and 
no other DHCP server is available on your network, you need to set your computers’ IP 
addresses manually or they will not access the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always 
receives the same IP address each time it accesses the router’s DHCP 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. 
2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an 
IP address from the router’s LAN subnet, such as 192.168.1.x.) 
3. Type the MAC address of the computer or server.
Tip:If the computer is already on your network, you can copy its MAC 
address from the Attached Devices screen and paste it here.
4. Click Apply to enter the reserved address into the table. 
The reserved address is not assigned until the next time the computer contacts the 
router’s DHCP server. Reboot the computer or access its IP configuration and force a 
DHCP release and renew.
To edit or delete a reserved address entry, select the radio button next to the reserved 
address you want to edit or delete. Then click Edit or Delete.

Quality of Service (QoS) Setup
QoS is an advanced feature that can be used to prioritize some types of \
traffic ahead of 
others. The N600 Wireless Dual Band Router can provide QoS prioritization over the wireless 
link and on the Internet connection. To configure QoS, use the QoS Setup screen. 
Select 
Advanced > Setup > QoS Setup to display the following screen: 
Enable WMM QoS for Wireless Multimedia Applications
The N600 Wireless Dual Band 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 hav\
e to have WMM 
enabled. Legacy applications that do not support WMM and applications th\
at 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 
Enable WMM check box and clicking  Apply.
Set Up QoS for Internet Access
You can give prioritized Internet access to the following types of traffic:
•Specific applications
• Specific online games
• Individual Ethernet LAN ports of the router
• A specific device by MAC address 
						

							genie Advanced Home 46
N600 Wireless Dual Band Router WNDR3400v3 
To specify prioritization of traffic, you have to create a policy for the type of traffic and add the 
policy to the QoS Policy table in the QoS Setup screen. For convenience,\
 the QoS Policy 
table lists many common applications and online games that can benefit f\
rom QoS handling.
