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 a device in the data path uses a lower MTU 
setting than the other devices, the data packets must be split or “fragmented” to 
accommodate the device with the smallest MTU. 
The best MTU setting for NETGEAR equipment is often the default value. In some situations, 
changing the value fixes one problem but causes another. Leave the MTU unchanged unless 
one of these situations occurs:
•You experience 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
•You use VPN and experience severe performance problems.
•You used a program to optimize MTU for performance reasons and now you are 
experiencing connectivity or performance problems.
Note:An incorrect MTU setting can cause Internet communication 
problems. For example, you might not be able to access certain 
websites, frames within websites, secure login pages, or FTP or POP 
servers.

5. In the MTU Size field, enter a value from 64 to 1500.
6.  Click the  Apply button.
Your settings are saved.
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.

4.   Optimize Performance
You can set up the router to optimize performance for applications such as Internet gaming, 
high-definition video streaming, and VoIP communication. By default, the router uses Wi-Fi 
Multimedia Quality of Service (WMM QoS).
This chapter contains the following sections:
•Optimize Internet Streaming with QoS 
•Add QoS Rules by Service 
•Improve Network Connections with Universal Plug and Play 
•Wi-Fi Multimedia Quality of Service

Optimize Internet Streaming with QoS
You can use Quality of Service (QoS) to assign high priority to Interne\
t streaming, 
applications, and services.
Best effort traffic
Internet
High priority traffic
Figure 5. QoS can assign high priority to streaming from the Internet
NETGEAR recommends that you enable this feature only if you use streamin\
g Internet. 
When QoS assigns a high priority to streaming video, it also assigns low\
er priority to the rest 
of your Internet traffic. That means other tasks like downloading content from the Internet 
take longer.
To turn on Internet access QoS:
1.  Launch a web browser from a computer or wireless device that is connecte\
d to the 
network.
2.  In the address field of the web browser
 , enter http://www.routerlogin.net  or 
http://www.routerlogin.com .
