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 has 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 have severe performance problems.
•You used a program to optimize MTU for performance reasons, and now you have 
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.
To change the MTU size:
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.

3. Enter the modem router user name and password.
The user name is  admin. 
 The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4.  Select  ADV
 ANCED > Setup > WAN Setup . 
5. In the MTU Size field, enter a value from 64 to 1500.
6.  Click the  Apply button.
Your change is 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. 
Table 1.  Common MTU sizes   
MTUApplication
1500 The largest Ethernet packet size. This setting is typical for connections that do not use 
PPPoE or VPN, and is the default value for NETGEAR modem routers, adapte\
rs, and 
switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you do not have large email attachments, for example.
