NETGEAR R6400 User Manual page 41

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.
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 window opens.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and
