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.

An incorrect MTU setting can cause Internet communication problems. For example,

you might not be able to access certain websites, frames within websites, secure

Note

To change the MTU size:

Launch a web browser from a WiFi-enabled computer or mobile device that is connected to the network.

Type

http://www.routerlogin.net

The BASIC Home page displays.

Select

ADVANCED > Setup > WAN Setup

The WAN Setup page displays.

In the

MTU Size

field, enter a value from 64 to 1500.

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.
