Changing 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 any 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 one with the smallest MTU.

The best MTU setting for NETGEAR equipment is often just the default value, and changing

the value might fix one problem but cause another. Leave MTU unchanged unless one of

these situations occurs:

• You have problems connecting to your ISP, or other Internet service, and either the

technical support of the ISP or of NETGEAR recommends changing the MTU size. These

might require an MTU change:

-A secure Web site that will not open, or displays only part of a Web page

-Yahoo e-mail

-MSN

-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.
