Manage the MTU size
The maximum transmission unit (MTU) is the largest data packet a network device
transmits.
MTU concepts
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 maximum transmission unit (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 Internet service, and the technical
support of either the Internet service provider (ISP) or NETGEAR recommends
changing the MTU setting.
For example, if a secure website does not open, or displays only part of a web page,
you might need to change the MTU.
•
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.
CAUTION: 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.
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.

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 routers, adapters, and switches.
