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.
