setting than the other devices, the data packets have to be split or “fragmented” to accommodate the device 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 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 have severe performance problems.

•You used a program to optimize MTU for performance reasons, and now you have connectivity or performance problems.

Note: An incorrect MTU setting can cause Internet communication problems such as the inability 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.

Table 9. Common MTU sizes

MTU	Application

1500	The largest Ethernet packet size and the default value. This is the typical setting for
	non-PPPoE, non-VPN connections, and is the default value for NETGEAR WiFi modem
	routers, adapters, and switches.

1492	Used in PPPoE environments.

1472	Maximum size to use for pinging. (Larger packets are fragmented.)

1468	Used in some DHCP environments.

1460	Usable by AOL if you do not have large email attachments, for example.

1436	Used in PPTP environments or with VPN.

1400	Maximum size for AOL DSL.

576	Typical value to connect to dial-up ISPs.
