•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. For instance, 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.

Table 2. Common MTU Sizes

MTU	Application

1500	The largest Ethernet packet size and the default value. This setting is typical for
	connections that do not use PPPoE or VPN, and is the default value for NETGEAR
	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.
