Leave the MTU unchanged unless one of these situations occurs:
• You have problems connecting to your ISP or other Internet service, and technical
support of either the ISP or NETGEAR recommends changing the MTU setting. These
web-based applications might require an MTU change:

- Y
ahoo email
- MSN portal
- America Online’
s DSL service
• Y
ou use VPN and have severe performance problems.
• Y
ou used a program to optimize MTU for performance reasons, and now you have
connectivity or performance problems.
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.
