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 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
• 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.
Note: 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.
To change the MTU size:
1. Launch a web browser from a computer or mobile device that is connected to the
router network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the router admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. The user name and password are case-sensitive.
The Dashboard displays.
4. Select Settings > Setup > WAN Setup.
The WAN Setup page displays.
5. In the MTU Size field, enter a value from 64 to 1500.
6. Click the Apply button.
Your settings are saved.
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.
