Change 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 a device in the data path
uses a lower MTU setting than the other devices, the data packets must be split or
“fragmented” to accommodate the device with the smallest MTU.
The best MTU setting for router 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 router 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 https://www.routerlogin.net.
Your browser might display a security message, which you can ignore. For more
information, see Log in to the local browser interface on page 16.
A login window opens.
3. Enter the router user name and password.
The user name is admin. The password is the one that you specified when you set
up your router. If you didn’t change the password, enter password. The user name
and password are case-sensitive.
The Dashboard displays.
