WAN MTU Setup
The MTU (maximum transmission unit) is the largest data packet a network device transmits.
The normal MTU value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE
connections. For some ISPs, you might need to change the MTU. This is rarely required, and
should not be done unless you are sure it is necessary for your ISP connection. 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 has a smaller MTU value than the other
devices, the data packets have to be "fragmented" to accommodate the device with the smallest
MTU value.
The best MTU value is often just the factory default value. In some situations, changing the MTU
value fixes one problem but causes another. Leave the MTU unchanged unless one of these
situations occurs:
A. You have problems connecting to your ISP or other Internet service, and either your ISP or our
technical support suggests changing the MTU value. Below web-based applications might require
an MTU change:
