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.
