Changing the Maximum Transmission Unit
In most Ethernet networks, the maximum size of a packet that can be sent is 1500 bytes. A packet refers to a small chunk of data. The original data is divided into packets before being sent. The maximum transmission unit (MTU) may vary on each network. Change the settings of the machine as necessary. For more information, contact your network administrator.
