User Guide

Use this section to set the maximum transmission unit (MTU) for your Ethernet WAN network. This is the maximum size of data packets, including headers, that can be transmitted. You might want to adjust the MTU when traffic is being tunneled or encrypted, or if you are noticing fragmentation issues.

NOTE: You can also adjust the MTU for Cellular on the Cellular tab and for the LAN connection on the LAN tab.

Maximum Transition Unit (MTU): The default (1500 bytes) is the recommended MTU for your FX4100 Ethernet WAN network. You can enter a different value between 1280 and 1500 bytes.
