MTU Settings
Maximum Transmission
Unit
The maximum transmission unit (MTU) is the largest physical packet size that a
network can transmit. Packets that are larger than the MTU value are divided
into smaller packets before they are sent, an action that prolongs the
transmission process. For most Ethernet networks the MTU value is
1500 Bytes, which is the default setting.
Note: NETGEAR recommends synchronizing the STM’s MTU setting with that
of your network to prevent delays in transmission.
