MTU: The Maximum Transmission Unit (MTU) is a parameter that determines the
largest packet size (in bytes) that the router will send to the WAN. If LAN devices
send larger packets, the router will break them into smaller packets. Ideally, you
should set this to match the MTU of the connection to your ISP. Typical values are
1500 bytes for an Ethernet connection and 1492 bytes for a PPPoE connection. If the
router's MTU is set too high, packets will be fragmented downstream. If the router's
MTU is set too low, the router will fragment packets unnecessarily and in extreme
cases may be unable to establish some connections. In either case, network
performance can suffer.
