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.
MAC Address: If you need to change the MAC address of the router's WAN-
side Ethernet interface, either type in an alternate MAC address (for example,
the MAC address of the router initially connected to the ISP) or click on Clone
Your PCs MAC Address.
