• MTU Size. The normal MTU value for most networks is 1500 Bytes, or 1492 for PPPoE
connections. For some ISPs, you may need to reduce the MTU size. However, this is rarely
required and should not be attempted unless you are sure it is necessary for your ISP
connection.
• Port Speed (Ethernet only). Usually, your router can automatically determine the connection
speed of the 10/100 port. If you cannot establish an Internet connection and the Internet LED
blinks continuously, manually select the port speed.
If you know your Ethernet port on your broadband modem supports 100BaseT, select 100M;
otherwise, select 10M. Use the half-duplex settings unless you are sure you need full duplex.
• Router MAC Address. Each computer or router on your network has a unique 32-bit local
Ethernet address, known as the Media Access Control (MAC) address. In most cases the
default Use Default Address will suffice. If your ISP requires MAC authentication, then select
either:
– Use This Computer's MAC address, where the router will use the MAC address of the
computer you are now using, or
– Use This MAC Address, where you manually enter the MAC address that your ISP
expects. The format is XX:XX:XX:XX:XX:XX.
