2. Enter the MTU Size. The MTU (Maximum Transmit Unit) is the size of the largest packet that
can be sent over the network. The standard MTU value for Ethernet networks is usually 1500
Bytes and for PPPoE connections, it is 1492 Bytes. Unless a change is required by your ISP,
we recommend that the MTU value be left as is.
3. Enter your Port Speed. Most new devices with Ethernet ports run at full-duplex, 100Mbps
modes. The DGFV338 can automatically negotiate the speed with the other end of the
Ethernet connection. However, if the Internet LED blinks continuously, you may need to set
the port speed manually. This could occur with some older broadband modems. If the Ethernet
port of the broadband modem supports 100BaseT, select 100BaseT; otherwise, select 10BaseT.
Use the half-duplex settings if full-duplex modes do not function properly.
4. Enter the Router's 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 and
expects a specific MAC address, then select either:
– Use This Computer's MAC address, where the DGFV338 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 12 hexadecimal digits, such as 01:23:45:67:89:AB.
