Section 3 - Configuration
My Internet Connection is: Dynamic IP (DHCP)
The default WAN configuration for this router is Dynamic IP (DHCP). This
option allows the router to obtain an IP address automatically from the de-
vice that is connected to the Internet port.
Note: If you're not sure about the type of Internet connection you have,
please contact your Internet Service Provider (ISP) for assistance.
After selecting Dynamic IP, the following parameters will be available for
configuration:
Host Name: The host name is optional but may be required by some
ISPs. Leave blank if you are not sure.
Use Unicasting: Tick this option if your ISP uses the unicast method to
provide IP addresses.
Primary DNS:
Enter the primary DNS IP address used here.
Secondary DNS: Enter the secondary DNS IP address used here. This field
is normally optional. Only one DNS address is required
for a functional Internet connection, but using a second
DNS address provides more stability.
MTU: Maximum Transmission Unit - you may need to change
the MTU for optimal performance with your specific ISP.
1500 is the default MTU.
MAC Address: The default MAC address is set to the Internet port's
physical interface MAC address on the broadband router.
It is not recommended that you change the default MAC
address unless required by your ISP. You can use the
Clone Your PC's MAC Address button to replace the In-
ternet port's MAC address with the MAC address of your
Ethernet card.
