your ISP.
• Primary / Secondary DNS Address: Specify the primary and secondary IP address,
which is assigned by your ISP.
• 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.
• MAC Address: If you need to change the MAC address of the rounter'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.
• Click on the Save Settings button to store these settings.

6.2.4.2 DHCP CONNECTION (DYNAMIC IP ADDRESS)

• The WAN interface can be configured as a DHCP Client in which the ISP provides the
IP address to the device. This is also known as Dynamic IP.
• Select the Dynamic IP (DHCP) from the My Internet Connection drop-down list.
• Host Name: Specify a host name to define your system or connetion.
• Use Unicasting: This option is normally turned off, and should remain off as long as
the WAN-side DHCP server correctly provides an IP address to the router. However, if
the router cannot obtain an IP address from the DHCP server, the DHCP server may be
one that works better with unicast responses. In this case, turn the unicasting option on,
and observe whether the router can obtain an IP address. In this mode, the router
accepts unicast responses from the DHCP server instead of broadcast responses.
