• MTU Size - The normal MTU (Maximum Transmission Unit) value for most Ethernet
networks is 1500 Bytes. It is not recommended that you change the default MTU size
unless required by your ISP.
• Set DNS server manually - If your ISP gives you one or two DNS IP addresses, select
Set DNS server manually and enter the DNS Server and Secondary DNS Server into
the correct fields. Otherwise, the DNS servers will be assigned from ISP dynamically.
• Primary DNS - Enter the DNS IP address in dotted-decimal notation provided by
your ISP.
• Secondary DNS - Enter another DNS IP address in dotted-decimal notation
provided by your ISP.
• Host Name - This option specifies the name of the router.
• Get IP with Unicast DHCP - A few ISPs’ DHCP servers do not support the broadcast
applications. If you cannot get the IP address normally, you can choose this option. (It
is rarely required.)
Static IP
If your ISP provides a static or fixed IP address, subnet mask, default gateway and DNS
setting, please select Static IP.
