¾ User Name & Password - Enter the user name and password for 802.1x
authentication provided by your ISP
¾ Host Name - Enter the host name.
¾ MTU Size - The normal MTU (Maximum Transmission Unit) value for most Ethernet
networks is 1500 Bytes. For some ISPs you need to reduce the MTU. But this is
rarely required, and should not be done unless you are sure it is necessary for your
ISP connection.
¾ Primary DNS & Secondary DNS - If your ISP gives you one or two DNS addresses,
select Use These DNS Servers and enter the primary and secondary addresses
into the correct fields. Otherwise, the DNS servers will be assigned dynamically from
ISP.
¾ 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. (You don’t need select this option generally).
