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 Use These DNS Servers - 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 your ISP.
) Note:
If you get address and find error when you go to a Web site, it is likely that your DNS servers are
set up improperly. You should contact your ISP to get DNS server addresses.
