MTU Size - The normal MTU (Maximum Transmit Unit) value for most Ethernet networks
is 1500 bytes. For some ISPs, you may need to modify the MTU. But this is rarely
required, and should not be done unless you are sure it is necessary for your ISP
connection.
Primary DNS / Secondary DNS - (Optional) Enter the DNS IP address in dotted-decimal
notation provided by your ISP. Note: If you get 'Address not found' errors 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.
