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.
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 find error when you go to a Web site after entering the DNS addresses, it is likely that your
DNS servers are set up improperly. You should contact your ISP to get DNS server addresses.
