MTU Size (in bytes) - 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
corresponding fields. Otherwise, the DNS servers will be assigned dynamically from your
ISP.
Note:
If you get Address not found error when you access a Web site, it is likely that your DNS
servers are set up improperly. You should contact your ISP to get the correct DNS server
addresses.
Host Name - This option specifies the Host 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.)
2. If your ISP provides a static or fixed IP Address, Subnet Mask, Gateway and DNS setting,
select Static IP. The Static IP settings page will appear, shown in Figure 4-11.
