13.In the Domain Name Server (DNS) Address section, select one of the following radio buttons:

•Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP automatically assigns this address.

•Use These DNS Servers. If you know that your ISP requires specific servers, select this option. Enter the IP address of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it also.

14.In the Router MAC Address section of the screen, select one of the following radio buttons:

•Use Default Address. Use the default MAC address.

•Use Computer MAC Address. The router captures and uses the MAC address of the computer that you are now using. You must use the one computer that the ISP allows.

•Use This MAC Address. Enter the MAC address that you want to use.

15.Click the Apply button. Your settings are saved.

16.Click the Test button to test your Internet connection.

Change the MTU Size

The maximum transmission unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If a device in the data path has a lower MTU setting than the other devices, the data packets must be split or “fragmented” to accommodate the device with the smallest MTU.

The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value fixes one problem but causes another. Leave the MTU unchanged unless one of these situations occurs:

•You experience problems connecting to your ISP or other Internet service, and the technical support of either the ISP or NETGEAR recommends changing the MTU setting. These web-based applications might require an MTU change:

-A secure website that does not open, or displays only part of a web page

-Yahoo email

-MSN portal

-America Online’s DSL service

•You use VPN and have severe performance problems.

•You used a program to optimize MTU for performance reasons, and now you have connectivity or performance problems.
