This is usually the name that you use in your email address. For example, if your main mail account is JerAB@ISP.com, you would type JerAB in this field. Some ISPs (like Mindspring, Earthlink, and T-DSL) require that you use your full email address when you log in. If your ISP requires your full email address, type it in this field.

7.In the Password field, enter the password for the ISP connection.

8.In the Service Name field, enter a service name.

If your ISP did not provide a service name, leave this field blank.

Note: The default setting of the Connection Mode field is Always On to provide a steady IPv6 connection. The router never terminates the connection. If the connection is terminated, for example, when the modem is turned off, the router attempts to reestablish the connection immediately after the PPPoE connection becomes available again.

9.Specify how the router assigns IPv6 addresses to the devices on your home network (the LAN) by selecting one of the following radio buttons:

•Use DHCP Server. This method passes more information to LAN devices, but some IPv6 systems might not support the DHCv6 client function.

•Auto Config. This is the default setting.

10.(Optional) Select the Use This Interface ID check box and specify the interface ID that you want to be used for the IPv6 address of the router’s LAN interface.

If you do not specify an ID here, the router generates one automatically from its MAC address.

11.Click the Apply button.

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
