Netgear D6400 – AC1600 WiFi VDSL/ADSL Modem Router—802.11ac Dual Band Gigabit User Manual

The modem router automatically detects the information in the following fields:

Router’s IPv6 Address On WAN. This field shows the IPv6 address that is acquired 
for the modem router’s WAN (or Internet) interface. The number after the slash (/) is 
the length of the prefix, which is also indicated by the underline (_) under the IPv6 
address. If no address is acquired, the field displays Not Available.

Router’s IPv6 Address On LAN. This field shows the IPv6 address that is acquired 
for the modem router’s LAN interface. The number after the slash (/) is the length of 
the prefix, which is also indicated by the underline (_) under the IPv6 address. If no 
address is acquired, the field displays Not Available.

In the Login field, enter the login information for the ISP connection.

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 enter JerAB in this field. Some ISPs (such as 
Earthlink) require that you use your full email address when you log in. If your ISP 
requires your full email address, enter it in this field.

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

In the Service Name field, enter a service name.

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

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