These fields
display only if
your ISP
requires a
login.
Encapsulation
Encapsulation is a method for enclosing multiple protocols. PPP
stands for Point-to-Point Protocol. The choices are:
• PPPoE (PPP over Ethernet)
• PPPoA (PPP over ATM)
Login
The login name provided by your ISP. This is often an email address.
Password
The password that you use to log in to your ISP.
Idle Timeout (In
minutes)
If you want to change the login time-out, enter a new value in
minutes. This determines how long the wireless modem router keeps
the Internet connection active after there is no Internet activity from
the LAN. Entering a value of 0 (zero) means never log out.
Internet IP
Address
•
Get Dynamically from ISP
. Your ISP uses DHCP to assign your IP
address. Your ISP automatically assigns these addresses.
•
Use Static IP Address
. Enter the IP address, IP subnet mask, and
the gateway IP address that your ISP assigned. The gateway is the
ISP’s wireless modem router to which your wireless modem router
will connect.
This field displays only
if no login is required.
Use IP Over ATM (IPoA)
. Your ISP uses classical IP addresses (RFC
1577). Enter the IP address, IP subnet mask, and gateway IP
addresses that your ISP assigned.
Domain Name Server (DNS) Address
The DNS server is used to look up site addresses based on their
names.
•
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 does not
automatically transmit DNS addresses to the wireless modem
router during login, select this option, and enter the IP address of
your ISP’s primary DNS server. If a secondary DNS server address
is available, enter it also.

ADSL Settings
ADSL settings of your wireless modem router work fine for most ISPs. However, some ISPs
use a specific multiplexing method and virtual circuit number for the virtual path identifier
(VPI) and virtual channel identifier (VCI).
Note:
You must use the Setup Wizard to select the correct country for the
default ADSL settings to work.
NAT (Network Address Translation)
NAT automatically assigns private IP addresses (10.1.1.x) to
LAN-connected devices.
•
Enable
. Usually NAT is enabled.
•
Disable
. This disables NAT, but leaves the firewall active. Disable
NAT only if you are sure you do not need it. When NAT is disabled,
only standard routing is performed by this router. Classical routing
lets you directly manage the IP addresses that the wireless modem
router uses. Classical routing should be selected only by
experienced users.
1
•
Disable firewall
. This disables the firewall in addition to disabling
NAT. With the firewall disabled, the protections usually provided to
your network are disabled.
These fields
display only if
no login is
required.
Router MAC Address
The Ethernet MAC address used by the wireless modem router on
the Internet port. Some ISPs register the MAC address of the
network interface card in your computer when your account is first
opened. They will then accept traffic only from the MAC address of
that computer. This feature allows your wireless modem router to use
your computer’s MAC address (this is also called cloning).
•
Use Default Address
. Use the default MAC address.
•
Use Computer MAC Address
. The wireless modem router will
capture and use the MAC address of the computer that you are
now using. You must be using the one computer that is allowed by
the ISP.
•
Use This MAC Address
. Enter the MAC address that you want to
use.
1. Disabling NAT reboots the wireless modem router and resets its configuration settings to the factory defaults.
Disable NAT only if you plan to set up the wireless modem router in a setting where you will be manually
administering the IP address space on the LAN side of the router.

Read
Chapter 9, Troubleshooting
. If problems persist, register your NETGEAR product and
contact NETGEAR technical support.
Note:
If you cannot connect to the wireless router, check the Internet
Protocol (TCP/IP) properties in the Network Connections section of
your PC Control Panel. They should be set to obtain
both
IP and
DNS server addresses automatically.
Change Password and Login Time-Out
For security reasons, the wireless modem router has its own user name and password that
default to
admin
and
password
. You can and should change this password to a secure
password that is easy to remember. The ideal password contains no dictionary words from
any language and is a mixture of uppercase and lowercase letters, numbers, and symbols. It
can be up to 30 characters.

Note:
The router user name and password are not the same as the user
name and password for logging in to your Internet connection. See
Types of Logins
on page 34 for more information about login types.

1.
Select
Maintenance > Set Password
to display the following screen:
Figure 13.
Set router login password
2.
Enter the old password.
3.
Enter the new password twice.
4.
Change the login time-out to a value between 1 and 99 minutes if the default value of 5
minutes does not meet your needs.
The administrator’s login to the wireless modem router configuration times out after a
period of inactivity to prevent someone else from accessing the router interface when you
step away.
5.
Click
Apply
to save your changes.
After changing the password, you are required to log in again to continue the
configuration. If you have backed up the wireless modem router settings previously, you
should do a new backup so that the saved settings file includes the new password. See
Back Up
on page 67 for information about backing up your network configuration.
Log Out Manually
The router interface provides a Logout command at the bottom of the router menus. Log out
when you expect to be away from your computer for a relatively long period of time.
Types of Logins
There are three separate types of logins that have different purposes. It is important that you
understand the difference so that you know which login to use when.
•
Router login
logs you in to the router interface. See
Log In to the N600 Modem Router
on page 24 for details about this login.
