ADSL Settings

DSL settings of your modem router work fine for most ISPs. However, some ISPs use a

multiplexing method and virtual circuit number for the virtual path identifier (VPI) and virtual

channel identifier (VCI).

Note:

You have to use the Setup Wizard to select the correct country for

the default DSL settings to work.

If your ISP provided you with a multiplexing method or VPI/VCI number, enter the setting:

1.

Select

Setup >

ADSL Settings

to display the following screen:

2.

In the Multiplexing Method drop-down list, select

LLC-based

or

VC-based

.

3.

For the VPI, type a number between 0 and 255. The default is 8 for the U.S. version, 0 for

the world wide version, and 1 for the German version.

4.

For the VCI, type a number between 32 and 65535. The default is 35 for the U.S. version,

38 for the worldwide version, and 32 for the German version.

5.

Click

Apply

.

Unsuccessful Internet Connection

1.

Review your settings to be sure that you have selected the correct options and typed

everything correctly.

2.

Contact your ISP to verify that you have the correct configuration information.

3.

Read

Chapter 9, Troubleshooting

. If problems persist, register your NETGEAR product and

contact NETGEAR Technical Support.

4.

If you cannot connect to the modem 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. See your computer documentation.

Change Password and Login Time-Out

For security reasons, the modem router has its own user name and password that default to

admin and password. You can and should change these to a secure user name and

password that are easy to remember. The ideal password contains no dictionary words from

any language and is a mixture of upper case and lower case letters, numbers, and symbols.

It can be up to 30 characters.

Note:

The modem 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

28 for more information

about login types.

1.

Select

Maintenance > Set Password

to display the following screen:

.

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 modem router configuration times out after a period of

inactivity to prevent someone else from accessing the modem 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 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

56 for information about backing up your network configuration.

Log Out Manually

The modem router interface provides a Logout command at the bottom of the modem 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.

•

Modem router login

logs you in to the modem router interface. See

Log In to the Modem

Router

on page

20 for details about this login.

•

ISP login

logs you in to your Internet service. Your service provider has provided you with

this login information in a letter or some other way. If you cannot find this login

information, contact your service provider.

•

Wi-Fi network name and passphrase

logs you in to your wireless network. This login is

preconfigured and can be found on the label on the bottom of your unit. See

Chapter 3,

Wireless Settings

, for more information.

Wireless Settings

Protecting your network

This chapter describes how to use the Wireless Settings screens to view and change (if needed)

your wireless network settings. Security features to prevent objectionable content from reaching

your PCs are covered in

Chapter 4, Content Filtering Settings

.

This chapter contains the following sections:

•

Wireless Adapter Compatibility

•

Preset Security

•

Wireless Adapter Compatibility

A wireless adapter is the wireless radio in your PC or laptop that lets the PC or laptop

connect to a wireless network. Most PCs and laptops come with an adapter already installed,

but if it is outdated or slow, you can purchase a USB adapter to plug into a USB port.

Make sure the wireless adapter in each computer in your wireless network supports the

same security settings as the modem router. See

Preset Security

on page

30 for information

about the modem router’s preconfigured security settings.

Note:

If you connect devices to your modem router using WPS as

described in

Wi-Fi Protected Setup (WPS) Method

on page

32,

those devices assume the security settings of the modem router.

Preset Security

The modem router comes with preset security. This means that the Wi-Fi network name

(SSID), passphrase, and security option (encryption protocol) are preset in the factory. You

can find the preset SSID and passphrase on the bottom of the unit.

•

Wi-Fi network name (SSID)

identifies your network so devices can find it.

•

Passphrase

controls access to your network. Devices that know the SSID and the

passphrase can find your wireless network and connect.

Note:

The preset SSID and passphrase are uniquely generated for every

device to protect and maximize your wireless security.

•

Security option

is the type of security protocol applied to your wireless network. The

security protocol in force encrypts data transmissions and ensures that only trusted

devices receive authorization to connect to your network. The preset security option is

WPA-PSK/WPA2-PSK mixed mode, described in

Wireless Security Options

on page

31.

The Wireless Settings screen lets you view and change the preset security settings.

However, NETGEAR recommends that you not change your preset security settings

.

If

you do decide to change your preset security settings, make a note of the new settings and

store it in a safe place where you can easily find it.

Security Basics

Unlike wired network data, wireless data transmissions extend beyond your walls and can be

received by any device with a compatible wireless adapter (radio). For this reason, it is very

important to maintain the preset security and understand the other security features available

to you. Besides the preset security settings described in the previous section, your modem

router has the security features described here and in

Chapter 4, Content Filtering Settings

.

•

Turn off wireless connectivity

•

Disable SSID broadcast

•

Restrict access by MAC address

Turn Off Wireless Connectivity

You can turn off the wireless connectivity of the modem router by pressing the Wireless

On/Off

button on its front panel

. For example, if you use your laptop to wirelessly connect

to your modem router and you take a business trip, you can turn off the wireless portion of the

modem router while you are traveling. Other members of your household who use computers

connected to the modem router through Ethernet cables can still use the modem router.
