Chapter 1

Configuring Your Internet Connection

This chapter describes how to configure your ADSL2+ Modem Wireless Router Internet

connection. When you perform the initial configuration of your modem router using the Resource

CD as described in the NETGEAR Router Setup Manual, these settings are configured

automatically for you. This chapter provides further details about these settings, as well as

instructions on how to log in to the modem router for further configuration.

This chapter includes:

•“Logging In to the Modem Router”

•“Using the Smart Wizard to Set Up Your Router”

•“Logging In to the Modem Router”

•“Using the Setup Wizard to Auto-Detect Your Internet Connection”

•“Viewing or Manually Configuring Your ISP Settings”

•“Changing Your ADSL Settings”

•“How the Internet Connection Works”

What You Need Before You Begin

You need to prepare the following before you can set up your Product Family:

• Active Internet service provided by an ADSL account.

• The Internet Service Provider (ISP) configuration information for your ADSL account.

– ISP login name and password

– ISP Domain Name Server (DNS) addresses

– Fixed or static IP address

– Host and domain names

Note: NETGEAR recommends using the Smart Wizard on the Resource CD for initial

configuration, as described in the NETGEAR Wireless ADSL2+ Modem Router

Setup Manual.

v1.0, May 2008

• Depending on how your ISP set up your Internet account, you need to know one or more of

these settings:

– Virtual path identifier (VPI) and Virtual channel identifier (VCI) parameters

– Multiplexing method

– Host and domain names

• ASDL microfilters as explained in the NETGEAR Router Setup Manual.

• Your computer must be set up to use DHCP to get its TCP/IP configuration from the modem

router. This is usually the case. For help with DHCP, see the documentation that came with

your computer, or see the link to the online document in “Preparing a Computer for Network

Access” in Appendix C.

Your ISP should have provided you with all the information needed to connect to the Internet. If

you cannot locate this information, you can ask your ISP to provide it.

Using the Smart Wizard to Set Up Your Router

For first-time installation of your modem router, refer to the NETGEAR Router Setup Manual. The

Setup Manual explains how to launch the NETGEAR Smart Wizard on the Resource CD to step

you through the procedure to connect your router, modem, and computers. The Smart Wizard will

assist you in configuring your wireless settings and enabling wireless security for your network.

After initial configuration using the Setup Manual, you can use the information in this Reference

Manual to configure additional features of your wireless router.

For installation instructions in a language other than English, see the language options on the

Resource CD.

Note: The Smart Wizard cannot detect a PPTP connection with your ISP. If your ISP uses

this protocol, then you must configure your connection manually (see “Viewing or

Manually Configuring Your ISP Settings” on page 1-6).

You can log in to the modem router to view or change its settings.

To log in to the modem router:

1. Type http://routerlogin.net or http://192.168.0.1 in the address field of an Internet browser.

This login window opens:

2. Enter admin for the user name and password for the password, both in lower case letters.

3. Click OK. You will be logged in to your router’s main menu.

Note: Your computer must be configured for DHCP. For help with configuring DHCP, see

the documentation that came with your computer or see the link to the online

document in “Preparing a Computer for Network Access” in Appendix C.

Using the Setup Wizard to Auto-Detect Your Internet

Connection

The Setup Wizard searches your Internet connection for servers and protocols to determine your

ISP configuration.

To use the Setup Wizard to assist with configuration or to view the Internet connection settings:

1. Log in to the main menu following the steps described in “Logging In to the Modem Router”

on page 1-3

2. Select Setup Wizard to go to the Setup Wizard screen:

3. Select your Country and Language:

•Country. It is important to specify the location where the modem router will operate so

that the Internet connection will work correctly.

•Language. You can select a language from the drop-down list.

4. Select your Auto-Connection Type: Auto-Detect Connection Type. If you want to change the

settings for the Internet connection, select Yes or No, and then click Next.

•Yes. Let the modem router Setup Wizard auto-detect the type of Internet connection that

you have and configure it.

Note: The wizard cannot detect a PPTP connection with your ISP. If your ISP uses this

protocol, then you must configure your connection manually (see “Viewing or

Manually Configuring Your ISP Settings” on page 1-6).

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 that your ISP

assigned. Also enter the IP subnet mask and the gateway IP

address. The gateway is the ISP’s modem router to which

your modem router will connect.

•Use IP Over ATM (IFoA). 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 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.

NAT (Net 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 that you do not require it.

When NAT is disabled, only standard routing is performed

by this router. Classical routing lets you directly manage the

IP addresses that the DG834G v5 uses. Classical routing

should be selected only by experienced users.a

•Disable Firewall. This disables the firewall in addition to

disabling NAT. With the firewall disabled, the protections

usually provided to your network are disabled.

v1.0, May 2008

Changing Your ADSL Settings

The default ADSL settings of your 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).

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

1. From the main menu, select ADSL Settings.

2. In the Multiplexing Method drop-down list, select LLC-based or VC-based.

3. Type a number between 0 and 255 for the VPI. The default is 8.

This field

appears only if

no login is

required.

Router MAC Address The Ethernet MAC address that will be used by the modem

router on the Internet port. Some ISPs register the Ethernet

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 modem router to masquerade as that computer by

“cloning” its MAC address.

•Use Default Address. Use the default MAC address.

•Use Computer MAC Address. The 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.

a. Disable NAT only if you plan to install the modem router in a setting where you will be manually administering the IP address

space on the LAN side of the router.

Note: For information about how to install ADSL filters, see the NETGEAR Router Setup

Manual.

Note: You must use the Setup Wizard to select the correct country for the default ADSL

settings to work.
