Getting to Know Your Wireless Router

Congratulations on your purchase of a NETGEAR® high-speed wireless router, the 54 Mbps

Wireless ADSL2+ Modem Router Model DG834G.

Before you begin installing your router, check the package contents (see “Unpacking Your New

Router” on page 1). Become familiar with the front and back panels of your router—especially the

LEDs—and the important information on the router label (see “Hardware Features” on page 2).

Then, read the section on “Positioning Your Wireless Router” on page 5 to ensure that you have

selected the best location to install your router.

This chapter describes how to set up the router on your Local Area Network (LAN) and connect to

the Internet. It describes how to set up your wireless modem router for Internet access and

configure basic wireless connectivity.

Unpacking Your New Router

Your router should contain the following items:

• Wireless Modem Router

• AC power adapter (varies by region)

• Category 5 (Cat 5) Ethernet cable

• Telephone cable with RJ-11 connector

• Microfilters (quantity and type vary by region)

•Resource CD, including:

– The Smart Wizard Installation Assistant

– This manual

• Warranty and Support Information cards

If any of the parts are incorrect, missing, or damaged, contact your NETGEAR dealer. Keep the

carton, including the original packing materials, in case you need to return the product for repair.

Hardware Features

Before you install and connect your router, take a moment to become familiar with the front and

back panels of the router—especially the LEDs on the front panel.

Front Panel

The wireless modem router front panel shown below contains status LEDs.

You can use the LEDs to verify various conditions. The following table describes each LED..

Multiplexer (DSLAM).

The ADSL is synchronizing with the DSLAM. The LED blinks at a rate

of 2 Hz when the wireless modem router is trying to detect a carrier

signal, and blinks at 4 Hz when the carrier has been detected and the

wireless modem router is trying to train.

No link is detected on the ADSL port, or the wireless modem router is

powered off.

5. Internet

The wireless modem router is connected to the Internet. The LED will

remain solid green if the Internet session is dropped due to an idle

time-out, but an ADSL connection is still present. If the session is

dropped for any other reason, the LED will turn off.

The wireless modem router is connected to the Internet and traffic is

passing through the device.

The wireless modem router attempted to connect to the Internet but

failed.

The wireless modem router is powered off, or in bridged mode, or

there is no ADSL connection.

The ports on the router are color-coded to distinguish your Internet port from the other four ports

that connect to the wired computer(s) on your LAN. The rear panel contains the following

elements:

1. Wireless antenna

2. AC power adapter input

3. Power switch

4. Four local Ethernet RJ-45 LAN ports for connecting the router to the local computers

5. RJ-11 ADSL port for connecting the router to an ADSL line

Router Side Panel

The side panel of the router has a WPS button and a Wireless button.

•WPS. You can use the Wi-Fi Protected Setup (WPS) feature with clients on the network that

are Wi-Fi certified and WPA capable. See “Using Push 'N' Connect (WPS) to Configure Your

Wireless Network” on page 21.

•Wireless. By default, the wireless modem router is set up to work as a wireless access point.

Pressing this button turns the wireless access point feature off and on. You can also do this

through the Wireless Settings screen (see the link to your User Manual on the Resource CD.)

•Factory default settings. Pressing both buttons at the same time resets the unit the factory

default settings.

Router Label

The label on the back of the wireless modem router shows the router’s MAC address, serial

number, and factory default login information.

Positioning Your Wireless Router

The wireless modem router lets you access your network from virtually anywhere within the

operating range of your wireless network. However, the operating distance or range of your

wireless connection can vary significantly depending on the physical placement of your router. For

example, the thickness and number of walls the wireless signal must pass through may limit the

range. For best results, place your router:

• Near the center of the area where your computers and other devices will operate, preferably

within line of sight to your wireless devices.

• Accessible to an AC power outlet and near Ethernet cables for wired computers.

• In an elevated location such as a high shelf, keeping the number of walls and ceilings between

the wireless modem router and your other devices to a minimum.

• Away from electrical devices which are potential sources of interference, such as ceiling fans,

home security systems, microwaves, or the base for a cordless phone.

Figure 4

6 Getting to Know Your Wireless Router

• Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large

expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and

concrete can also affect your wireless signal.

Installing Your Wireless Modem Router

To help you set up your router and get on the Internet quickly, the Resource CD contains a Smart

Wizard™. The Smart Wizard walks you through the steps required to connect your router,

microfilters, and PC(s); configure your wireless settings; and enable wireless security for your

network. When you have finished, you will be Internet ready!

You can set up your wireless modem router using one of two methods:.

•Smart Wizard Setup: The Smart Wizard setup is available on your Resource CD. See

“Installing Your Router Using the Smart Wizard” on page 9 to use the Smart Wizard.

– This is the easiest option. The wizard guides you through the setup process. It automates

many of the steps and verifies that the steps have been successfully completed.

– Smart Wizard requires a PC running Microsoft Windows..

•Manual Setup: If you cannot or prefer not to use the Smart Wizard, see “Installing Your

Router Manually (Advanced, Mac, and Linux Users)” on page 11. For example, if you are

connecting to a Mac, are using a Linux operating system, or are technically knowledgeable,

select this option. If you choose to use this option and install your router manually, for best

results, install and set up your router in this order:

Failure to follow these guidelines can result in significant performance degradation

or an inability to wirelessly connect to the Internet.

If you have a Macintosh or Linux system, you need to use the manual installation

method (see “Installing Your Router Manually (Advanced, Mac, and Linux Users)”

on page 11).

Before running the Smart Wizard on a corporate PC to set up your home

router, check with your company’s network support staff. Corporate

network settings or Virtual Private Network (VPN) client software may

conflict with the default settings of a home router. If you are unsure about

whether there might be a conflict, use a different computer.
