c.

Connect the gateway to you computer.

—

If you will connect with the Ethernet cable, follow the instructions below.

—

If you will connect with the USB cable, skip to step d below.

Connect the gateway to you computer using the Ethernet cable included in the box

from

your CG814WG v2’s LAN port (B

)

to the Ethernet adapter in your computer.

Figure 3-2:

Connect a PC to the gateway

The CG814WG v2 Gateway incorporates Auto Uplink

TM

technology. Each LOCAL

Ethernet port will automatically sense whether the cable plugged into the port should have

a “normal” connection (e.g., connecting to a PC) or an “uplink” connection (e.g.,

connecting to a switch or hub). That port will then configure itself to the correct

configuration. This feature also eliminates the need to worry about crossover cables, as

Auto Uplink will accommodate either type of cable to make the right connection.

Note:

Set up the CG814WG v2 Gateway using either an Ethernet or USB connection to

your computer first, then configure the wireless settings. Detailed instructions on

configuring your wireless devices for TCP/IP networking are provided in the next

chapter.

d.

To connect your computer to the modem via USB you must install the USB driver. Insert

the

Resource CD

that came with your gateway into the CD drive of your computer.

Install the USB driver.

–

Connect the USB cable to your modem and plug in the AC power for the gateway.

–

Use the USB cable to connect your computer to the gateway.

–

The found new hardware Windows installation wizard will prompt you for the drivers.

Browse to the

Resource CD

and install the USB driver by clicking through the Windows

wizard prompts.

e.

Plug in your CG814WG v2 and wait about 30 seconds for the lights to stop blinking.

f.

Now, turn on your computer. If software usually logs you in to your Internet connection,

do not run that software or cancel it if it starts automatically.

g.

Verify the following:

The power light is lit after turning on the gateway.

The cable link light is solid green, indicating a link has been established to the cable

network.

The local lights are lit for any connected computers.

Note:

The USB connection option is only available for Windows PCs. Also, Windows

95 does not support USB without special operating system upgrades and patches.

2.

Log in to the Gateway.

Note:

To connect to the gateway, your computer needs to be configured to obtain an IP

address automatically via DHCP. For instructions on how to do this, please see

Appendix C,

“Preparing Your Network”

.

a.

Using the computer that you first used to access your cable modem Internet service,

connect to the gateway by typing

http://192.168.0.1

in the address field of your Internet

browser.

A login window opens as shown below:

Figure 3-4:

Login window

b.

For security reasons, the gateway has two sets of user names and passwords: one for a

parent and one for children. Only the parent’s login can be used to set up Parental Control

and MAC Filtering. The child’s login can configure all other features of the gateway.

When prompted to log in as the parent, enter

superuser

for the user name and

password

for the password, both in lower case letters.

When prompted to log in as the child, enter

admin

for the user name and

password

for the

password, both in lower case letters.

c.

After logging in, you will see the Basic Settings shown in

Figure 3-5

below.

Note:

If you were unable to connect to the gateway, please refer to

“Basic Functions” on

page 7-1

.

a.

You are now connected to the gateway. Click the Basic Settings link on the upper left of

the main menu. You are now connected to the gateway’s

Basic Settings

page, shown

below.

Figure 3-5:

Basic Settings page

You are ready to configure your gateway to connect to the Internet.

b.

Select Dynamic or Static IP Address:

If your service provider assigns your IP address automatically through DHCP, select

“Dynamic IP”. If your service provider has assigned you a permanent, fixed (static) IP

address for your PC, select “Static IP”.

If you select Static IP, enter the IP address that your ISP assigned. Also enter the Static IP

Mask (also known as netmask), Gateway IP address and Domain Name Server (DNS)

Address.

–

The Gateway is the ISP’s router to which your gateway will connect.

–

A DNS server is a host on the Internet that translates Internet names (such as

www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP

address of one or two DNS servers to your gateway during login. If the ISP does not

transfer an address, you must obtain it from the ISP and enter it manually here. If you

enter an address here, you should reboot your PCs after configuring the gateway.

c.

Wireless Configuration

This chapter describes how to configure the wireless features of your CG814WG v2 Wireless

Cable Modem Gateway.

Considerations For A Wireless Network

In planning your wireless network, you should consider the level of security required. You should

also select the physical placement of your gateway in order to maximize the network speed. For

further information on wireless networking, refer to

“Wireless Networking Overview”

in

Appendix B, “Networks, Routing, and Firewall Basics”

.”

Implement Appropriate Security

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

can be received by anyone with a compatible adapter. For this reason, use the security features of

your wireless equipment. Restricting access by MAC address filtering adds an obstacle to

unwanted users joining your network. To hinder a determined eavesdropper, you should use one of

Wired Equivalent Privacy (WEP) data encryption options.

Note:

If you are configuring the gateway from a wireless PC and you change the

gateway’s SSID, channel, or WEP settings, you will lose your wireless connection when

you click Apply. You must then change the wireless settings of your PC to match the

gateway’s new settings.
