You can check to see if all other clients that you plan to put on the network support WPA

or WPA2. You can do this by checking the manual that came with each device or by

checking the configuration software for the installed device. Look under

Security

or

Encryption

or

Setup

or

Advanced Features

. Most devices will support one of these

modes.



To change the Wireless Network Name (SSID) or Wireless Security Key

(Pre-Shared key) used by your Cable Modem/Router go to

Changing your

Wireless Network Name(SSID) and Pre-Shared Key

.



If any of the devices you want to connect to your wireless network do not support

WPA or WPA2, go to

Setting Up Security Using WEP

.



If you need to set up an unsecured network, see

Disabling Security

Changing your Wireless Network Name(SSID) and Pre-Shared

Key

1

Open the Zoom Configuration Manager by typing the following in your Web browser's

address bar:

2

In the

Login

dialog box, type the following User Name and Password in lower case,

then click

Login

.

User Name:

admin

Password:

admin

3

Click

Wireless

on the top menu.

4

Then click

Primary Network

on the left-side menu and in the text box labeled

Network Name (SSID)

, type an SSID of your choice. The SSID needs to be at least

one character long, and it’s probably best to pick a name that you’ll recognize as

yours.

5

To change the wireless security, start by setting all the following drop-down menus to

Disable: WPA, WPA-PSK, WPA2, and WPA2-PSK.

6

Then select Enable for the mode(s) you choose for setting wireless security.

Note:

To use WPA2 /WPA,

all

of the wireless devices on your network must support

either encryption method. In this case, enable:

o

WPA-PSK and WPA2-PSK (if you want to use a Pre-Shared Key)

or

o

WPA and WPA2 (use this only if your network uses a Radius Server. This

is very uncommon for a home network)

27

If you know that all your devices support the more secure WPA2 you can enable

WPA2 only (or WPA2-PSK if you want to use a Pre-Shared Key) instead of WPA and

WPA2.

7

In the

WPA Pre-Shared Key

text box (only if you selected an option requiring a

Pre-Shared Key), enter a passphrase of your choice (a minimum of 8 characters).

Write down this passphrase and put it where you can find it – on the bottom of the

Cable Modem/Router case, for instance.

8

Click

Apply

.

9

Now you need to set up each of your wireless devices with the SSID and passphrase

.

See

Chapter 3, Connecting other Devices to the Cable Modem/Router

for help on

connecting your wireless computers and devices.

Your security setup configuration is now complete!

Setting Up Security Using WEP

If

any

of your network devices DOES NOT support WPA or WPA2, you can use WEP to

configure network security. WEP can be configured two ways: 64-bit and 128-bit. 128-bit

WEP provides more security than 64-bit.

1

Open the Zoom Configuration Manager by typing the following in your Web browser's

address bar:

2

In the

Login

dialog box, type the following User Name and Password in lower case,

then click

Login

.

User Name:

admin

Password:

3

Click

Wireless

on the top menu.

4

Then click

Primary Network

on the left-side menu.

5

To change the wireless security, start by setting all the following drop-down menus to

Disable: WPA, WPA-PSK, WPA2, and WPA2-PSK

6

From the

WEP Encryption

drop-down menu, select

WEP-64 bit

(

or WEP-128

bit for

more security).

7

For

Network Key 1

, you can either enter your own WEP Key or you can have WEP

Keys generated.

If you are entering a network key of your choice, enter 13 ASCII characters or 26

hexadecimal digits for 128-bit encryption keys. Enter 5 ASCII characters or 10

hexadecimal digits for 64-bit encryption keys.

28

Otherwise, type something into the text box and click on

Generate WEP Keys

and

WEP Keys will automatically be generated for you.

Caution!

Do not click

Apply

until you have entered WEP Keys.

8

Click

Apply

.

9

Now you need to set up each of your wireless devices with the SSID and

passphrase. See

Chapter 3, Connecting other Devices to the Cable Modem/Router

for help on connecting your wireless computers and devices.

Your security setup configuration is now complete!

Disabling Security

If for some reason you need to set up an unsecured network, you will need to disable the

default security that is currently set up for your Cable Modem/Router. Follow the

instructions below.

1

Open the Zoom Configuration Manager by typing the following in your Web browser's

address bar:

2

In the

Login

dialog box, type the following User Name and Password in lower case,

then click

Now you need to set up each of your wireless devices with the correct SSID. See

Chapter 3, Connecting other Devices to the Cable Modem/Router

for help on

connecting your wireless computers and devices. Since Security is disabled you do

not need to configure security as described in Chapter 3.

That’s it! You have now disabled security.

Online Gaming

Read this chapter if you are going to use your Cable Modem/Router for online gaming.

Some online games require you to make changes to your firewall. This chapter explains

the different ways you can modify the firewall to allow your online gaming system access.

Gaming

If you are using your router for gaming, you may need to make changes to the router’s

firewall setting for the game to work. This is done by setting up a

DMZ

or using

Port

Triggering

so that the Cable Modem/Router’s firewall won’t block the other players

from your system during your gaming. The main difference between the methods is the

amount of access someone has to your system.

A DMZ allows access on all ports of the computer. Because of this, DMZ's are less

secure and should be used with caution with your computer. However DMZ’s work well

with gaming stations since security is not as much of an issue for gaming stations as it is

for computers.

Port triggering works by sensing when data is sent out on a predetermined outgoing port

and then automatically opening up the corresponding incoming port(s). It will

automatically forward the traffic on the incoming port to the computer that accessed the

outgoing port. If your game uses one port to send outgoing data and a different port (or

ports) for incoming data, you may want to use port triggering. You do not need to know

the IP address of your gaming station to set up port triggering. You will need to know

which ports your game requires you to open. This information is usually available with

your gaming software or you should be able to find it by searching for it on the web.



If you want to set up a DMZ for your gaming system, go to

DMZ Host

.



If you want to set up Port Triggering for your gaming system, go to

Port

Triggering

.

DMZ Host

The DMZ (De-militarized Zone) Host page allows you to configure a network device (e.g.

a PC or gaming system) to be visible directly to the Internet. This may be used if a game

doesn’t work with port triggers or if you are using a gaming system, where security is less

of a concern.

To set up a DMZ for your gaming system, you should first assign your gaming system a

static IP address.

Normally the Cable Modem/Router handles assigning IP addresses

to the different devices on your network using DHCP.

However DHCP does not

guarantee that your device will always get assigned the same IP address. The DMZ

needs to know the IP address of your gaming system to work, if the IP address changes

the DMZ will not work. Because your IP address could change over time you need to

assign a static IP on your gaming system. To setup a static IP address on your gaming

system, please refer to your gaming system’s documentation. If you no longer have the

documentation that came with your gaming system it usually can be found online.

When assigning a static IP address to your gaming system you should select an address

that is outside the IP addresses assigned by the Cable Modem/Router’s DHCP server.

By default the DHCP Server assigns addresses from 192.168.0.10 to 192.168.0.255.

We recommend using 192.168.0.5 as the static IP address for your gaming system.

To setup a

DMZ

for your gaming system:

1

Follow the instructions for your gaming system to assign a static IP address. We

recommend using 192.168.0.5.

2

Next access the Cable Modem/Routers configuration menu by launching a Web

browser on a computer that is directly connected to one of the router’s LAN ports.

3

In the browser address bar, type

and press the

Enter

key.

4

In the Login screen, enter:

default username:

admin

default password:

admin

Both the username and password are case sensitive. The default username and

password are printed on the bottom label of your unit.

5

Click the Login button to access the Cable Modem/Router. The

Status

page

appears.
