How to Access the Web-based Utility

Wireless-G Cable Gateway

How to Access the Web-based Utility

To access the web-based utility, launch Internet Explorer or Netscape Navigator, and enter the Gateway’s default

IP address,

192.168.0.1

, in the Address field. Then press

Enter.

A password request page will appear. (Non-Windows XP users will see a similar screen.) Leave the

User Name

field blank, and enter

admin

(the default password) in the

Password

field.

Then click the

OK

button.

The Setup Tab

The Basic Setup Tab

The first screen that appears is the Basic Setup tab. This tab allows you to change the Gateway's general

settings. Change these settings as described here and click the

Save Settings

button to save your changes or

Cancel Changes

to cancel your changes.

Internet Setup

Internet Connection Type. The Gateway supports Dynamic IP and Static IP. Each Basic Setup screen and

available features will differ depending on what type you select.

Dynamic IP

IP Settings. Select

Obtain IP Address Automatically

if your ISP says you are connecting through a dynamic

IP address.

Static IP

If you are required to use a permanent (static) IP address to connect to the Internet, then select

Set Static IP

Manually

.

•

Internet IP Address. This is the Gateway’s IP address, when seen from the WAN, or the Internet. Your ISP

will provide you with the IP Address you need to specify here.

•

Subnet Mask. This is the Gateway’s Subnet Mask. Your ISP will provide you with the Subnet Mask.

Chapter 5: Configuring the Wireless-G Cable Gateway

The Setup Tab

Wireless-G Cable Gateway

•

Default Gateway. Your ISP will provide you with the default Gateway Address, which is the ISP server’s IP

address.

•

Primary DNS. (Required) and Secondary DNS (Optional). Your ISP will provide you with at least one DNS

(Domain Name System) Server IP Address.

When finished making your changes on this tab, click the

Save Settings

button to save these changes, or

click the

Cancel Changes

button to undo your changes.

Optional Settings (Required by some ISPs)

•

Host Name and Domain Name. These fields allow you to supply a host and domain name for the Gateway.

Some ISPs require these names as identification. You may have to check with your ISP to see if your

broadband Internet service has been configured with a host and domain name. In most cases, leaving these

fields blank will work.

Network Setup

•

Gateway IP. The value for the Gateway’s Local IP Address are shown here.

•

Network Address Server Settings (DHCP). A Dynamic Host Configuration Protocol (DHCP) server automatically

assigns an IP address to each computer on your network for you. Unless you already have one, it is highly

recommended that you leave the Gateway enabled as a DHCP server.

•

Local DHCP Server. If you enable the DHCP Server for the Local DHCP server, enter the IP address for the

DHCP server in the fields provided.

•

Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. This value

must be 192.168.0.2 or greater, because the default IP address for the Gateway is 192.168.0.1.

•

Number of Address. Enter the maximum number of computers that you want the DHCP server to assign IP

addresses to. This number cannot be greater than 253. By default, the range is 192.168.0.10 to

192.168.0.254.

•

IP Address Range. The range of DHCP addresses is displayed here.

The Wireless Tab

Wireless-G Cable Gateway

The Wireless Tab

Basic Wireless Settings Tab

There are two ways to configure the Gateway’s wireless settings, SecureEasySetup and manual configuration. If

you have other SecureEasySetup devices, such as notebook adapters or printers, then you can use the Gateway’s

SecureEasySetup feature to configure your wireless network. Follow the instructions for the SecureEasySetup

button feature.

If you do not have other SecureEasySetup devices, then enter your wireless settings on this screen.

•

Wireless Network. Select

Enable

to enable your wireless network, or select

Disable

to disable it.

•

Wireless Network Name (SSID). Enter the name for your wireless network into the field. The SSID must be

identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric

characters, which may be any keyboard character. Linksys recommends that you change the default SSID

(

linksys

) to a unique name of your choice.

•

Wireless Channel. Select the appropriate channel from the list provided to correspond with your network

settings. All devices in your wireless network must use the same channel in order to function correctly.

Linksys wireless clients will automatically detect the wireless channel of the Gateway.

•

Wireless Network Type. If you have 802.11g and 802.11b devices in your network, then keep the default

setting,

Mixed

. If you have only 802.11g devices, select

802.11g

. If you have only 802.11b devices, select

802.11b

. If you want to disable wireless networking, select

Disabled

.

•

Current Encryption. Your wireless security encryption method will be displayed here.

•

SecureEasySetup Button. The status of the Gateway’s SecureEasySetup feature is displayed here. If you want

to use the Gateway’s SecureEasySetup feature, click the

SecureEasySetup

button.

You will be asked to press the SecureEasySetup button (hardware or software) on your wireless client

(computer or other network device) within two minutes to complete the SecureEasySetup process.

Figure 5-4: Basic Wireless Settings

NOTE:

SecureEasySetup uses WPA Personal encryption. If your current

wireless devices do not support WPA Personal security, then you cannot use

SecureEasySetup on your network. You will need to manually configure your

network security using the encryption supported by your existing devices.

When the SecureEasySetup process is complete, the

Basic Wireless Settings

screen will appear, and the

Current Encryption and Status information will be updated.

Then repeat this procedure for each additional SecureEasySetup device.

If you have non-SecureEasySetup devices to configure, then write down the Wireless Network Name (SSID)

for the Gateway. Click the

Wireless Security

tab. The Gateway’s WPA-Personal settings will appear on the

Wireless Security

screen. Write down the Passphrase for the Gateway. When you configure the wireless

settings for your non-SecureEasySetup devices, enter the Gateway’s Network Name (SSID) and Passphrase

when you are asked for them.

•

Reset Security

. If you want to reset the Gateway to its factory default wireless settings (SSID:

linksys

and

wireless security disabled), then click the

Reset Security

button.

After the Gateway’s SSID has been reset and its security disabled, you can click the SecureEasySetup button

to configure your wireless network with a new SSID and Passphrase, or you can manually enter new settings

on the

Basic Wireless Settings

and

Wireless Security

screens.

When finished making your changes on this tab, click the

Save Settings

button to save these changes, or click

the

Cancel Changes

button to undo your changes.

Wireless Security Tab

The Wireless Security settings configure the security of your wireless network. There are six wireless security

mode options supported by the Gateway: WPA-Personal, WPA2-Personal, WPA-Enterprise, WPA2-Enterprise,

RADIUS, and WEP. (WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP

encryption. WPA2 is a stronger version of WPA. WEP stands for Wired Equivalent Privacy, while RADIUS stands for

Remote Authentication Dial-In User Service.) These are briefly discussed here. For detailed instructions on

configuring wireless security for the Gateway, turn to “Appendix B: Wireless Security.” If you want to disable

wireless security, select

Disabled

from the drop-down menu for Security Mode.

•

Wireless SSID Broadcast. When wireless clients survey the local area for wireless networks to associate with,

they will detect the SSID broadcast by the Gateway. To broadcast the Gateway's SSID, keep the default

setting,

Enable

. If you do not want to broadcast the Gateway's SSID, then select

Disable

.

Figure 5-7: Wireless Security

NOTE:

Some devices may call the Passphrase a Pre-Shared Key instead. They are different

names for the same key.
