Wireless-G Broadband Router with 2 Phone Ports

The Setup Tab - Advanced Routing

The

Advanced Routing

screen allows you to configure the Network Address Translation (NAT), dynamic routing,

and static routing settings.

Advanced Routing

NAT

. NAT is a security feature that is enabled by default. It enables the Router to translate IP addresses of your

local area network to a different IP address for the Internet. To disable NAT, click the

Disable

radio button. (When

NAT is disabled, the DHCP server feature is also disabled.)

Dynamic Routing

. This feature enables the Router to automatically adjust to physical changes in the network’s

layout and exchange routing tables with the other router(s). The Router determines the network packets’ route

based on the fewest number of hops between the source and the destination.

Transmit RIP Version

. To use dynamic routing for transmission of network data, select the protocol you want:

RIP1

,

RIP1-Compatible

, or

RIP2

.

Receive RIP Version

. To use dynamic routing for reception of network data, select the protocol you want,

RIP1

or

RIP2

.

Static Routing

. Use this feature to set up a static router between the Router and another network. (A static route

is a pre-determined pathway that network information must travel to reach a specific host or network.) To create

a static route, alter the following settings:

Select Entry

. Select the number of the static route from the drop-down menu. The Router supports up to 20

static route entries.

Enter Route Name

. Enter a name for the static route, using a maximum of 25 alphanumeric characters.

Destination LAN IP

. The Destination LAN IP Address is the address of the remote network or host to which

you want to assign a static route. Enter the IP address of the host for which you wish to create a static route.

Subnet Mask

. The Subnet Mask determines which portion of a Destination IP address is the network portion,

and which portion is the host portion.

Gateway

. This is the IP address of the gateway device that allows for contact between the Router and the

remote network or host.

Hop Count

. This determines the maximum number of steps between network nodes that data packets will

travel. A node is any device on the network, such as PCs, print servers, routers, etc.

Show Routing Table

. Click the

button to open a screen displaying how data is routed

through your local network. For each route, the Destination LAN IP address, Subnet Mask, Default Gateway, Hop

Count, and Interface are displayed. Click the

The Wireless Tab - Basic Wireless Settings

The basic settings for wireless networking are set on this screen.

Wireless Network Mode

. From this drop-down menu, you can select the wireless standards running on your

network. If you have both 802.11g and 802.11b devices in your network, keep the default setting,

Mixed

. If you

have only 802.11g devices, select

G-Only

. If you have only 802.11b devices, select

B-Only

. If you do not have any

802.11g and 802.11b devices in your network, select

Disable

.

Wireless Network Name (SSID)

. The SSID is the network name shared among all points in a wireless network.

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

characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your

wireless network. For added security, you should change the default SSID (

linksys

) to a unique name.

Wireless Channel

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

settings. All devices in your wireless network must be broadcast on the same channel in order to function

correctly.

Wireless SSID Broadcast

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

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

Enable

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

Disable

.

Wireless-G Broadband Router with 2 Phone Ports

The Wireless Tab - Wireless Security

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

mode options supported by the Router: WPA Pre-Shared Key, WPA RADIUS, and WEP. (WPA stands for Wi-Fi

Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent

Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These three are briefly discussed

here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix B: Wireless

Security.”

WPA Pre-Shared Key

. WPA gives you one encryption method, TKIP, with dynamic encryption keys. Select

TKIP

from the

WPA Algorithm

drop-down menu. Enter a WPA Shared Key of 8-32 characters. Then enter the Group Key

Renewal period, which instructs the Router how often it should change the encryption keys.

WPA RADIUS

. This option features WPA used in coordination with a RADIUS server. (This should only be used

when a RADIUS server is connected to the Router.) First Select

TKIP

from the

WPA Algorithm

drop-down menu.

Enter the RADIUS server’s IP address and port number, along with the WPA Shared Key, which is the key shared

between the Router and the server. Last, enter the Group Key Renewal period, which instructs the Router how

often it should change the encryption keys.

WEP

. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a level of WEP

encryption,

64 bits 10 hex digits

or

128 bits 26 hex digits

. If you want to use a Passphrase, then enter it in the

Passphrase for keys

field and click the

Generate

button. If you want to enter the WEP key manually, then enter it

in the

WEP Key

field(s). To indicate which WEP key to use, select the appropriate

Default Key

number.
