The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain

name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other

server behind the Router. Before you can use this feature, you need to sign up for DDNS service with a DDNS

service provider, www.dyndns.org or www.TZO.com.

A MAC address is a 12-digit code assigned to a unique piece of hardware for identification. Some ISPs will

require you to register a MAC address in order to access the Internet.

If you do not wish to re-register the MAC

address with your ISP, you may assign the MAC address you have currently registered with your ISP to the Router

with the MAC Address Clone feature.

Enable/Disable

. To have the MAC Address cloned, click the radio button beside

Wireless-G Broadband Router with RangeBooster

The Setup Tab - Advanced Routing

This tab is used to set up the Router’s advanced functions. Operating Mode allows you to select the type(s) of

advanced functions you use. Dynamic Routing will automatically adjust how packets travel on your network. Static

Routing sets up a fixed route to another network destination.

NAT

If this Router is hosting your network’s connection to the Internet, select

Enable

. If another Router exists on

your network, select

Disable

. When Router is chosen,

Dynamic Routing

will be enabled.

Dynamic Routing (RIP)

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. When setting this

up, remember that the settings on the receiving and transmitting side

must

be the same.

Static Routing

. To set up a static route between the Router and another network, select a number from the

Route

Entries

drop-down list. (A static route is a pre-determined pathway that network information must travel to reach a

specific host or network.) Enter the information described below to set up a new static route. (Click the

Delete This

Entry

button to delete a static route.)

Enter Route Name

. Enter a name for the Route here, using a maximum of 25 alphanumeric characters.

Destination LAN IP

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

assign a static route.

Subnet Mask

. The Subnet Mask determines which portion of a Destination LAN 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.

Interface

. This interface tells you whether the Destination IP Address is on the

LAN & Wireless

(Ethernet and

wireless networks), the

Internet

(WAN), or

Loopback

(a dummy network in which one PC acts like a network—

necessary for certain software programs).

The Wireless Tab - Basic Wireless Settings

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

Wireless

. Select

Enabled

to enable wireless capabilities or

Disabled

to disable 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

Wireless 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 devices 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 devices in your

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

linksys

) to a unique name.

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.

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

The Wireless Tab - Wireless Security

Wireless-G Broadband Router with RangeBooster

The Wireless Tab - Wireless Security

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

mode options supported by the Router: WEP, WPA Personal, PSK2, PSK2-Mixed, WPA-Enterprise, PSK2 + RADIUS,

and RADIUS. (WEP stands for Wired Equivalent Privacy, and WPA stands for Wi-Fi Protected Access. WPA is a

stronger security method than WEP. PSK2 stands for Pre-shared Key 2, and is stronger than WPA-Personal.

RADIUS stands for Remote Authentication Dial-In User Service.) These seven are briefly discussed here.

WEP

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

WEP encryption,

40/64 bits (10 hex digits)

104/128 bits (26 hex digits)

. Then either generate a WEP key

using the Passphrase or enter the WEP key manually and select a TX (Transmit) Key (choose which Key to use).

WPA-Personal

. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the

type of encryption,

TKIP

AES

. Enter a passphrase (pre-shared key) of 8-63 characters. Then enter a Key

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

Figure 5-21: Wireless Tab - Wireless Security (WPA-

Personal)

IMPORTANT:

If you are using WPA Personal,

always remember that each device in your

wireless network MUST use the same WPA

Personal method and passphrase, or else the

network will not function properly.

IMPORTANT:

If you are using WEP

encryption, always remember that each

device in your wireless network MUST use

the same WEP encryption method and

encryption key, or else your wireless network

will not function properly.
