3. Password

Type in your password and retype it into the “Retype Password”

box to confirm it.

4. User Decide Login Server Manually

If your login server IP address is not available in the “Select Your

State” drop-down menu (1), you may manually enter the login

server IP address by placing a check in the box next to “User

decide login server manually” and type in the address next to

“Login Server” (5).

Setting Custom Domain Name Server (DNS) Settings

A “Domain Name Server” is a server located on the Internet that

translates Universal Resource Locater (URLs) like “www.belkin.com”

to IP addresses. Many Internet Service Providers (ISPs) do not require

you to enter this information into the Router. The “Automatic from ISP”

box (1) should be checked if your ISP did not give you a specific DNS

address. If you are using a static IP connection type, then you may

need to enter a specific DNS address and secondary DNS address for

your connection to work properly. If your connection type is dynamic

or PPPoE, it is likely that you do not have to enter a DNS address.

Leave the “Automatic from ISP” box checked. To enter the DNS address

settings, uncheck the “Automatic from ISP” box and enter your DNS

entries in the spaces provided. Click “Apply Changes” (2) to save

the settings.

Configuring your WAN Media Access Controller

(MAC) Address

All network components including cards, adapters, and routers, have

a unique “serial number” called a MAC address. Your Internet Service

Provider may record the MAC address of your computer’s adapter and

only let that particular computer connect to the Internet service. When

you install the Router, its own MAC address will be “seen” by the

ISP and may cause the connection not to work. Belkin has provided

the ability to clone (copy) the MAC address of the computer into the

Router. This MAC address, in turn, will be seen by the ISP’s system as

the original MAC address and will allow the connection to work. If you

are not sure whether your ISP needs to see the original MAC address,

simply clone the MAC address of the computer that was originally

connected to the modem. Cloning the address will not cause any

problems with your network.

Alternate Setup Method

section

Cloning your MAC Address

To clone your MAC address, make sure that you are using the computer

that was ORIGINALLY CONNECTED to your modem before the Router

was installed. Click the “Clone” button (1). Click “Apply Changes” (3).

Your MAC address is now cloned to the Router.

Entering a Specific MAC Address

In certain circumstances you may need a specific WAN MAC address.

You can manually enter one in the “MAC Address” page. Type in a

MAC address in the spaces provided (2) and click “Apply Changes” (3)

to save the changes. The Router’s WAN MAC address will now be

changed to the MAC address you specified.

Using the Web-Based Advanced User Interface

section

Using your Internet browser, you can access the Router’s Web-Based

Advanced User Interface. In your browser, type “192.168.2.1” (do

not type in anything else such as “http://” or “www”) then press the

“Enter” key.

You will see the Router’s home page in your browser window.

Viewing the LAN Settings

Clicking on the header of the LAN tab (1) will take you to the LAN

tab’s header page. A quick description of the functions can be

found here. To view the settings or make changes to any of the LAN

settings, click on “LAN Settings” (2) or to view the list of connected

computers, click on “DHCP Client List” (3).

Using the Web-Based Advanced User Interface

section

Changing LAN Settings

All settings for the internal LAN setup of the Router can be viewed

and changed here.

1. IP Address

The “IP address” is the internal IP address of the Router. The

default IP address is “192.168.2.1”. To access the advanced

setup interface, type this IP address into the address bar of your

browser. This address can be changed if needed. To change the

IP address, type in the new IP address and click “Apply Changes”.

The IP address you choose should be a non-routable IP.

Examples of a non-routable IP are:

192.168.x.x (where x is anything between 0 and 255)

10.x.x.x (where x is anything between 0 and 255)

2. Subnet Mask

There is no need to change the subnet mask. This is a unique,

advanced feature of your Belkin Router. It is possible to change

the subnet mask if necessary, however, do NOT make changes to

the subnet mask unless you have a specific reason to do so. The

default setting is “255.255.255.0”.

3. DHCP Server

The DHCP server function makes setting up a network very easy

by assigning IP addresses to each computer on the network

automatically. The default setting is “On”. The DHCP server

can be turned OFF if necessary, however, in order to do so you

must manually set a static IP address for each computer on

your network. To turn off the DHCP server, select “Off” and click

“Apply Changes”.

4. IP Pool

The range of IP addresses set aside for dynamic assignment to the

computers on your network. The default is 2–100 (99 computers). If

you want to change this number, you can do so by entering a new

starting and ending IP address and clicking on “Apply Changes”.

The DHCP server can assign 100 IP addresses automatically. This

means that you cannot specify an IP address pool larger than 100

computers. For example, starting at 50 means you have to end at

150 or lower so as not to exceed the 100-client limit. The starting

IP address must be lower in number than the ending IP address.

5. Lease Time

The length of time the DHCP server will reserve the IP address

for each computer. We recommend that you leave the lease

time set to “Forever”. The default setting is “Forever”, meaning

that any time a computer is assigned an IP address by the

DHCP server, the IP address will not change for that particular

computer. Setting lease times for shorter intervals such as one

day or one hour frees IP addresses after the specified period of

time. This also means that a particular computer’s IP address

may change over time. If you have set any of the other advanced

features of the Router such as DMZ or client IP filters, these are

dependent on the IP address. For this reason, you will not want

the IP address to change.

6. Local Domain Name

The default setting is “Belkin”. You can set a local domain name

(network name) for your network. There is no need to change this

setting unless you have a specific advanced need to do so. You can

name the network anything you want such as “MY NETWORK”.

Using the Web-Based Advanced User Interface

section

Viewing the DHCP Client List Page

You can view a list of the computers (known as clients), which are

connected to your network. You are able to view the IP address (1) of

the computer, the host name (2) (if the computer has been assigned

one), and the MAC address (3) of the computer’s network interface

card (NIC). Pressing the “Refresh” button will update the list. If there

have been any changes, the list will be updated.

section

Configuring the Wireless Network Settings

The Wireless tab lets you make changes to the wireless network

settings. From this tab you can make changes to the wireless network

name (SSID), operating channel, encryption security settings, and

configure the Router to be used as an access point.

Changing the Wireless Network Name (SSID)

To identify your wireless network, a name called the SSID (Service

Set Identifier) is used. The default SSID of the Router is “belkin54g”.

You can change this to anything you want to or you can leave it

unchanged. If there are other wireless networks operating in your

area, you will want to make sure that your SSID is unique (does not

match that of another wireless network in the area). To change the

SSID, type in the SSID that you want to use in the SSID field (1) and

click “Apply Changes” (2). The change is immediate. If you make a

change to the SSID, your wireless-equipped computers may also need

to be reconfigured to connect to your new network name. Refer to the

documentation of your wireless network adapter for information on

making this change.

Using the Web-Based Advanced User Interface

section

Using the Wireless Mode Switch

Your Router can operate in three different wireless modes: “802.11g-

Auto”, “802.11g-Only”, and “802.11g-LRS”. The different modes are

explained below.

802.11g-Auto Mode

In this mode, the Router is compatible with 802.11b and 802.11g

wireless clients simultaneously. This is the factory default mode and

ensures successful operation with all Wi-Fi-compatible devices. If

you have a mix of 802.11b and 802.11g clients in your network, we

recommend setting the Router to 802.11g-Auto mode. This setting

should only be changed if you have a specific reason to do so.

802.11g-Only Mode

802.11g-Only mode works with 802.11g clients only. This mode

is recommended only if you want to prevent 802.11b clients from

accessing your network. To switch modes, select the desired

mode from the “Wireless Mode” drop-down box. Then, click

“Apply Changes”.

802.11g-LRS Mode

We recommend you DO NOT use this mode unless you have a very

specific reason to do so. This mode exists only to solve unique

problems that may occur with some 802.11b client adapters and is

NOT necessary for interoperability of 802.11g and 802.11b standards.

When to Use 802.11g-LRS Mode

In some cases, older 802.11b clients may not be compatible with

802.11g wireless. These adapters tend to be of inferior design and

may use older drivers or technology. 802.11g-LRS (Limited Rate

Support) allows these clients to be compatible with the newer

802.11g technology. Switching to this mode can solve problems that

sometimes occur with these clients. If you suspect that you are using

a client adapter that falls into this category of adapters, first check

with the adapter vendor to see if there is a driver update. If there

is no driver update available, switching to 802.11g-LRS mode may

fix your problem. Please note that switching to 802.11g-LRS mode may

decrease 802.11g performance slightly.

Using the Web-Based Advanced User Interface

section

Using High-Speed Mode

The Router supports two High-Speed modes, 125HSM* mode and

Frame Bursting mode.

Selecting “125HSM mode” will result in all devices running in 125HSM

mode if all devices are capable of 125Mbps speeds. If any

non-125HSM device connects or associates with the network, the

Router will automatically shift the entire network back to Frame

Bursting mode.

Selecting “Frame Bursting” will result in all devices capable of

Frame Bursting to function in Frame Bursting mode, and all clients

not capable, to operate in normal 802.11g modes. Frame Bursting

mode supports both Frame Bursting-enabled devices and non-Frame

Bursting-enabled devices simultaneously. Frame Bursting mode is

based on the unreleased 802.11e specification.

Selecting “Off” will disable Turbo mode.

*When operating in High-Speed Mode, this Wi-Fi device may achieve an actual throughput

of up to or greater than 34.1Mbps, which is the equivalent throughput of a system following

802.11g protocol and operating at a signaling rate of 125Mbps. Actual throughput will vary

depending on environmental operational and other factors.

Using the Web-Based Advanced User Interface

section

Changing the Wireless Channel

There are a number of operating channels you can choose from. In

the United States and Australia, there are 11 channels. In the United

Kingdom and most of Europe, there are 13 channels. In a small

number of other countries, there are other channel requirements.

Your Router is configured to operate on the proper channels for

the country you reside in. The default channel is 11 (unless you are

in a country that does not allow channel 11). The channel can be

changed if needed. If there are other wireless networks operating in

your area, your network should be set to operate on a channel that is

different than the other wireless networks. For best performance, use

a channel that is at least five channels away from the other wireless

network. For instance, if another network is operating on channel 11,

then set your network to channel 6 or below. To change the channel,

select the channel from the drop-down list. Click “Apply Changes”.

The change is immediate.

Using the Web-Based Advanced User Interface

section

Using the Broadcast SSID Feature

Note: This advanced feature should be employed by advanced users only.

For security, you can choose not to broadcast your network’s SSID.

Doing so will keep your network name hidden from computers that

are scanning for the presence of wireless networks. To turn off the

broadcast of the SSID, remove the check mark from the box next to

“Broadcast SSID”, and then click “Apply Changes”. The change is

immediate. Each computer now needs to be set to connect to your

specific SSID; an SSID of “ANY” will no longer be accepted. Refer to

the documentation of your wireless network adapter for information

on making this change.

Protected Mode Switch

As part of the 802.11g specification, Protected Mode ensures proper

operation of 802.11g clients and access points when there is heavy

802.11b traffic in the operating environment. When Protected mode

is ON, 802.11g scans for other wireless network traffic before it

transmits data. Therefore, using this mode in environments with

HEAVY 802.11b traffic or interference achieves best performance

results. If you are in an environment with very little—or no—other

wireless network traffic, your best performance will be achieved with

Protected mode OFF.

Securing your Wi-Fi® Network

Here are a few different ways you can maximize the security of

your wireless network and protect your data from prying eyes and

ears. This section is intended for the home, home office, and small

office user. At the time of this manual’s publication, there are three

encryption methods available.

WEP (Wired Equivalent Privacy)

WEP (Wired Equivalent Privacy) is a common protocol that adds

security to all Wi-Fi-compliant wireless products. WEP was designed

to give wireless networks the equivalent level of privacy protection as

a comparable wired network.

64-Bit WEP

64-bit WEP was first introduced with 64-bit encryption, which

includes a key length of 40 bits plus 24 additional bits of

system-generated data (64 bits total). Some hardware

manufacturers refer to 64-bit as 40-bit encryption. Shortly after

the technology was introduced, researchers found that 64-bit

encryption was too easy

to decode.

Using the Web-Based Advanced User Interface

section

128-Bit WEP

As a result of 64-bit WEP’s potential security weaknesses, a more

secure method of 128-bit encryption was developed. 128-bit

encryption includes a key length of 104 bits plus 24 additional

bits of system-generated data (128 bits total). Some hardware

manufacturers refer to 128-bit as 104-bit encryption.

Most of the new wireless equipment in the market today supports

both 64-bit and 128-bit WEP encryption, but you might have

older equipment that only supports 64-bit WEP. All Belkin

wireless products will support both 64-bit and 128-bit WEP.

Encryption Keys

After selecting either the 64-bit or 128-bit WEP encryption mode, it is

critical that you generate an encryption key. If the encryption key is

not consistent throughout the entire wireless network, your wireless

networking devices will be unable to communicate with one another

on your network and you will not be able to successfully communicate

within your network.

You can enter your key by typing in the hex key manually, or you can

type in a passphrase in the “Passphrase” field and click “Generate”

to create a key. A hex (hexadecimal) key is a mixture of numbers and

letters from A–F and 0–9. For 64-bit WEP, you need to enter 10 hex

keys. For 128-bit WEP, you need to enter 26 hex keys.

For instance:

AF 0F 4B C3 D4 = 64-bit WEP key

C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key

The WEP passphrase is NOT the same as a WEP key. Your card uses

this passphrase to generate your WEP keys, but different hardware

manufacturers might have different methods on generating the keys.

If you have multiple vendors’ equipments in your network, the easiest

thing to do is to use the hex WEP key from your Router or access

point and enter it manually into the hex WEP key table in your card’s

configuration screen.

Using the Web-Based Advanced User Interface

section

WPA (Wi-Fi Protected Access)

WPA (Wi-Fi Protected Access) is a new Wi-Fi standard that was

designed to improve upon the security features of WEP. To use WPA

security, the drivers and software of your wireless equipment must

be upgraded to support WPA. These updates will be found on the

wireless vendors website. There are two types of WPA security, WPA-

PSK (no server) and WPA (with radius server).

WPA-PSK (no server) uses what is known as a

Pre-Shared key as the Network key. A Network key is basically a

password that is between 8 and 63 characters long. It can be a

combination of letters, numbers, or characters. Each client uses

the same Network key to access the network. Typically, this is the

mode that will be used in a home environment.

WPA (with radius server) is a system where a radius server

distributes the Network key to the clients automatically. This is

typically found in a business environment.

For a list of Belkin wireless products that support WPA, please visit

our website at www.belkin.com/networking.

Using the Web-Based Advanced User Interface

section

Sharing the Same Network Keys

Most Wi-Fi products ship with security turned off. So once you have

your network working, you need to activate WEP or WPA and make

sure your wireless networking devices are sharing the same

Network key.

The Wireless G Desktop Network Card cannot access the network

because it is using a different Network key than the Network key that

is configured on the Wireless G Router.

Using a Hexadecimal Key

A hexadecimal key is a mixture of numbers and letters from A–F and

0–9. 64-bit keys are five two-digit numbers. 128-bit keys are 13

two-digit numbers.

For instance:

AF 0F 4B C3 D4 = 64-bit key

C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit key

In the boxes below, make up your key by writing in two characters

between A–F and 0–9 in each box. You will use this key to program

the encryption settings on your Router and your wireless computers.

Note to Mac users: Original Apple AirPort® products support 64-

bit encryption only. Apple AirPort 2 products can support 64-bit or

128-bit encryption. Please check your product to see which version

you are using. If you cannot configure your network with 128-bit

encryption, try 64-bit encryption.

Changing the Wireless Security Settings

Your Router is equipped with WPA (Wireless Protected Access), the

latest wireless security standard. It also supports the legacy security

standard, WEP (Wired Equivalent Privacy). By default, wireless

security is disabled. To enable security, you must first determine

which standard you want to use. To access the security settings, click

“Security” on the Wireless tab.

WPA Setup

Note: To use WPA security, all your clients must be upgraded to

drivers and software that support it. At the time of this manual’s

publication, a security patch download is available, for free, from

Microsoft. This patch works only with the Windows XP operating

system. You also need to download the latest driver for your Belkin

Wireless G Desktop or Notebook Network Card from the Belkin

support site. Other operating systems are not supported at this time.

Microsoft’s patch only supports devices with WPA-enabled drivers

such as Belkin 802.11g products.

There are two types of WPA security: WPA-PSK (no server) and WPA

(with radius server). WPA-PSK (no server) uses a so-called Pre-

Shared key as the security key. A Pre-Shared key is a password that

is between 8 and 63 characters long. It can be a combination of

letters, numbers, and other characters. Each client uses the same key

to access the network. Typically, this mode will be used in a home

environment.

WPA (with radius server) is a configuration wherein a radius server

distributes the keys to the clients automatically. This is typically used

in a business environment.

Setting WPA-PSK (no server)

1. From the “Security Mode” drop-down menu, select “WPA-PSK

(no server)”.

2. For Encryption Technique, select “TKIP” or “AES”. This setting

will have to be identical on the clients that you set up.

3. Enter your pre-shared key. This can be from 8 to 63 characters

and can be letters, numbers, or symbols. This same key must be

used on all of the clients that you set up. For example, your PSK

might be something like: “Smith family network key”.
