Add/Edit DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the

network device with the specified MAC address any time it requests an IP address. This

is almost the same as when a device has a static IP address except that the device must

still request an IP address from the router. The router will provide the device the same IP

address every time. DHCP Reservations are helpful for server computers on the local

network that are hosting applications such as Web and FTP. Servers on your network

should either use a static IP address or use this option.

Computer Name

You can assign a name for each computer that is given a reserved IP address. This may

help you keep track of which computers are assigned this way. Example:

Game Server

.

IP Address:

The LAN address that you want to reserve.

MAC Address

To input the MAC address of your system, enter it in manually or connect to the router's

Web-Management interface from the system and click the

Copy Your PC's MAC

Address

button.

A MAC address is usually located on a sticker on the bottom of a network device. The

MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually

separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your

network device is a computer and the network card is already located inside the

computer, you can connect to the router from the computer and click the

Copy Your

PC's MAC Address

button to enter the MAC address.

As an alternative, you can locate a MAC address in a specific operating system by

following the steps below:

Windows 98

Windows Me

Go to the Start menu, select Run, type in

winipcfg

, and hit Enter. A

popup window will be displayed. Select the appropriate adapter from

the pull-down menu and you will see the Adapter Address. This is the

MAC address of the device.

Windows 2000

Windows XP

Go to your Start menu, select Programs, select Accessories, and

select Command Prompt. At the command prompt type

ipconfig /all

and hit Enter. The physical address displayed for the adapter

connecting to the router is the MAC address.

Mac OS X

Go to the Apple Menu, select System Preferences, select Network,

and select the Ethernet Adapter connecting to the router. Select the

Ethernet button and the Ethernet ID will be listed. This is the same as

the MAC address.

Enable

Specifies whether the entry will be active or inactive.

Save/Update

Record the changes you have made into the following list.

Clear

Re-initialize this area of the screen, discarding any changes you have made.

DHCP Reservations List

This shows clients that you have specified to have reserved DHCP addresses. Click the

Enable checkbox at the left to directly activate or de-activate the entry. An entry can be

changed by clicking the Edit icon or can be deleted by clicking the Delete icon. When you

click the Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is

activated for editing.

WIRELESS (WI-FI)

The wireless section is used to configure the wireless settings for your router. Note that changes

made in this section may also need to be duplicated on wireless clients that you want to connect

to your wireless network.

To protect your privacy, use the wireless security mode to configure the wireless security

features. This device supports three wireless security modes including: WEP, WPA-Personal, and

WPA-Enterprise. WEP is the original wireless encryption standard. WPA provides a higher level

of security. WPA-Personal does not require an authentication server. The WPA-Enterprise option

does require a RADIUS authentication server.

Add Wireless Device with WPS (Wi-Fi Protected Setup) Wizard

This Wizard helps you add wireless devices to the wireless network using the Wi-Fi

Protected Setup protocol.

The wizard will prompt you to enter the PIN for the device, or ask you to press the

configuration button on the device. If the device supports Wi-Fi Protected Setup and has

a configuration button, you can add it to the network by pressing the configuration button

on the device and then the on the router within 60 seconds. The status LED on the router

will flash three times if the device has been successfully added to the network.

There are several ways to add a wireless device to your network. Access to the wireless

network is controlled by a “registrar”. A registrar only allows devices onto the wireless

network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup button

on the device. The router acts as a registrar for the network, although other devices may

act as a registrar as well.

Enable Wireless

This option turns off and on the wireless connection feature of the router. When you set

this option, the following parameters are in effect.

Require User Login

This option turns off and on the user login feature of the router. When you enable this

option a wireless user must enter a password to gain access to the the internet. It will

also limit internet access to only 32 simultaneous clients.

Wireless Network Name

When you are browsing for available wireless networks, this is the name that will appear

in the list (unless Visibility Status is set to Invisible, see below). This name is also referred

to as the SSID. For security purposes, it is highly recommended to change from the pre-

configured network name.

Enable Auto Channel Scan

If you select this option, the router automatically finds the channel with least interference

and uses that channel for wireless networking. If you disable this option, the router uses

the channel that you specify with the following

Wireless Channel

option.

Wireless Channel

A wireless network uses specific channels in the wireless spectrum to handle

communication between clients. Some channels in your area may have interference from

other electronic devices. Choose the clearest channel to help optimize the performance

and coverage of your wireless network.

802.11 Mode

If all of the wireless devices you want to connect with this router can connect in the same

transmission mode, you can improve performance slightly by choosing the appropriate

"Only" mode. If you have some devices that use a different transmission mode, choose

the appropriate "Mixed" mode.

Channel Width

The "Auto 20/40 MHz" option is usually best. The other options are available for special

circumstances.

Transmission Rate

By default the fastest possible transmission rate will be selected. You have the option of

selecting the speed if necessary.

Visibility Status

The Invisible option allows you to hide your wireless network. When this option is set to

Visible, your wireless network name is broadcast to anyone within the range of your

signal. If you're not using encryption then they could connect to your network. When

Invisible mode is enabled, you must enter the Wireless Network Name (SSID) on the

client manually to connect to the network.

Security Mode

Unless one of these encryption modes is selected, wireless transmissions to and from

your wireless network can be easily intercepted and interpreted by unauthorized users.

WEP

A method of encrypting data for wireless communication intended to provide the same

level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain

access to a WEP network, you must know the key. The key is a string of characters that

you create. When using WEP, you must determine the level of encryption. The type of

encryption determines the key length. 128-bit encryption requires a longer key than 64-bit

encryption. Keys are defined by entering in a string in HEX (hexadecimal - using

characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange -

alphanumeric characters) format. ASCII format is provided so you can enter a string that

is easier to remember. The ASCII string is converted to HEX for use over the network.

Four keys can be defined so that you can change keys easily. A default key is selected

for use on the network.

Example:

64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid

string of 10 characters for 64-bit encryption.)

128-bit hexadecimal keys are exactly 26 characters in length.

(456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit

encryption.)

64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5

characters for 64-bit encryption.)

128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string

of 13 characters for 128-bit encryption.)

Note that, if you enter fewer characters in the WEP key than required, the remainder of

the key is automatically padded with zeros.

WPA-Personal and WPA-Enterprise

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security

standards published by the Wi-Fi Alliance. The

WPA Mode

further refines the variant that

the router should employ.

WPA Mode:

WPA is the older standard; select this option if the clients that will be used

with the router only support the older standard. WPA2 is the newer implementation of the

stronger IEEE 802.11i security standard. With the "WPA2" option, the router tries WPA2

first, but falls back to WPA if the client only supports WPA. With the "WPA2 Only" option,

the router associates only with clients that also support WPA2 security.

Cipher Type:

The encryption algorithm used to secure the data communication. TKIP

(Temporal Key Integrity Protocol) provides per-packet key generation and is based on

WEP. AES (Advanced Encryption Standard) is a very secure block based encryption.

With the "TKIP and AES" option, the router negotiates the cipher type with the client, and

uses AES when available.

Group Key Update Interval:

The amount of time before the group key used for

broadcast and multicast data is changed.

WPA-Personal

This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).

Pre-Shared Key:

The key is entered as a pass-phrase of up to 63 alphanumeric

characters in ASCII (American Standard Code for Information Interchange) format at both

ends of the wireless connection. It cannot be shorter than eight characters, although for

proper security it needs to be of ample length and should not be a commonly known

phrase. This phrase is used to generate session keys that are unique for each wireless

client.

Example:

Wireless Networking technology enables ubiquitous communication

WPA-Enterprise

This option works with a RADIUS Server to authenticate wireless clients. Wireless clients

should have established the necessary credentials before attempting to authenticate to

the Server through this Gateway. Furthermore, it may be necessary to configure the

RADIUS Server to allow this Gateway to authenticate users.

Authentication Timeout:

Amount of time before a client will be required to re-

authenticate.

RADIUS Server IP Address:

The IP address of the authentication server.

RADIUS Server Port:

The port number used to connect to the authentication server.

RADIUS Server Shared Secret:

A pass-phrase that must match with the authentication

server.

MAC Address Authentication:

If this is selected, the user must connect from the same

computer whenever logging into the wireless network.

Advanced:

Optional Backup RADIUS Server

This option enables configuration of an optional second RADIUS server. A second

RADIUS server can be used as backup for the primary RADIUS server. The second

RADIUS server is consulted only when the primary server is not available or not

responding. The fields

Second RADIUS Server IP Address

,

RADIUS Server Port

,

Second RADIUS server Shared Secret

,

Second MAC Address Authentication

provide the corresponding parameters for the second RADIUS Server.
