D-LINK SYSTEMS, INC | WIRELESS ROUTER | SUPPORT

# SUPPORT MENU

Setup Internet There are two ways that you can configure your new D-Link router. You can either use the Setup Wizard or configure the settings manually.
Setup Wizard The Setup Wizard section contains two useful wizards to help setup the DIR-451 to quickly connect to your ISP (Internet Service Provider), and also to configure its Wireless settings.
Launch Internet Connection Setup Wizard Click this button to have the router walk you through a few simple steps to help you connect your router to the Internet.
Launch Wireless Security Setup Wizard Click this button to have the router walk you through configuring the settings of your wireless network, including security.
Manual Configure Chose this option if you would like to input the settings needed to connect your router to the Internet manually.
WWAN The WWAN Settings are used to connect the DIR-451 to the Internet. Any information that needs to be entered on this page will be provided to you by your ISP. Please select your ISP and the model of 3G card you are using from the ISP - Card dropdown menu, and enter your Username Password, and Service Name if needed. If you are unsure of which option to select or what information to enter in the fields provided, please contact your ISP.
Wireless Settings The Wireless Settings page contains the settings for the (Access Point) Portion of the DIR-451. This page allows you to customize your wireless network or configure the DIR-451 to fit an existing wireless network that you may already have setup.
Wireless Network Name Also known as the SSID (Service Set Identifier), this is the name of your Wireless Local Area Network (WLAN). By default the SSID of the DIR-451 is "dlink". This can be easily changed to establish a new wireless network or to add the DIR-451 to an existing wireless network.

Wireless Channel
Indicates which channel the DIR-451 is operating on. By default the channel is set to 6. This can be changed to fit the channel setting for an existing wireless network or to customize your new wireless network. Click the Enable Auto Scan checkbox to have the DIR-451 automatically select the channel that it will operate on. This option is recommended because the router will choose the channel with the least amount of interference.

802.11g Only Mode Enable this mode if your network is made up of purely 802.11g devices. If you have both 802.11b and 802.11g wireless clients, disable this mode.
Visibility Status Select Disabled if you would not like the SSID of your wireless network to be broadcasted by the DIR-451. If this option is Disabled, the SSID of the DIR-451 will not be seen by Site Survey utilities, so when setting up your wireless clients, you will have to know the SSID of your DIR-451 and enter it manually in order to connect to the router. This option is enabled by default.
Wireless Security Mode Securing your wireless network is important as it is used to protect the integrity of the information being transmitted over your wireless network. The DIR-451 is capable of 3 types of wireless security; WEP, WPA, and WPA2.

WEP
Wired Equivalent Protocol (WEP) is a wireless security protocol for Wireless Local Area Networks (WLAN). WEP provides security by encrypting the data that is sent over the WLAN. The DIR-451 supports 2 levels of WEP Encryption: 64-bit and 128-bit. WEP is disabled by default. The WEP setting can be changed to fit an existing wireless network or to customize your wireless network.

Authentication - Authentication is a process by which the DIR-451 verifies the identity of a network device that is attempting to join the wireless network. There are two types authentication for this device when using WEP.
Open System - Select this option to allow all wireless devices to communicate with the DIR-451 before they are required to provide the encryption key needed to gain access to the network.
Shared Key - Select this option to require any wireless device attempting to communicate with the DIR-451to provide the encryption key needed to access the network before they are allowed to communicate with the DIR-451.
WEP Encryption - Select the level of WEP Encryption that you would like to use on your network. The two supported levels of WEP encryption are 64-bit and 128-bit.
Key Type - The Key Types that are supported by the DIR-451 are HEX (Hexadecimal) and ASCII (American Standard Code for Information Interchange.) The Key Type can be changed to fit an existing wireless network or to customize your wireless network.
Keys - Keys 1-4 allow you to easily change wireless encryption settings to maintain a secure network. Simply select the specific key to be used for encrypting wireless data on the network.

WPA
Wi-Fi Protected Access authorizes and authenticates users onto the wireless network. WPA uses stronger security than WEP and is based on a key that changes automatically at a regular interval.

Cipher Type - The DIR-451 support two different cipher types when WPA is used as the Security Type. These two options are TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard).
PSK/EAP - When PSK is selected, your wireless clients will need to provide a Passphrase for authentication. When EAP is selected, you will need to have a RADIUS server on your network which will handle the authentication of all your wireless clients.
Passphrase - This is what your wireless clients will need in order to communicate with your DIR-451, when PSK is selected. Enter 8-63 alphanumeric characters. Be sure to write this Passphrase down as you will need to enter it on any other wireless devices you are trying to add to your network.
802.1X - This means of WPA authentication is used in conjunction with a RADIUS server that must be present on your network. Enter the IP address, port, and Shared Secret that you RADIUS is configured for. You also have the option to enter information for a second RADIUS server in the even that there are two on your network which you are using to authenticate wireless clients.

WPA2
Wi-Fi Protected Access 2 authorizes and authenticates users onto the wireless network. WPA2 uses stronger security than WEP and is based on a key that changes automatically at a regular interval.

Cipher Type - The DIR-451 support two different cipher types when WPA is used as the Security Type. These two options are TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard).
PSK/EAP - When PSK is selected, your wireless clients will need to provide a Passphrase for authentication. When EAP is selected, you will need to have a RADIUS server on your network which will handle the authentication of all your wireless clients.
Passphrase - This is what your wireless clients will need in order to communicate with your DIR-451, when PSK is selected. Enter 8-63 alphanumeric characters. Be sure to write this Passphrase down as you will need to enter it on any other wireless devices you are trying to add to your network.
802.1X - Enter the IP address, port, and shared secret of your RADIUS server configuration. You also have the option to enter information for a second RADIUS server in your network which you use to authenticate wireless clients.

Network Settings
These are the settings of the LAN (Local Area Network) interface for the device. These settings may be referred to as "private settings". You may change the LAN IP address if needed. The LAN IP address is private to your internal network and cannot be seen on the Internet. The default IP address is 192.168.0.1 with a subnet mask of 255.255.255.0.
IP Address - IP address of the DIR-451, default is 192.168.0.1.
Subnet Mask - Subnet Mask of DIR-451, default is 255.255.255.0.
Local Domain Name (optional) - Enter in the local domain name for your network.
DNS Relay - When DNS Relay is enabled, DHCP clients of the router will be assigned the router's LAN IP address as their DNS server. All DNS requests that the router receives will be forwarded to your ISPs DNS servers. When DNS relay is disabled, all DHCP clients of the router will be assigned the ISP DNS server.

DHCP Server
DHCP stands for Dynamic Host Control Protocol. The DHCP server assigns IP addresses to devices on the network that request them. These devices must be set to "Obtain the IP address automatically". By default, the DHCP Server is enabled on the DIR-451. The DHCP address pool contains the range of the IP address that will automatically be assigned to the clients on the network.

Starting IP address - The starting IP address for the DHCP server's IP assignment.
Ending IP address - The ending IP address for the DHCP server's IP assignment.
Lease Time - The length of time in minutes for the IP lease.

Dynamic DHCP client computers connected to the unit will have their information displayed in the Dynamic DHCP Client Table. The table will show the Host Name, IP Address, MAC Address, and Expired Time of the DHCP lease for each client computer.

DHCP Reservation
DHCP Reservations allow the router to assign the same IP address to a specific device on your network. The specified device will get the same DHCP IP address information every time it is turned on or requests an IP address. No other computer on your network will receive the specified static DHCP address. DHCP Reservations are very helpful when used for server computers on your network that are hosting applications such as Web and FTP.

Select Enabled to configure a DHCP Reservation. If you wish to disable this DHCP Reservation at a later date, click the edit icon next to the entry in the DHCP Reservation List, select the Disabled radio button, and then click Apply.
Computer Name - The Hostname of the network device you are configuring DHCP Reservation for.
IP Address - Enter the last octet of the IP address that you are configuring the network device to always obtain.
MAC Address - Enter the MAC address of the network device you are configuring a DHCP Reservation for.
Computer Name - If the network device you are would like to configure a DHCP Reservation for has already obtained an IP address from the router, you can select that computer from the drop down menu, click the arrow button, and the Name, MAC Address, and IP fields will be automatically populated with the network device's information, including the IP address it has already been assigned by the router.
Client computers with DHCP Reservations will have their information displayed in the DHCP Reservations List. The table will show the Host Name, IP Address, MAC Address, and Expired Time of the DHCP lease for each client computer.
