1.DHCP Server Settings

DHCP stands for Dynamic Host Control Protocol. The DIR-665 has a built-in DHCP server. The DHCP Server will automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers on, they will automatically load the proper TCP/IP settings provided by the DIR-665. The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and ending address of the IP address pool.


Enable DHCP Server:

Check this box to enable the DHCP server on your router. Uncheck to disable this function.

DHCP IP Address Range:

Enter the starting and ending IP addresses for the DHCP server’s IP assignment.

Note: If you statically (manually) assign IP addresses to your computers or devices, make sure the IP addresses are outside of this range or you may have an IP conflict.

DHCP Lease Time:

The length of time for the IP address lease. Enter the Lease time in minutes.

Always Broadcast:

Enable this feature to broadcast your networks DHCP server to LAN/WLAN clients.

NetBIOS Announcement:

NetBIOS allows LAN hosts to discover all other computers within the network, enable this feature to allow the DHCP Server to offer NetBIOS configuration settings.

Learn NetBIOS from WAN:

Enable this feature to allow WINS information to be learned from the WAN side, disable to allow manual configuration.

NetBIOS Scope:

This feature allows the configuration of a NetBIOS ‘domain’ name under which network hosts operates. This setting has no effect if the ‘Learn NetBIOS information from WAN’ is activated.

NetBIOS Mode Type:

Select the different type of NetBIOS node: Broadcast only, Point-to-Point, Mixed-mode, and Hybrid.

Primary/Secondary WINS IP Address:

Enter your Primary (and Secondary) WINS IP address(es).

2.DHCP Reservation

If you want a computer or device to always have the same IP address assigned, you can create a DHCP reservation. The router will assign the IP address only to that computer or device.

Note: This IP address must be within the DHCP IP Address Range.


Check this box to enable the reservation.

Computer Name:

Enter the computer name or select from the drop-down menu and click <<.

IP Address:

Enter the IP address you want to assign to the computer or device. This IP Address must be within the DHCP IP Address Range

MAC Address

Enter the MAC address of the computer or device.

Copy Your PC’s MAC Address:

If you want to assign an IP address to the computer you are currently on, click this button to populate the fields.


Click Save to save your entry. You must click Save Settings at the top to activate your reservations.

When entering the IP address of the D-Link router DIR-665( for example), you are not connecting to a website on the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.

1.Make sure you have an updated Java-enabled web browser. We recommend the following:

• Internet Explorer 6.0 or higher
• Netscape 8 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher

2.Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on.

3.Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included with your firewall software for more information on disabling or configuring it.

4.Configure your Internet settings:

• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.

5.Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This should open the login page for your the web management.

6.If you still cannot access the configuration, unplug the power to the D-Link router for 10 seconds and plug back in. Wait about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.
