from the Internet. Support for WPA standards ensure that you’ll be able to use the best possible encryption method, regardless of your client devices.
In addition, this Xtreme N™ Router utilizes dual active rewalls (SPI and NAT) to prevent potential attacks from across the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11g and 802.11n specications. Actual data throughput will vary. Network conditions and environmental factors,
including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will adversely
aect wireless signal range.

Section 1 - Product Overview
• FasterWirelessNetworking - The DIR-651 provides up to 300Mbps* wireless connection with other 802.11n wireless clients. This
capability allows users to participate in real-time activities online, such as video streaming, online gaming, and real-time audio. The
performance of this 802.11n wireless router gives you the freedom of wireless networking at speeds 650% faster than 802.11g.
• Compatiblewith802.11gDevices - The DIR-651 is still fully compatible with the IEEE 802.11g standard, so it can connect with
existing 802.11g PCI, USB and Cardbus adapters.
• AdvancedFirewallFeatures - The Web-based user interface displays a number of advanced network management features
including:
• Content Filtering - Easily applied content ltering based on MAC Address, URL, and/or Domain Name.
• Filter Scheduling - These lters can be scheduled to be active on certain days or for a duration of hours or
Features
minutes.
• Secure Multiple/Concurrent Sessions - The DIR-651 can pass through VPN sessions. It supports multiple and
concurrent IPSec and PPTP sessions, so users behind the DIR-651 can securely access corporate networks.
• User-friendlySetupWizard - Through its easy-to-use Web-based user interface, the DIR-651 lets you control what information
is accessible to those on the wireless network, whether from the Internet or from your company’s server. Congure your router to
your specic settings within minutes.

Section 2 - Installation
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in the attic or garage.
Before you Begin
Please congure the router with the computer that was last connected directly to your modem. Also, you can only use the Ethernet port on your
modem. If you were using the USB connection before using the router, then you must turn o your modem, disconnect the USB cable and connect
an Ethernet cable to the Internet port on the router, and then turn the modem back on. In some cases, you may need to call your ISP to change
connection types (USB to Ethernet).
If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as WinPoet, Broadjump, or Enternet 300
from your computer or you will not be able to connect to the Internet.

Section 2 - Installation
Wireless Installation Considerations
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the operating range of your
wireless network. Keep in mind that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass
through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or
business. The key to maximizing wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or ceiling
can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is
minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be
almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will
travel straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building Materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range. Try to position
access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects
such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and concrete will degrade your
wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your
wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far away from your
wireless devices as possible. The base transmits a signal even if the phone in not in use.

Revoke:
Check this box to enable the reservation.
Enter the computer name or select from the drop-down menu
and click <<.
Enter the IP address you want to assign to the computer or
device. This IP Address must be within the DHCP IP Address
Range.
Enter the MAC address of the computer or device.
If you want to assign an IP address to the computer you are
currently on, click this button to populate the elds.
Click Save to save your entry. You must click Save Settings at
the top to activate your reservations.
In this section you can see what LAN devices are currently
leasing IP addresses.
Click Revoke to cancel the lease for a specic LAN device and
free an entry in the lease table. Do this only if the device no
longer needs the leased IP address, because, for example, it
has been removed from the network.
Reserve:
Note: The Revoke option will not disconnect a PC with a current network session from the network; you would need to use MAC Address Filter to do that. Revoke will
only free up a DHCP Address for the very next requester. If the previous owner is still available, those two devices may both receive an IP Address Conict error, or the
second device may still not receive an IP Address; in that case, you may still need to extend the “DHCP IP Address Range” to address the issue, it is located in the DHCP
Server section.
The Reserve option converts this dynamic IP allocation into a DHCP Reservation and adds the corresponding entry to the DHCP Reservations List.

Virtual Server
The DIR-651 can be congured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically
redirected to local servers in the LAN (Local Area Network).
The DIR-651 rewall feature lters out unrecognized packets to protect your LAN network so all computers networked with the DIR-651 are invisible
to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server. Depending on
the requested service, the DIR-651 redirects the external service request to the appropriate server within the LAN network.
The DIR-651 is also capable of port-redirection meaning incoming trac to a particular port may be redirected to a dierent port on the server
computer.
Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are pre-dened virtual services already
in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service.

have diculties working through NAT (Network Address Translation). Special Applications makes some of these applications work with the DIR-651.
If you need to run applications that require multiple connections, specify the port normally associated with an application in the “Trigger Port” eld,
select the protocol type as TCP or UDP, then enter the rewall (public) ports associated with the trigger port to open them for inbound trac.
The DIR-651 provides some predened applications in the table on the bottom of the web page. Select the application you want to use and enable
