Section 1 - Product Overview
Features
• Faster Wireless Networking - The DIR-612 provides wireless connection of up to 300Mbps* for 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.
• Compatible with 802.11b and 802.11g Devices - The DIR-612 is fully compatible with the IEEE 802.11b and IEEE
802.11g standard, so it can connect with existing 802.11b and IEEE 802.11g PCI, USB and Cardbus adapters.
• Advanced Firewall Features - The Web-based user interface displays a number of advanced network management
features including:
• Content Filtering - Easily applied content ltering based on URL.
• Secure Multiple/Concurrent Sessions - The DIR-612 can pass through VPN sessions. It supports
multiple and concurrent PPTP sessions, so users behind the DIR-612 can securely access corporate
networks.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DIR-612 lets you control what
information is accessible to those on the wireless network, whether from the Internet or from your company’s
server. Congure your router to your specic settings within minutes.
* Maximum wireless signal rate derived from IEEE Standard 802.11g and Draft 802.11n specications. Actual data throughput will vary. Network conditions and environmental
factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will
adversely aect wireless signal range.

Section 2 - Installation
Before You Begin
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.
• Please congure the router with the computer that was last connected directly to your modem.
• 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.
• When running the Setup Wizard, make sure the computer is connected to the Internet and online or the wizard
will not work. If you have disconnected any hardware, re-connect your computer back to the modem and make
sure you are online.

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, however, 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 dierence. A solid metal door or aluminum studs may have a negative eect 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 2.4 GHz 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 2.4
GHz 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.

Section 2 - Installation
If you are connecting the router to a cable/DSL/satellite modem, please follow the steps below:
1. Place the router in an open and central location. Do not plug the power adapter into the router.
2. Unplug the modem’s power adapter. Shut down your computer.
3. Unplug the Ethernet cable (that connects your computer to your modem) from your computer and place it into
the Internet port on the router.
4. Plug an Ethernet cable into one of the four LAN ports on the router. Plug the other end into the Ethernet port
on your computer.
5. Plug in your modem. Wait for the modem to boot (about 30 seconds).
6. Plug the power adapter to the router and connect to an outlet or power strip.
7. Use the power switch to power on the router. Wait about 30 seconds for the router to boot.
8. Turn on your computer.
9. Refer to “Getting Started” on page 11 to congure your router.
Connect to Cable/DSL/Satellite Modem

9D-Link DIR-612 User Manual
Section 2 - Installation
If you are connecting the D-Link router to another router to use as a wireless access point and/or switch, you will have to do
the following before connecting the router to your network:
• Disable UPnP™
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot accept
a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router and use the power switch to power up the router. Connect one of your computers to the
router (LAN port) using an Ethernet cable. Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between
2 and 254). Please see the Networking Basics section for more information. If you need to change the settings, write down
your existing settings before making any changes. In most cases, your computer should be set to receive an IP address
automatically in which case you will not have to do anything to your computer.
2. Open a web browser and enter http://192.168.0.1 and press Enter. When the login window appears, set the user name to
Admin and leave the password box empty. Click Log In to continue.
3. Click on Advanced and then click UPnP. Uncheck the Enable checkbox. Click Apply Changes to continue.
4. Click Setup and then click Local Network. Under DHCP Server Settings, select None in the DHCP Mode pulldown menu.
Click Apply Changes to continue.
5. Remaining in Local Network, go to LAN Interface Setup and enter an available IP address and the subnet mask of your
network. Click Apply Changes to save your settings. Use this new IP address to access the conguration utility of the router
in the future. Close the browser and change your computer’s IP settings back to the original values as in Step 1.

6. Disconnect the Ethernet cable from the router and reconnect your computer to your network.
7. Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug anything
into the Internet (WAN) port of the D-Link router.
8. You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To congure your wireless
network, open a web browser and enter the IP address you assigned to the router. Refer to the Conguration and Wireless
Security sections for more information on setting up your wireless network.
