Section 1 - Product Overview
• Faster Wireless Networking - The DIR-604 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.
• Compatible with 802.11g Devices - The DIR-604 is still fully compatible with the IEEE 802.11g standard,
so it can connect with existing 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 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 minutes.
Features
• Secure Multiple/Concurrent Sessions - The DIR-604 can pass through VPN sessions. It
supports multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-604
can securely access corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DIR-604 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.
* Maximum wireless signal rate derived from IEEE Standard 802.11g and Final 802.11n specications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network trafc, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
conditions will adversely affect wireless signal range.

Hardware Overview
Switching Among AP, Client, and Router Mode
The DIR-604 features a hardware switch located on the bottom of the device that enables users to switch among Router
mode, Client mode, and AP mode.
When the DIR-604 is operating in AP mode, the device acts as a basic access point without any routing functionality.
When the DIR-604 is operating in Client mode, the PC that is connected to the device will use it as a wireless network
interface in order that it can connect to a wireless router or access point.
When the DIR-604 is operating in Router mode, WAN connectivity is achieved via the DIR-604’s Ethernet port. In this
mode LAN clients need to access the DIR-604 via the DIR-604’s wireless connection.

Installation Considerations
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. 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 (0.5 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 difference. A solid metal door or aluminum studs may have a negative effect 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.

Connect to Cable/DSL/Satellite Modem
If your Internet connection is provided using a cable/DSL/satellite modem, carry out the following procedure before
connecting the router to a cable/DSL/satellite modem:
• Move the AP Mode/Client Mode/Router Mode switch on the DIR-604 so that it is in the Client Mode
position.
• Congure the wireless settings on the DIR-604 in Client Mode (see “Wireless Connection” on page 17 for
more information).
• After conguring the wireless settings, move the AP Mode/Client Mode/Router Mode switch so that it
is in the Router Mode position.
To connect 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. Turn the power off on your modem. If there is no on/off switch, then 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
Ethernet port on the Router.
5. Turn on or 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. Wait about 50 seconds for the router
to boot.
7. Turn on your computer.
8. Use the wireless connection on your computer to connect to the Router, using the wireless settings you congured

Connect to Another Router
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:
• Move the AP Mode/Client Mode/Router Mode switch on the DIR-604 so that it is in the AP Mode position.
• Disable UPnP
• Disable DHCP
• Change the LAN IP address to an available address on your network. The Ethernet port 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. Connect one of your computers to the Ethernet 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 Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings
to continue.
4. Click Setup and then click Network Settings. Uncheck the Enable DHCP Server server checkbox. Click Save Settings to continue.
5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings to
