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. 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 off your modem, disconnect
the USB cable and connect an Ethernet cable to the WAN 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 Ethernet 300 from your computer or you will not be able to connect to the Internet.

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 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.

11D-Link DIR-300 User Manual
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. 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 WAN 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. 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 30 seconds for the router to boot.
7. Turn on your computer.
8. Verify the link lights on the router. The power light, WAN light, and the LAN light (the port that your computer is plugged
into) should be lit. If not, make sure your computer, modem, and router are powered on and verify the cable connections are
correct.
9. Skip to page 14 to congure your router.

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. 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 OK to continue.
