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 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 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 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, 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 congure your router. 
Connect to Cable/DSL/Satellite Modem

12D-Link DIR-300 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. 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.

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.

Select  the  basic  transfer  rates  based  on  the  speed  of 
wireless adapters on your wireless network. It is strongly 
recommended to keep this setting to Auto.
Set the transmit power of the antennas.
Beacons are packets sent by an Access Point to synchronize 
a wireless network. Specify a value. 100 is the default setting 
and is recommended. 
This value should remain at its default setting of 2432. If 
inconsistent data ow is a problem, only a minor modication 
should be made.
The fragmentation threshold, which is specied in bytes, determines whether packets will be fragmented. Packets exceeding 
the 2346 byte setting will be fragmented before transmission. 2346 is the default setting. 
(Delivery Trafc Indication Message) 3 is the default setting. A DTIM is a countdown informing clients of the next window for 
listening to broadcast and multicast messages.
Select Short or Long Preamble. The Preamble denes the length of the CRC block (Cyclic Redundancy Check is a common 
technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless 
network adapters. Auto is the default setting. Note: High network trafc areas should use the shorter preamble type.
CTS (Clear To Send) is a function used to minimize collisions among wireless devices on a wireless local area network 
(LAN). CTS will make sure the wireless network is clear before a wireless client attempts to send wireless data. Enabling 
CTS will add overhead and may lower wireless through put. None: CTS is typically used in a pure 802.11g environment. If 
CTS is set to “None” in a mixed mode environment populated by 802.11b clients, wireless collisions may occur frequently.  
Always: CTS will always be used to make sure the wireless LAN is clear before sending data. Auto: CTS will monitor the 
wireless network and automatically decide whether to implement CTS based on the amount of trafc and collisions that 
occurs on the wireless network.
WMM is QoS for your wireless network. Enable this option to improve the quality of video and voice applications for your 
wireless clients.
