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 configure 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 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, 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 
(fish tanks), mirrors, file 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.

7D-Link DIR-330 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 
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.  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, Internet 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. Refer to page 10 to configure your router.
Connect to Cable/DSL/Satellite Modem

8D-Link DIR-330 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 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 
save your settings. Use this new IP address to access the configuration 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.

DHCP stands for Dynamic Host Control Protocol. The DIR-330 has a built-in DHCP server. The DHCP Server will 
automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be 
DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers 
on, they will automatically load the proper TCP/IP settings provided by the DIR-330. The DHCP Server will automatically 
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.

PPTP uses TCP port 1723 for its control connection and uses GRE (IP protocol 47) for the PPP data. PPTP supports 
data encryption by using MPPE.
L2TP  uses  UDP  to  transport  the  PPP  data. This  is  often  encapsulated  in  IPSec  for  encryption  instead  of  using 
MPPE.

The DIR-330 can be configured 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-330 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked 
with the DIR-330 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-330 redirects the external 
service request to the appropriate server within the LAN network. 
The DIR-330 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a 
different 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-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to 
use that particular virtual service.
