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. 
•  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.
•  When running the Setup Wizard from the D-Link CD, make sure the computer you are running the CD 
from 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 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.

13D-Link DIR-628 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. Skip to page 15 to configure your router. 
Connect to Cable/DSL/Satellite Modem

14D-Link DIR-628 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.

The DIR-628 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-628 firewall feature filters out unrecognized packets to protect your LAN network so all computers networked 
with the DIR-628 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-628 redirects the external 
service request to the appropriate server within the LAN network. 
The DIR-628 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.

Traffic Shaping
This option is enabled by default when the Traffic 
Shaping option is enabled. This option will allow 
your router to automatically determine the uplink 
speed of your Internet connection.
This displays the detected uplink speed.
The speed at which data can be transferred from 
the router to your ISP. This is determined by your 
ISP.  ISP’s  often  speed  as  a  download/upload 
pair. For example, 1.5Mbits/284Kbits. Using this 
example, you would enter 284. Alternatively you 
can test your uplink speed with a service such 
as www.dslreports.com.
By default, the router automatically determines 
whether the underlying connection is an xDSL/
Frame-relay network or some other connection 
type (such as cable modem or Ethernet), and it 
displays the result as Detected xDSL or Frame 
Relay Network. If you have an unusual network 
connection in which you are actually connected 
via  xDSL  but  for  which  you  configure  either 
“Static” or “DHCP” in the Internet settings, setting this option to xDSL or Other Frame Relay Network ensures that the router 
will recognize that it needs to shape traffic slightly differently in order to give the best performance. Choosing xDSL or Other 
Frame Relay Network causes the measured uplink speed to be reported slightly lower than before on such connections, but 
gives much better results.

Firewall Settings
A firewall protects your network from the outside world. The D-Link DIR-628 offers a firewall type functionality. The SPI 
feature helps prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain 
types of applications. If you choose to expose a computer, you cam enable DMZ. DMZ is short for Demilitarized Zone. 
This option will expose the chosen computer completely to the outside world.
SPI  (Stateful  Packet  Inspection,  also  known  as  dynamic  packet 
filtering) helps to prevent cyber attacks by tracking more state per 
session.  It  validates  that  the  traffic  passing  through  the  session 
conforms to the protocol.
Select one of the following for TCP and UDP ports:
Endpoint Independent - Any incoming traffic sent to an open port 
will be forwarded to the application that opened the port. The port will 
close if idle for 5 minutes.
Address Restricted - Incoming traffic must match the IP address of 
the outgoing connection.
Address +  Port Restriction  -  Incoming  traffic  must  match  the  IP 
address and port of the outgoing connection.
Enable this  feature  to  protect  your  network  from  certain  kinds  of 
“spoofing” attacks. 
If an application has trouble working from behind the router, you can 
expose one computer to the Internet and run the application on that 
computer.
Note: Placing a computer in the DMZ may expose that computer to 
a variety of security risks. Use of this option is only recommended 
as a last resort.
Specify the IP address of the computer on the LAN that you want to have unrestricted Internet communication. If this computer 
obtains it’s IP address automatically using DHCP, be sure to make a static reservation on the Basic > DHCP page so that 
the IP address of the DMZ machine does not change.
