Section 1 - Product Overview
Introduction
D-Link, the industry leader in wireless networking, introduces another breakthrough in wireless connectivity. The
D-Link DIR-280 Wireless G Router which is capable of transferring data with a maximum wireless signal rate of up to 54Mbps*
in the 2.4GHz frequency — the same wireless frequency as 802.11b. The D-Link DIR-280 Wireless G Router also offers four
Ethernet ports to support multiple computers.
The advanced wireless technology built into the DIR-280 Wireless G Router offers data transfer speeds with a maximum wireless
signal rate of up to 54Mbps* through its wireless channels allowing streaming videos and other high bandwidth applications, such
as online gaming events, to operate without the hassle of Ethernet cables. The ability to use high bandwidth applications also makes
streaming real-time programs more enjoyable and more efcient.
With the DIR-280 Wireless Router’s built-in advanced Firewall, threats of hackers penetrating your network are minimized. Features
like Access Control and Website Filtering are useful tools to prevent other unwanted intruders from connecting to your network
or browsing restricted sites.
The easy-to-use Conguration Wizard takes only minutes to setup and guides users step-by-step through conguring the DIR-
280. With all the versatile features and a user-friendly utility, the DIR-280 Wireless G Router provides an enhanced networking
experience.
* Maximum wireless signal rate derived from IEEE Standard 802.11g specications. Actual data throughput will vary. Network conditions and environmental factors,
including volume of network trafc, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will
adversely affect wireless signal range.

Section 1 - Product Overview
Faster Wireless Networking - The DIR-280 provides up to 54Mbps* wireless connection with other 802.11g
wireless clients. This capability allows users to participate in real-time activities online, such as video streaming,
online gaming, and real-time audio. The performance of this 802.11g wireless router gives you the freedom of
wireless networking at speeds 5x faster than 802.11b.
Compatible with 802.11b and 802.11g Devices - The DIR-280 is still fully compatible with the IEEE 802.11b
standard, so it can connect with existing 802.11b 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 the URL.
Secure Multiple/Concurrent Sessions - The DIR-280 can pass through VPN sessions. It supports
multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-280 can securely access
corporate networks.

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.

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.

8D-Link DIR-280 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.

9D-Link DIR-280 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.
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 conguration 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.
