What is a Wireless Repeater?
In Repeater Mode, the DIR-608 works with your existing networking equipment to provide Wi-Fi for parts of your home or
oce that may have poor or no reception. It works as a wireless repeater by connecting to your existing wireless network and
rebroadcasting its signals for your devices to connect to. Using the DIR-608 as a wireless repeater will reduce the total amount
of wireless bandwidth available.
Place the DIR-608 in an area where you wish to get Wi-Fi, but is reachable by your existing wireless signal.

• Extending your current network.
• Bringing Wi-Fi to an area it doesn't currently reach.
• Providing better signal for parts of your home or oce that may have poor reception.
• Connecting wired Ethernet devices which do not have a built-in wireless, such as smart TVs, game consoles, or DVRs.
• Networking areas where cables are impractical.
Note: Extending by Wi-Fi reduces the total available amount of wireless bandwidth available.
To use your DIR-608 as a Wireless Repeater, refer to Hardware Setup - Wireless Repeater on page 15.

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.
• Congure the router with the computer that was last connected directly to your Internet connection. Verify that
it is connected to the Internet before connecting additional devices.
• If your ISP provided you with a modem/router combo, you will need to set it to “bridge” mode so the router can
work properly. Please contact your ISP or refer to the user manual for your modem/router device.
• 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 o 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 Internet Service
Provider (ISP) to change connection types (USB to Ethernet).
• If connecting to a DSL modem, make sure to have your DSL service information provided by your ISP handy. This
information is likely to include your DSL account's username and password. Your ISP may also supply you with
additional WAN conguration settings which might be necessary to establish a connection.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time
to label each cable or take a picture of your existing setup before making any changes.
• 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.
• If you are using this device as a wireless repeater, you may need to use trial and error to determine an acceptable
placement location.

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 to 90 feet (1 to 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 (0.5 meters) thick, 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 dierence. A solid metal door or aluminum studs may have a negative eect 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 to 6 feet or 1 to 2 meters) from electrical devices or appliances that generate
RF noise.
5. If you are using 2.4 GHz 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 2.4
GHz 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.
6. Using the device as a wireless repeater will reduce the total amount of wireless bandwidth available.
