Introduction
Features
Easily Extend Your Existing Network and Audio Setup
The DCH-M225 Wi-Fi Audio Extender is a portable plug-in repeater that lets you extend an existing wireless network. It also
has the ability to stream your music library to anywhere within your extended wireless network. Tiny yet powerful, it supports
Wireless N speeds of up to 300 Mbps in a device that ts in the palm of your hand.
Compact, Convenient Design
The DCH-M225 ‘s compact design is ideal for use at home or a small oce, as it does not take up much space and is ready to
use by simply plugging it in. The repeater’s small form means it can easily be plugged into a power outlet without blocking
other outlets while its wall wart design saves you the hassle of dealing with a power cord. Its sleek, unobtrusive appearance
means it blends easily into the background.
Conveniently Stream Audio
Expanding your audio capabilities has never been easier with the help of the DCH-M225. With support for both DLNA and
AirPlay, simply plug in your speakers and you’ll be able to stream audio to anywhere within your wireless network. The Wi-Fi
WMM quality of service protocol ensures that you’ll have no issues with bandwidth when streaming audio and performing other
tasks such as surng the Internet, checking email, or online gaming.
Simple Setup
Through its easy-to-use web-based user interface, you can quickly and easily connect the DCH-M225 to an uplink router,
congure the extender wireless network, and manage the administrative settings. The setup wizard will even guide you through
the setup process, getting your extended wireless network up and running in no time.
* Maximum wireless signal rate derived from IEEE Standard 802.11n and 802.11g specications. Actual data throughput will vary. Network conditions and environmental factors,
including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will adversely
aect wireless signal range.

Section 1 - Product Overview
What is a Wireless Extender?
The DCH-M225 acts as a repeater to extend the range of an existing wireless network to provide better signal for parts of
your home or oce that may have poor or no reception. Your existing wireless signal will be re-broadcast by the DCH-M225,
allowing you to reach the farthest corners of your home or oce . The extended network can simply use the same network
credentials as the existing network, or you can specify a dierent network name and password, giving you the exibility to
control network access.
This purpose of this product is to create a constant network connection for your devices. As such, it does not have a standby
mode or use a power management mode. If you wish to power down this product, please simply unplug it from the power
outlet.

Wireless Installation Factors
The Wi-Fi Audio Extender lets you extend the reach of your existing wireless network, allowing you to work wirelessly from
more places in your home or oce. 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 extender and other network devices to a minimum - each wall or ceiling can
reduce your adapter’s range by up to 98 feet (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. At a 45-degree angle, a wall that is 0.5 meters thick (1.5 feet) appears to be
almost 1 meter (3 feet) thick. At a 2-degree angle it can appear over 14 meters (45 feet) 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 can 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 2.4 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.

Troubleshooting
This section provides solutions to problems that can occur during the installation and operation of the DCH-M225. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the Wi-Fi Audio Extender (dlinkap.local for example), you are not connecting to a website nor
do you have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer
must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 7 or later
• Firefox 12.0 or later
• Safari 4 or later
• Google Chrome 20.0 or later
• Make sure that you are connected to the same wireless network which is listed on the base of the DCH-M225. If you have an
active wired LAN Ethernet connection, try temporarily unplugging the Ethernet cable from the computer you are using, as
this may eliminate possible conicts from having two simultaneous connections on the same computer.
• Disable any Internet security software running on the computer. Software rewalls such as ZoneAlarm, BlackICE, Sygate,
Norton Personal Firewall, and Windows® XP rewall may block access to the conguration pages. Check the help les included
with your rewall software for more information on disabling or conguring it.

• Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore
the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing
is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management interface. Open your web browser and enter the address of your extender (http://dlinkap.
local) in the address bar. This should open the login page for your web management. If the DCH-M225 is not connected to
an uplink router, you can try accessing the web interface using the default IP address http://192.168.0.50.
• If you still cannot access the conguration, unplug the extender from the power outlet for at least 10 seconds and plug it
back in. Wait about 30 seconds and try accessing the conguration. If you have multiple computers, try connecting using a
dierent computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your extender. Unfortunately this process will change all your settings back to the
factory defaults.
To reset the extender, locate the reset button (hole) on the underside panel of the unit. With the extender powered on, use
a paperclip to hold the button down for 10 seconds. Release the button and the extender will go through its reboot process
(indicated by the LED turning red). Wait about 30 seconds to access the extender. The default IP address is http://dlinkap.
local. When logging in, the username is admin and leave the password box empty.

Appendix A - Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link
wireless family of products will allow you to securely and conveniently access your network. You will be able to enjoy the
freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of
wires. Wireless LANs are used increasingly in both home and oce environments, and public areas such as airports, coee shops
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently.
Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapters used on laptop and desktop
systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to
use servers, printers or an Internet connection supplied through the wired LAN. A wireless router is a device used to provide
this link.

Tips
Here are a few things to keep in mind when you are installing your Wi-Fi Audio Extender.
Centralize the extender’s location
For best performance, make sure you place the extender in a centralized location within your desired usage area. Try to place
the extender so that there are minimal obstructions between it and the uplink router. If possible, use an elevated power outlet,
so the signal can be dispersed more easily. If you have a large home or usage area, you may need several extenders in order
to achieve optimal coverage.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the extender.
This can signicantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let your neighbors or intruders connect to your wireless network. Secure your wireless network by utilizing the WPA or
WEP security feature on the extender and uplink router. Refer to the relevant sections of this manual for further details.
