2Introduction
dLAN is an intelligent, secure technology that lets you
set up a home network easily, quickly and economical-
ly via your household electrical wiring, without the
need for complex and expensive dedicated cabling.
Fig. 1 devolo dLAN and Wi-Fi throughout the home
2.1 What exactly is dLAN?
The dLAN (direct Local Area Network) uses the house-
hold power grid to transfer data between computers
and other network components equipped with suitable
adapters. As a result, any electrical socket can be used
as a network access point. The data is modulated prior
to transfer and sent as a signal via household power
lines. State-of-the-art technology ensures that the
power and data networks do not interfere with one an-
other. Networking via dLAN is fast and secure. The
data is encrypted using a key to prevent interception by
third parties.
2.2 What is WLAN?
WiFi refers to a WLAN (Wireless Local Area Network),
the use of radio technology to network computers and
other devices. While it is possible to wirelessly connect
computers in pairs ("peer-to-peer", p2p), a central ac-
cess point is usually required to set up a network of
multiple devices. This turns a WiFi router into an access
point as well as a modem for Internet access and into
a router for acting as a go-between within the net-
work.
The wireless network established by an access point
has only limited range. The range of the access point,

10 Introduction
devolo dLAN 550+ WiFi
which is also known as a "radio cell", is impeded by
building walls. In some cases, stable connections are
often only possible between WiFi devices within a sin-
gle room.
Since it is not possible to rely on hardware such as net-
work cables (in a LAN) or household wiring (in a dLAN)
to control access to a WiFi network, wireless network-
ing naturally presents special security challenges. WiFi
networks therefore use a number of security measures,
such as a concealed network name (SSID - Service Set
Identifier), data encryption and access control via the
MAC addresses of the devices (clients).
2.2.1 Wi-Fi or WLAN?
Wi-Fi is an invented brand name of the Wi-Fi Alliance,
a consortium that certifies devices with wireless inter-
faces. In many countries, Wi-Fi is also used synony-
mously with WLAN, which if taken strictly, is incorrect,
because Wi-Fi designates the wireless standard and
WLAN the wireless network.
2.3 What exactly is range +?
Range + is a technology for devolo dLAN products.
Unlike conventional Powerline technology, range+
Technology uses all three lines (neutral, earth wire,
phase) of the electrical circuit, making use of the full
physical potential. Thanks to patented signal coupling,
data transmission over the mains supply is optimised.
This results not only in a more stable Internet connec-
tion that is less sensitive to interference, but also in-
creased range.
2.4 What does WiFi Clone mean?
WiFi Clone is a technology for devolo WiFi products
that makes it extremely easy to integrate new devices
into an existing WiFi network. For this purpose, just
plug the corresponding adapter into an available elec-
trical socket and press the encryption button (for older
models, the WPS button). The devolo WiFi devices now
automatically exchange their WiFi credentials with the
existing WiFi router and synchronise SSIDs, keys and
any configured settings, such as parental control and
time control settings.
2.5 What is WiFi Move Technology?
WiFi Move Technology is a function for devolo WiFi
products that expands and optimises the existing WiFi
network. If multiple devolo WiFi devices are used,
these act as access points that connect via Powerline.
The devolo WiFi products automatically connect to the
access point with the strongest signal. This creates a
fast and stable WiFi network throughout the home.

Setting up WiFi Clone and using
WiFi Move Technology
WiFi Move Technology is a function for synchronising
the WiFi settings of all WiFi adapters. Activate the syn-
chronisation either using the functions on the configu-
ration interface (see Chapter 4.3.6 WiFi Clone and
WiFi Move) or at the touch of a button on the adapt-
er.
햲First press the encryption button with the home
icon (for about 1 second) on an existing
dLAN 550+ WiFi that has the entire WiFi con-
figuration which is to be transferred to all other

at least two dLAN devices
(200 Mbps, 500 Mbps, 600 Mbps or
1200 Mbps).

18 Initial use
devolo dLAN 550+ WiFi
3.3 Connecting the
dLAN 550+ WiFi
The device may be used only indoors.
Before the networking procedure, write down
the WiFi key of the dLAN 550+ WiFi. You can
find this unique key on the rear side of the
housing.
Enter the WiFi key in your laptop, tablet or
smartphone later as a network security key to
establish an encrypted connection with the WiFi
network dLAN 550+ WiFi.
In the following sections we describe how to connect
the dLAN 550+ WiFi and integrate it into the network.
We clarify the exact procedures based on potential net-
work scenarios:
3.3.1 Starter Kit and addition – Setting
up a new dLAN network
햲Connect the dLAN 550 duo+ to your Internet
access device's network jack (e.g. WiFi router).
햳Plug the dLAN 550+ WiFi into a wall socket. As
soon as the indicator light of the encryption but-
ton with the home icon is flashing red at regular
intervals (after approx. 50 sec.), the adapter is
ready to operate but not yet integrated into the
dLAN network.
To disconnect devolo devices from the mains supply,
pull the device itself or its mains plug from the power
outlet.
The electrical socket and all connec-
ted network devices should be
easily accessible so that you can
pull the mains plug quickly if needed.
Connecting the dLAN 550 duo+ and
dLAN 550+ WiFi to a dLAN network
Before you can use the adapter in a dLAN network, first
you have to connect it as a network. This is accom-
plished by using a shared dLAN password. This forms
a delimited dLAN network. Shared use of the dLAN
password serves both as access control to the dLAN
network as well as the encryption, and thereby the in-
terception protection, of the transmitted data.

The dLAN password can be set in different ways:
dLAN network encryption at the touch of a
button
햴First press the encryption button (for about 1
second) of the dLAN 550 duo+ and then,
within 2 minutes, press the encryption button
with the home icon of the dLAN 550+ WiFi (for
about 1 second).
햵As soon as the indicator light in the encryption
button lights up white, your dLAN network is set
up and protected from unauthorised access.
or
dLAN network encryption by entering the dLAN
password in the configuration interface.
More information can be found in Chapter 4.5 Device
configuration.
3.3.2 Addition – Expanding an additional
network
햲Plug the dLAN 550+ WiFi into a wall socket. As
soon as the indicator light of the encryption but-
ton with the home icon is flashing red at regular
intervals (after approx. 50 sec.), the adapter is
ready to operate but not yet integrated into the
dLAN network.
To disconnect devolo devices from the mains supply,
pull the device itself or its mains plug from the power
outlet.
The electrical socket and all connect-
ed network devices should be easily
accessible so that you can pull the
mains plug quickly if needed.
Integrating the dLAN 550+ WiFi into an existing
dLAN network
Before you can use the dLAN 550+ WiFi in your dLAN
network, first you have to connect it to your existing
dLAN devices as a network. This is accomplished by us-
ing a shared dLAN password. This forms a delimited
dLAN network. Shared use of the dLAN password
serves as access control to the dLAN network as well as
the encryption of the transmitted data. The dLAN pass-
word can be set in different ways:
dLAN network encryption at the touch of a but-
ton (home icon)
햳First press the encryption button (for about 1
second) on a device in your existing network and
then, within 2 minutes, press the encryption
button with the home icon on the new
dLAN 550+ WiFi (for about 1 second).
