Introduction

1 Introduction

Intelligent and secure technologies such as dLAN household power grid) and WLAN (wireless networking) have made setting

up a home network fast, easy and economical, while making the installation of expensive, dedicated wiring superfluous. The available performance and effort required for the installation also compares favorably to traditional methods – dLAN expect from a conventional LAN, and installing it is a breeze!

and WLAN technology now attain speeds you would

1.1 What exactly is dLAN®?

dLAN

(direct LAN) uses the household power grid to transfer data

between computers equipped with suitable adapters and other network components. As a result, any power outlet 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 another. Networking via dLAN and secure. The data is automatically encrypted using a key to prevent easy interception by third parties.

(networking via the

1.2 What is WLAN?

WLAN (Wireless Local Area Network) refers to 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 access point is required to set up a network of multiple devices. Such access points are frequently combined in a single device with modems for Internet access and routers to manage network traffic.

devolo® dLAN® Wireless extender

Introduction

The wireless network established by an access point using a specific channel (from 1 to 13) and name (SSID) has a limited range. The range of the access point, which is also known as a "radio cell", is impeded by building walls. In some cases, stable connections are often only possible between WLAN devices within a single room.

As it is not possible to rely on hardware such as network cables (in a LAN) or household wiring (in a dLAN networking naturally presents special security challenges. WLANs therefore use a number of security measures, such as a concealed network name, data encryption and access control via the MAC addresses of the network adapters.

1.3 What the dLAN® Wireless extender has to offer

The devolo dLAN® Wireless extender lets you quickly and simply interconnect WLAN, dLAN

and LAN networks:

As a WLAN access point, the adapter lets your WLAN devices

communicate with an existing LAN or dLAN can extend your wireless network to rooms that were previously out of range.

Thanks to its integrated LAN port, the Wireless extender can also be

used as a WLAN adapter for a single network device.

As a HomePlug adapter, the Wireless extender can connect a single

device such as a computer or printer to the dLAN outlet.

Alternatively, the Wireless extender can be configured as a WLAN

client to connect your home network to an Internet access point

outside of your home.

The dLAN® Wireless extender is easy to use. The device has very few ports:

The AC plug connects the adapter to your power outlet. The WLAN antenna provides the connection to other wireless

network devices. It can be set at an angle of up to 90° in order to optimize wireless communications to the adapter's location.

The Ethernet LAN port can be used to connect a single PC or other

network device using a standard RJ45 patch cable.

2.2 Connecting the dLAN® Wireless extender

To connect the dLAN® Wireless extender, simply plug it into a free power outlet at the desired installation location. Ensure that the adapter is fully inserted in the outlet.

A WEP key consists of a hexadecimal number with exactly 10 or exactly 26 digits (from 0 to 9 and A to F, e.g. "8AF34597FF"). Do not enter special characters such as colons.

Note that the WLAN function is enabled and WLAN encryption is disabled when the device is set to its factory defaults. When enabling encryption, ensure that the WLAN settings (SSID, encryption mode and encryption password) of the access point and those of the clients always match, as otherwise you may exclude devices from your network (unintentionally).

3.4.4 WLAN settings

To use your dLAN® Wireless extender as an access point (see previous section

configured under Overview Settings.

When using your Wireless extender as a WLAN client, all of the options on this page are irrelevant. A message informing you of the current status will be displayed if that is the case.

It is also possible to completely disable the WLAN capabilities of your Wireless extender, for example when using it as a simple dLAN

adapter via

Contrary to popular belief, it is not a problem if multiple access points share a channel. It can even be advantageous to maintain a channel spacing of five numbers from other access points. You should therefore favor channels 1, 6 and 11.

The SSID specifies the name of your wireless network. Others can see this

designation when logging on to the WLAN to identify the correct subnet.

Your wireless network will remain invisible if you activate the Hide SSID

option. In that case, potential network users must know the exact SSID and enter it manually to establish a connection.

devolo® dLAN® Wireless extender

A number of WLAN adapters have difficulties connecting to such invisible wireless networks. If you have problems connecting to a network with a hidden SSID, start by establishing a connection with the SSID visible, then hide the SSID.

If you do not use encryption, not only will all data being transferred from client computers to the Wireless extender in your wireless LAN be unprotected, users will not be prompted for a password when establishing a connection. If you have not set up any other security measures such as WLAN filters (see section 3.4.5), third parties will be able to access your network at

any time and use your Internet connection. Under normal circumstances, you will not notice that this is occurring.

Note that the WLAN function is enabled and WLAN encryption is disabled when the device is set to its factory defaults.

Two standards are available for ensuring secure data communications in

wireless networks. The older and somewhat weaker WEP standard protects

communications using keys consisting of 10 or 26 digits. Simply enter a

sequence of the proper number of hexadecimal characters in the Key field. The more modern WPA/WPA2 (WiFi Protected Access) supports

individual keys consisting of letters and digits with a length of up to 63 characters. These can be simply entered using the keyboard without prior conversion into hexadecimal format, as is the case with WEP. Client access to the Wireless extender can also be restricted to the highly secure WPA2

method by enabling the "Only permit WPA2 (maximum security)"

option.

Be sure to save your changes before leaving the configuration area.

We recommend always encrypting your WLAN connections. Without it, anyone within range can intrude on your home network and use your Internet connection without your authorization. Wherever possible, always choose the stronger WPA/WPA2 encryption method. Do not use the WEP standard unless your wireless devices do not support a higher standard.

3.4.5 WLAN filters

In addition to encryption (see previous section), setting up a WLAN filter can further restrict access to your Wireless extender to selected devices. Even if encryption were disabled, other adapters would not be able to establish a connection.

The WLAN filter should only be used as an additional option. It is useful for restricting access to your wireless network. Without encryption, however, it is still relatively easy for third parties to intercept your data communications.

It consists of six two-digit hexadecimal numbers that are separated by colons (e.g. 6A:54:FA:11:DE:23). The MAC address can generally be found on a label on the network adapter.

The dLAN® password of a specific dLAN® Wireless extender can also be changed via the integrated configuration interface of the adapter (also see

3.4.6). Go to Overview Settings. Enter the desired password twice and click Save.

Assigning a specific password to a single adapter will exclude it from the remaining dLAN

network. If possible, use the dLAN Configuration Wizard to ensure that a single password is used throughout your entire dLAN network.

4.2.3 Step 3: Add dLAN adapters

At this point, add further dLAN® adapters to your home network. You will need the 16-character security codes from the labels on the bottom of the

adapter housings. Enter the code without hyphens in the Security ID field and click Add. If the code is correct, a small icon and the network ID of the

found adapter will appear in the list.

When launching the dLAN® Configuration Wizard again after a successful initial installation – when integrating a new adapter into the network, for example – the application will remember devices and security codes entered in previous sessions. It will therefore not be necessary to enter them again. The Configuration Wizard will display an error message if an adapter entered

Once you have entered the security IDs of your dLAN® adapters, your HomePlug network is complete. All computers and other network devices connected to the adapters by cable should now be able to communicate with one another in the network. If desired, continue with the configuration of the WLAN component of the dLAN

5 Setting up a WLAN network

5.1 Basics

The dLAN® Wireless extender creates a bridge between dLAN® and WLAN networks. The adapter can be used in two operating modes for this purpose:

By default, the Wireless extender is configured to act as a WLAN

access point, sending and receiving data from a dLAN

and other network devices via a wireless connection.

As a WLAN client, it can log onto an existing wireless network and

transfer data to a dLAN other network device via the Ethernet LAN port.

In both modes, the connection between the dLAN other network devices can be pictured as a "wireless cable", i.e. anything that could normally be transferred via a LAN cable can also be transferred via the WLAN. The dLAN

absolutely essential to the operation of the wireless network, we nevertheless

urgently recommend using the various security measures provided by

the Wireless extender to prevent intruders from accessing the network.

To set up the dLAN point, open the adapter's integrated configuration interface in a window of your web browser. If you know the IP address of the device, type it into the

address line of your browser. Otherwise, launch the dLAN Wireless extender configuration application, or open the configuration from the context menu of the appropriate entry in the devolo Informer.

X Change Configuration X WLAN mode.

Do not confuse the input of the SSID and WEP key under the WLAN client item with comparable entries in the WLAN settings (that apply to operation as an access point).

Go to Overview X Change Configuration X WLAN settings. Ensure that WLAN operation is activated. Select one of the available

13 channels for your wireless network.

Contrary to popular belief, it is not a problem if multiple access points share a channel. It can even be advantageous to choose a channel that is spaced four numbers away from those of other access points within range. You should therefore favor channels 1, 6 and 11.

devolo® dLAN® Wireless extender

Setting up a WLAN network

Assign a unique name (SSID) to your WLAN to identify it to your clients. Optionally, you can also hide the SSID. A hidden SSID is an additional security factor, as only those WLAN clients that know the exact name of the network can access it.

Under Overview X Change Configuration X Network settings

address automatically from a DHCP server in the network. Alternatively, you

can disable this option and specify an exact IP address and netmask.

Wireless extender will receive its IP address.

Setting up a WLAN network

While assigning static IP addresses to the devices in your home network and entering the addresses manually can have advantages, a change to the subnet mask may result in the configuration interface of your Wireless extender becoming inaccessible. We therefore recommend retaining the default setting as a DHCP client. If you would like to configure the adapter by entering its IP address directly in the address line of your browser, you can determine its IP number by selecting

If you were previously using a wireless connection to configure the dLAN Wireless extender, the connection will naturally be lost when switching the WLAN mode. Use the LAN or dLAN this case.

5.3 Security in the WLAN

When operating a wireless LAN, special measures are essential to secure the network. Theoretically, anyone with a WLAN adapter within range of your access point could break into your network unnoticed and access your computers and network devices or access the Internet via your account.

to access and configure the adapter in

devolo® dLAN® Wireless extender

Setting up a WLAN network

The dLAN® Wireless extender features a number of security mechanisms that can be used individually or in combination to prevent this.

By selecting a hidden network name (SSID), you can restrict access

to those WLAN clients that know its exact designation. Chapter 3.4.4 of this manual covers this function in detail.

Encryption of your wireless data traffic with WEP – or better yet with

WPA/WPA2 – not only helps restrict access to your WLAN, but also prevents "eavesdropping". For more information on encryption options, please see 3.4.4.

Ensure that all of your WLAN clients support the selected encryption standard. If in doubt, select WEP as the "lowest common denominator".

Finally, you can use the WLAN filters to configure the dLAN

extender to connect only to specified devices using their MAC addresses as identifiers. Also see 3.4.5.
