1 Introduction

This chapter gives you an overview of the new dLAN technology and a brief introduction to the dLAN duo.

1.1 What exactly is dLAN?

There is now a new alternative to the well-known wired LAN and Wireless LAN network technologies currently used in home networking: dLAN (direct LAN, i.e. directly networked). dLAN is home networking using the electric wiring already installed in the building.

Cost factor and transmission quality

dLAN is an economical and easy-to-use networking technology. You don't need to lay cables and you can connect to the home network at every power point.

The dLAN technology modulates and demodulates additional frequencies on the power lines. Modulation and demodulation is a well-known and proven method of data transmission, which has been in use in other applications for a number of years. Now it is used to set up Internet and network accesses in the home or office. Depending on the damping factor, distances of up to 200 meters can be covered.

With a maximum data rate of 14 Mbps and symmetrical upload and download speeds, dLAN is comparable to traditional Ethernet network solutions and the current WIFI ^™ wireless standard for home applications.

Data security and radiation

For the sake of security, the DES_pro encryption is used to guarantee secure data transfer within the network.

dLAN devices from devolo meet the stringent EU industrial standards and comply with the current standards for electromagnetic radiation.

1.2 What does the dLAN duo offer you?

Powerful and flexible

Ethernet or USB? This question no longer arises with the dLAN duo. Featuring both Ethernet and USB ports, the dLAN duo combines the features of dLAN Ethernet and dLAN USB devices. The result is new freedom and flexibility: it's no longer necessary to settle on one or the other connection technology. For example, PCs or laptops can be integrated into a dLAN network using either of the ports—depending on which one is available.

You can find examples of possible networks and general information in the chapter 'All about the home network'.

Simple installation

• Cookies—Many websites store small files on your computer, so-called cookies. These files may contain personal information such as log-in data, passwords or credit card numbers.

• Temporary Internet files—Temporary files are stored on your hard drive while you surf the Net. Over time, these files take up a considerable amount of space.

• History files—Internet Explorer records your surfing activity over a period of days or weeks. This can be practical, but it also takes up space and can be undesirable in many cases.

• Stored form information—Internet Explorer stores information that you enter in forms and can auto-complete this information in the future.
• Stored passwords—Passwords can also be stored and automatically inserted together with usernames in subsequent log-in procedures. While this is convenient, it's also dangerous—especially in connection with bank transactions. Sensitive information such as this should only be stored locally in special programs designed for this purpose.
• Document history—Internet Explorer maintains lists of open documents and visited websites. This information is generally no longer needed.

Please note that EasyClean only supports Microsoft Internet Explorer.

6 Additional regulations

a) The above conditions define the complete scope of devolo's legal liability.

b) The warranty gives no entitlement to additional claims, such as any refund in full or in part. Compensation claims, regardless of the legal basis, are excluded. This does not apply if e.g. injury to persons or damage to private property are specifically covered by the product liability law, or in cases of intentional act or culpable negligence.

c) Claims for compensation of lost profits, indirect or consequential detriments, are excluded.

d) devolo is not liable for lost data or retrieval of lost data in cases of slight and ordinary negligence.

e) In the case that the intentional or culpable negligence of devolo employees has caused a loss of data, devolo will be liable for those costs typical to the recovery of data where periodic security data back-ups have been made.

f) The warranty is valid only for the first purchaser and is not transferable.

g) The court of jurisdiction is located in Aachen, Germany in the case that the purchaser is a merchant. If the purchaser does not have a court of jurisdiction in the Federal Republic of Germany or if he moves his domicile out of Germany after conclusion of the contract, devolo's court of jurisdiction applies. This is also applicable if the purchaser's domicile is not known at the time of institution of proceedings.

h) The law of the Federal Republic of Germany is applicable. The UN commercial law does not apply to dealings between devolo and the purchaser.
