Step 1:
Install the ISDN ADSL Splitter
The ADSL technology uses the existing telephone line for the broadband entrance. With the
ISDN installation a ISDN ADSL-Splitter must be installed to separate the frequency ranges of
ADSL and ISDN and to prevent disturbances at ISDN phones or fax machines. Use for installati-
on the provided ISDN ADSL-Splitter.
Important note:
- With an ISDN installation only one ISDN ADSL-Splitter is needed for the entire ISDN
installation.
- For Phones or fax machines with ADSL and ISDN there is no Line-Filter needed.
- Please contact your support-technician if your ISDN-NT (ISDN Networkterminator) is
not equipped with a plugged incoming line.

Connect the ADSL WLAN Router to the exchange connection
1. Remove the plug on the telephone or the fax machine from the telephone socket.
2. Insert the ADSL-Splitter into the telephone socket. Plug the plug of the ADSL-Splitter cable
(enclosed, mostly black) into the “Phone” (F) plug of the telephone socket and the other
plug into the “Line” (Amt) plug of the ADSL-Splitter.
3. Set up the connection between the ADSL-Splitter and the ADSL Modem. To do this, insert
the end of the ADSL cable (gray) into the socket of the ADSL-Splitter with the "DSL"
(Modem) symbol.
Insert the other end of the ADSL cable (gray) into the socket on your ADSL WLAN Router
marked "DSL".
4. Set up the connection between the ADSL-Splitter and the ISDN-NT. To do this, insert the
available phone cord (same construction as the ADSL-Splitter cable) into the middle plug of
the ADSL-Splitter. The middle plug is marked with a none crossed symbol of a phone.
Connect the end of the phone cable into the “Line” plug of the ISDN-NTBAs.

USB driver installation
The USB driver is only working on the following operating system (OS):
Windows 98, Windows 98 SE, Windows ME, Windows 2000 and Windows XP.
If your ADSL WLAN Router is NOT equipped with an Ehternet interface you have to install first
the USB driver in order to be able to configure your ADSL WLAN Router. For the driver installa-
tion proceed as follows:
Windows 98 users need the Windows 98 CD-ROM to complete the
installation.
1. Insert the SIEMENS installation CD-ROM in your CD-ROM drive.
The CD will be startet automatically.
In case the “setup wizard” does not start automatically, open a Run window via
Start --> Run and enter the path x:\USB_Driver\windows\setup.exe, where xrepre-
sents the drive letter of the CD drive.
2. Click on Run or Setup.
3. Connect the USB cable to your ADSL WLAN Router. The driver will be installed auto-
matically.
Note for Windows 98 users: If prompted, you need to insert the Windows 98 CD-
ROM in your CD-ROM drive to complete the installation.
4. You will be asked whether the PC should be restarted. Click on Close.
5. Click on Finish.

Step 4:
Configure the PC (TCP/IP settings)
Introduction
In step 4, you will learn how to configure your computer to communicate with the SIEMENS
ADSL WLAN Router.
To do this, you will need to configure your PC’s network settings to obtain an IP address auto-
matically. Computers use IP addresses to communicate with each other across a network or
the Internet.
Find out which operating system your computer is running, such as Windows 98, Windows ME,
Windows NT4, Windows 2000, Windows XP, Windows Vista or Macintosh OS 9.x, 10.x.
You will need to know which operating system your computer is running. You can find out by
clicking on Start -> Settings. (If your Start menu doesn’t have a Settings option, you are run-
ning Windows XP or Windows Vista. In this case you can select the Control Panel directly from
the Start menu.) Then, click on Control Panel and double-click on the System icon.
Click the Cancel button when done.
Once you know which operating system you are running, follow the directions in this step for
your computer’s operating system.
The next few pages tell you, step by step, how to configure your TCP/IP settings based on the
type of Windows or Macintosh operating system you are using.

1) Choose a TCP/IP entry whose name contains Ethernet adapter. Do not choose
a TCP/IP entry whose name is PPPoE, VPN or other.
2) If there is no TCP/IP line listed, refer to the User Manual on your Aethra CD-ROM
to install TCP/IP now.
Windows 98 users need the Windows 98 Installation CD to complete the installa-
tion.
1. Click on Start -> Settings -> Control Panel.
Double-click on the Network icon to open the
Network screen.
2. Select the Configuration tab and highlight the
TCP/IP line for the applicable Ethernet

5. Click again on OK. Windows may ask you for
the original Windows Installation disk or addi-
tional files. Supply them by pointing to the cor-
rect location, e.g. D:\win98, where “D” repre-
sents the letter of your CD-ROM drive.
6. If Windows asks you to restart your PC, click on
Yes. If Windows does not ask, restart your
computer anyway.

Step 6:
Configure the Wireless LAN (WLAN) of your
ADSL WLAN Routers
Using radio waves, a wireless network introduces some security risks which are not present in
a wired network; an unauthorized third party can intercept transmitted data, gain access to
your wireless network. In order to make your wireless network as secure as a wired network
you should apply, at least, the following guidelines.
To guarantee that your data is transmitted in a private manner, you should use the highest
possible security settings in your WLAN. Make sure that each PC on your wireless network uses
the same key as your access point.
The following example illustrates the encryption via ‘WPA-PSK’. Note: you must configure the
Access Point first and after that all connected devices.
1. Click Wireless and afterwards Security. Be sure, the Enable Wireless Network option is
selected.
2. Click Wireless and afterwards Security.
