software portal will appear automatically.
Click Sinus 154 stick and then Dokumentation. The manual will then open.
If the manual does not open: Click the option Acrobat Reader in the initial window and then the
option Installieren (Install). Follow the instructions on the screen. After the Acrobat Reader has been installed, repeat the steps described above.
Initial installation The installation sequence:
Click the option Sinus 154 stick and then Installation. Follow the instructions on the screen. The
T-Com WLAN Manager will then be installed. When the T-Com WLAN Manager has been installed, click Fertigstellen (Finish) and insert the Sinus 154 stick into the free USB slot. You will be asked to install the drivers for the specific operating system which you are using. When you have done this, you must restart the computer. Pay attention to the notice about the Windows XP operating system's own management program. Configure the Sinus 154 stick as described below.
Particular dangers for radio networks A WLAN is particularly susceptible to privacy attacks because anyone can access such a network without any great technical difficulties. Another notebook with a radio adapter is sufficient. For this reason we strongly recommend you to change the SSID, activate the encryption and select a complex code immediately when you put your Sinus 154 stick into operation for the first time. Starting the T-Com WLAN Manager Double-click the symbol in the system tray (on the right-hand side of the task bar). A window will then open with the register cards Einstellungen (Settings), Verbindung (Connection), IP Adresse (IP address), Netz-bersicht (Network overview) and Version (Version). The "Einstellungen" (Settings) tab You can use the "Einstellungen" tab to make all the basic settings which are necessary in order to link up the card to an existing WLAN. In the majority of cases it will only be necessary for you to make settings concerning the encryption. Your settings will only take effect if you click the bernehmen (Apply) button. Every time you click bernehmen, however, the Verbindung (Connection) register card will open. For this reason, it may be too time-consuming if you click bernehmen after each setting. We recommend you to make all of your settings first and then, when you have finished, to click the bernehmen button. You can, of course, confirm every single setting with bernehmen. When this tab is opened for the first time, the Allgemein (General) tab is foremost.
The "Allgemein" (General) tab
Setting up/selecting a profile
If you intend to operate your computer with the Sinus 154 stick in more than one network (alternately), you can set up appropriate profiles. A profile is a combination of settings which are united under a particular name - the profile name. Example: The computer is to be used either in the marketing network, which is, for example, an ad hoc network and in the development network, which is, for example, an infrastructure network. The networks are of varying kinds (ad hoc and infrastructure) and, in addition, the encryption code is not the same. 1 Enter the name you want to give to the profile, e.g. Sinus 154, into the entry field beside Profil. If there is already a name of a saved profile in this field, double-click this name in order to highlight it and then enter the name for the new profile. 2 Click the Speichern (Save) button. If you click the Speichern button after you have made all the other possible settings, these settings will all be assigned to the profile name displayed on this card. If you click the Lschen (Delete) button, the displayed profile will be deleted. Selecting a profile: 1 Click the opening arrow beside the Profil entry field. 2 Highlight the name of the profile you would like to use. 3 Click bernehmen (Apply). The settings which belong to this profile will then become valid.

All computers in the domain of a WLAN (wireless local network, radio network) must have the same identity in order to be recognized by the other computers. It only makes sense to use the SSID of a network which is within your range. 1 (Only if you use more than one profile) Select the profile you would like to assign an SSID to. 2 Click the opening arrow to the right of the SSID entry field. 3 You will then be shown the SSID of all networks which are within range of your computer. Select the SSID you require. If the SSID of the radio network is not displayed although you are sure that you are within its range, this usually means that the access point/router is not transmitting its SSID. In this event, you must enter the SSID manually. 4 Click the Speichern (Save) button beside the Profil entry field. If you have not selected a profile, the selected SSID will be assigned to the current profile. At the time of the initial configuration this will be the default setting (WLAN). If you would like to access another network with your computer and it is within your radio range, you can select this network via the Netzbersicht (Network overview) tab. Then you only have to select the corresponding profile which you set up at an earlier time.
Betriebsmodus (Operating mode)
When you define the operating mode, you are specifying the kind of network environment you are making a connection to with your computer and the Sinus 154 stick: Infrastruktur (infrastructure): A local network in which the computers can communicate with one another via cable as well as radio signals. This is achieved by means of one or more access points (also, for example, routers which have this access function) which are capable of entering other networks. The Infrastruktur setting does not work in ad hoc networks. You cannot set the radio channel because it is dependent upon the access point. Ad Hoc: A local network in which the computers can only communicate directly with one another via radio signals. There is no access to a cable-linked network. The ad hoc setting does not work in infrastructure networks. In this kind of network you have to set the radio channel and all computers must use the same channel. 1 Click the opening arrow beside the Betriebsmodus (Operating mode) field. 2 Select the mode you want to use. 3 Click bernehmen (Apply). 4 Click Speichern (Save) next to the Profil entry field. All computers in the domain of a WLAN (radio network) must use the same transmission rate during a connection in order to be able to communicate. The transmission rate, however, can vary depending upon the strength of the signal (e.g. on account of the distance) or the kind of WLAN access point/router (e.g. a router of the 11 Mbps class (IEEE 802.11b)) being used. The best setting is therefore Auto. 1 Click the opening arrow beside the bertragungsrate field. 2 Select the transmission rate you want to use (recommended: Auto). 3 Click bernehmen (Apply). 4 Click Speichern (Save) next to the "Profil" entry field. The transmission rate will then be assigned to this profile.

Setting the channel

If you are using an ad hoc network, you can define the radio channel on which the computers communicate with one another. If ad hoc is selected, the Kanal (channel) field is activated. You cannot set the radio channel in an infrastructure network because you have to use the channel on which the access point is transmitting and receiving. For this reason, no setting can be made in an infrastructure network. You are using an ad hoc network: Sie verwenden ein Ad Hoc Netz: 1 Click the opening arrow next to the Kanal field. 2 Select the channel you want to use. All computers in an ad hoc network must use the same channel 3 Click bernehmen (Apply). 4 Click Speichern (Save) next to the "Profil" entry field.

Ausblenden (Minimize)

Click the Ausblenden (Minimize) button if you would like to close the window of the WLAN Manager. The radio connection will not be terminated by doing this. You can make the window appear again by clicking the symbol in the system tray or by double-clicking the icon on the desktop.
Switching the radio connection on/off
You can switch on/off the radio signal from your Sinus 154 stick by clicking the Funk Ein/Aus (Radio ON/OFF) button. If the radio signal has been switched off, your computer can no longer be reached by the other computers in the network.

Hilfe (Help)

By clicking the Hilfe (Help) button you can get online assistance if you have any questions.

Security

Click the Sicherheit (Security) tab in the Einstellungen (Settings) register card. On this tab you can find all the possible settings which ensure security for your PC when operating in the WLAN. When the device leaves the works the encryption is deactivated. You are not normally able to communicate in the WLAN because the access points or the router in the radio network protect against unauthorized access, in particular by means of encryption. Your Sinus 154 stick therefore has to be set up in accordance with the security settings of the access point/router. You can find out what these settings are from the administrator of the network you would like to access.

Encryption

Click the opening arrow next to the Verschlsselung (Encryption) field. You can see what methods are available to you in the menu which now appears. You can connect up to a network which uses one of these security measures. The following options are available: Aus(Off): No encryption. The computer cannot gain access to a network which is encrypted and the computer cannot be reached by an encrypted network. The computer is fully unprotected against unencrypted networks (first step in hacking attempts). Not recommended. WEP: (Wired Equivalent Privacy = privacy comparable to that of a wired system) This is an encryption method which can be applied regardless of the operating system being used. WPA-PSK: (Wi-Fi Protected Access Pre-Shared Key = privacy comparable to that of a wired system, but greater than WEP) using a varying encryption key, but a shared starting key) A method similar to WPA. The change arises from a code mix from the client-related, static pre-shared key. WPA with Tiny Server: Here a server in the local network takes over the task of authentication between the communicating devices. In addition to a password, the computer must identify itself by means of a user name. You can obtain this name from your network administrator who has already stored it on the Tiny Server. WPA2 with RADIUS Server: In this case an external server takes over the task of authentication between the communicating devices in your network. As a client in a network which has been protected in one of these ways, you personally have no influence upon the method being used. You must comply with the specifications you have been given and make the corresponding settings. The encryption method and the corresponding encryption key must be the same for all computers within the network in order that the PCs can communicate with one another. When the stick leaves the works the encryption is set to AUS (OFF) and accordingly none of the input fields are active. For this reason you will not - as a rule - be able to access an existing network which has already been configured. The T-COM WLAN Manager icon in the Quick Launch bar is red if there is no connection.

If WEP is employed in the WLAN:
You cannot enter any key you like in any way you like. Which key you use and with which code number depends upon how it was generated on the access point/router. For security reasons there are no rules determining how a key is calculated (different algorithms are used to calculate the code). When allocating the code via Schlsselwort (key string), check whether the access point into the WLAN is a Sinus 154 DSL or T-Sinus 1054 DSL. If this is not the case, you must use the hexadecimal key with the corresponding code number which was generated from the key string for these computers. 1 Click the opening arrow next to Verschlsselung (Encryption) and select WEP in the menu.
2 Click the opening arrow next to Verschlsselung and select either 64 bit or 128 bit as your key security level. 3 To enter the key you have the following possibilities: If the access point/router is a product of the T-Sinus or Sinus series (130, 154, 1054, 530, 730) and the key was generated by means of a key string, you can click the box in front of Schlsselwort (key string): This activates the input field allowing you to enter the string of letters which were used on the access point/router. Then you only have to specify the correct code number in the bottom field (Standardschlssel). If the access point/router does not belong to one of the above-named series, click the opening arrow beside the input field Schlsseltyp (key type) and select either HEX (hexadecimal = numbers 0-9 and letters A-F, 10 characters) or ASCII (alphanumerical characters of the ASCII code, maximum of 32 characters). Then enter the value used in the network, as specified, into the Standardschlssel (standard code) field.
4 Click bernehmen (Apply).
If WPA with preshared key is employed in the WLAN: There are two ways in which you can employ WPA with preshared key: The menu option WPA mit Preshared Key uses the TKIP protocol, the menu option WPA2 mit Preshared Key employs the AES protocol. Which of these you use is dependent upon your access point.
1 Click the opening arrow next to Verschlsselung (Encryption) and select the function you require in the menu.
2 Enter the key which is used in your network in
the Pre-shared Key field.

3 Click bernehmen (Apply).
All values you enter here must correspond with those being used in the network. If you do not know what these values are or where you can find them out, ask your network administrator or, if you have the authorization, check the configuration settings of the access point/router.
If WPA with Tiny Server is employed in the WLAN:
2 Enter the name intended for this computer in the
Benutzername (User name) field.
3 Enter the password used in the network in the
Passwort (Password) field.
You may also have to stipulate the authentication protocol (EAP = Extensible Authentication Protocol = extended security for the PPP protocol). You can choose between PEAP and TLS. In addition, you can also specify the certification (Zertifikat) the server uses and whether a tunnel is employed. In order to do so, click the Details button in the Details section of the WPA2 with Tiny Server window. Then click the respective opening arrow of the EAP, Zertifikat and, if applicable, Tunnel selection fields and select the setting which is stipulated for the network if the default setting is incorrect. All values you enter here must correspond with those being used in the network. If you do not know what these values are or where you can find them out, ask your network administrator or, if you have the authorization, check the configuration settings of the access point/router.
If WPA with RADIUS Server is employed in the WLAN: There are two ways in which you can employ WPA with RADIUS Server: The menu option WPA mit RADIUS Server uses the TKIP protocol, the menu option WPA2 mit RADIUS Server employs the AES protocol. Which of these you use is dependent upon the Tiny Server in your network.
1 Click the opening arrow next to Verschlsselung (Encryption) and select the menu option WPA mit RADIUS Server.
2 Click bernehmen (Apply).
You will be provided with the data which are necessary for the RADIUS server by your service provider and these must then be defined on your router. Under circumstances you may have to define the authentication protocol (EAP = Extensible Authentication Protocol = extended security for the PPP protocol). You can choose between PEAP and TLS. In addition, you can also specify the certification (Zertifikat) the server uses and whether a tunnel is employed.
In order to do so, click the Details button in the Details section of the WPA2 mit RADIUS Server window. Then click the respective opening arrow of the EAP, Zertifikat and, if applicable, Tunnel selection fields and select the setting which is stipulated for the network if the default setting is incorrect. All values you enter here must correspond with those being used in the network. If you do not know what these values are or where you can find them out, ask your network administrator, the service provider of the RADIUS server or, if you have the authorization, check the configuration settings of the access point/router.

Status tab This register card gives you information about the status of the network. No settings can be made here. Zugeordnete BSSID (MAC (Assigned BSSID (MAC) tells you hexadecimally the identity of the network in the form of the MAC address of the access point. This information helps a network expert to find any possible faults. SSID shows you the identity of this profile. It is only possible to make a connection if the network has the same SSID (this can be established by looking at the Netz-bersicht (Network overview) register card (see page 25)). bertragungsrate (Transmission rate) tells you the present speed at this time in the network. Kanal (Channel) tells you the radio channel which is being used. In the Durchsatz (Throughput) field you can see the data traffic in the network in the form of the coming (Empfangsfragmente) and going (Sendefragmente) data packages. IP Einstellung (IP setting) tab This card provides you with important information about the IP addresses (Internet protocol TCP/IP) in your network. The network administrator can use this information to check the computer and the assignment within the network and, if necessary, to coordinate. Via the IP Adresse zurcksetzen (Reset IP address) and the IP Adresse aktualisieren (Refresh IP address) buttons the displayed IP addresses in the network can be brought up to date. This may become necessary if you change over to another network. In this event it is possible that your Sinus 154 stick will remember the previous addresses. By means of these buttons you can bring the system up to date.
Signalstrke (Signal strength) and Rauschen (Interference) tell you whether the network is stable. t
Netzbersicht (Network overview) tab This register card shows you all the radio networks which are within your range. SSID tells you the recognized access points in the network which can be accessed, but only if the SSID of the access point or router concerned has not been suppressed. BSSID tells you the MAC address of this access point. Kanal (Channel) tells you the radio channel which each network is using. Verschlsselung (Encryption) of the network is indicated by a closed (encrypted) or open (not encrypted) lock. Signal shows you the strength of the signal. You can recognize immediately whether the access point is near enough to be accessed without any problems. Betriebsmodus (Operating mode) tells you the type of network: infrastructure network, ad hoc network. bertragungsmodus (Transmission mode) shows you whether the network concerned supports the fast (802.11g) or the slower (802.11b) mode. Aktualisieren (Refresh). If you click this button you can scan the network again and have the up-dated information displayed. This can be useful if are operating a mobile computer and you would like to find out which networks are currently within your range. If you double-click one of the displayed networks, the Einstellungen (Settings) register card will open. If the network is encrypted, a window will open informing you of this. If you use either the operating system Windows 98 or ME, this may appear in the English language. If you know the network and you have already set up a profile for it, select the profile name which you have given to the network and then click bernehmen (Apply). The stored data for this network will then be called up and the computer will be connected up to the network.

Version tab This register card shows you the data about the drivers and the software. This information can be important if you should need to contact the Technical Customer Support at any time. No settings can be made on this register card.
