The Gigaset SE366 WLAN

Your Siemens Gigaset SE366 WLAN is a powerful but easy-to-use device that connects your PC (WLAN) or your local network (LAN) to the Internet without the need for wires (via a DSL or cable modem). You can connect your PC wirelessly to the Gigaset SE366 WLAN and create a wireless local network (WLAN). For network security, wireless transmission can be encrypted using the WPA standard or 64/128-bit WEP. The Gigaset SE366 WLAN allows several users to access the Internet simultaneously. A single user account can be shared, if your Internet Provider permits this. If you want to surf the Internet at the lowest possible cost, then the Gigaset SE366 WLAN is a convenient and effective solution. You can connect a DSL or cable modem to the WAN interface of your Gigaset SE366 WLAN. Despite its extensive range of functions, the Gigaset SE366 WLAN is easy for both experts and non experts to handle. It can be configured and made operational within a few minutes. The Gigaset SE366 WLAN provides the new WPS function for wireless connections of PCs or notebooks. You can activate this function with the registration button. If the other clients in your wireless network, such as the Gigaset PC Card 300, also support WPS, you can connect with one click only.

Local networks with Gigaset products
You can use the Gigaset SE366 WLAN to set up a local area network, e.g. a home network. All the PCs in this network can communicate with each other and have access to the Internet. Gigaset SE366 WLAN Modem

Windows XP

There are various ways in which you can set up the network with a Gigaset SE366 WLAN. You can
u set up a wired local area network (Ethernet) and allow the connected PCs access to
the Internet (see page 9),
u set up a wireless local network (WLAN) and allow the connected PCs access to the
Internet (see page 10), (see page 12).
u set up a local network comprising wireless and wired network components
The Gigaset SE366 WLAN Wired local area network (Ethernet)
In a wired local area network, PCs communicate with one another via an Ethernet cable. The Gigaset SE366 WLAN establishes the connection between the PCs, which you can connect to the four Ethernet LAN ports. The PCs must be equipped with a network socket (Ethernet). New PCs frequently already have this socket. For older PCs you will need to install an Ethernet network card. An Ethernet cable is used to connect the PC to the Ethernet LAN socket on the Gigaset SE366 WLAN. One cable is supplied with the device; you can obtain additional Ethernet cables from your retailer. The Gigaset SE366 WLAN allows all PCs to access the Internet simultaneously. Gigaset SE366 WLAN

Ethernet

The Gigaset SE366 WLAN Wireless local area network (WLAN)
In a wireless local area network (WLAN), PCs are linked without wires or cables. For this, the PCs have to be equipped with a wireless network adapter (WLAN adapter) such as a Gigaset PC Card 300 or a Gigaset USB Adapter 300. We generally differentiate between two types of wireless network:
u Infrastructure mode u Ad-hoc mode
Infrastructure mode Infrastructure mode connects wireless and wired networks with one another. In addition to the mobile stations, infrastructure mode needs an access point such as the Gigaset SE366 WLAN. In infrastructure mode, the stations in the network always communicate via this access point. Each station that wants to be part of a wireless network must first be registered with the access point before it can exchange data. The access point establishes the connection between the mobile stations of a wireless network and a wired LAN (Ethernet) or the Internet. This is described as the device's router functionality. The router sends data packets that are not addressed to stations within the network "outside," and forwards data packets originating from "outside" to the appropriate station within the network. You can use the Gigaset SE366 WLAN to connect

Procedure for installation and configuration
1. First install an Ethernet network card or a wireless Network adapter such as the Gigaset PC Card 300 or the Gigaset USB Adapter 300 in the PCs you want to connect to the Gigaset SE366 WLAN. The installation process is described in the user guides for these products. Note: When installing wireless network adapters: The default SSID for the Gigaset SE366 WLAN is ConnectionPoint. 2. Make the necessary connections (PCs, modem) to the Gigaset SE366 WLAN and switch the device on (see the section entitled "Connecting the Gigaset SE366 WLAN" on page 22). 3. Before the PCs can communicate with the Gigaset SE366 WLAN and with each other in a local network, you must change their network settings. This will normally be the case if you are using the Windows default settings. To find out how to do this, read the document entitled Network configuration on the CD-ROM. First connect just one PC to the Gigaset SE366 WLAN. You can then carry out the basic configuration. After that you can connect further PCs. If your clients support WPS, you can establish the link from the PC's wireless network adapter to the Gigaset SE366 WLAN very simply: Push the registration button on the Gigaset SE366 WLAN and activate registration mode on the client. This is described on page 68 and in the user guide for the network adapter. You can also establish connections to other clients manually. 4. Configure the Gigaset SE366 WLAN to activate the device's Internet access (refer to the section entitled "Basic Setup Wizard" on page 31). To do this you will require access data from your Internet service provider. If you want to use the Gigaset SE366 WLAN's other functions, e.g. the comprehensive security features, use the router's Security Setup (see page 35) or the Advanced Settings menu (see page 44).

to have the clock change automatically to summer time and/or to the time zone as you wish.
Configuring Internet connections
You will find the access data you need for configuring the Internet connection in the documentation you receive from your Internet Provider (ISP).
Select your service provider from the Service provider selection menu. If your Internet provider is not included in the list, select Other. The list of Internet service providers offered depends on your choice of country in the Regional Options.
Enter the data you have been given by your Internet provider.
When you choose your Internet provider from the list, most of the data you need is entered by default on the screen. You can also often confirm the defaults for the Other option. Check that the Protocol complies with the data supplied by your Internet provider.
Note: Connection to the Internet is only possible if you have entered all the data of your Internet provider correctly.
Select how Internet sessions are to be established via the Connection mode:
Select Always on if the connection is to remain set up when the Gigaset SE366 WLAN is switched on. Note: If you subscribe to a time-based service, this option can result in high connection charges. Select Connect on demand if applications such as a Web browser or an e-mail program are allowed to connect to the Internet automatically. In the Idle time before disconnect field, enter a period of time after which the Internet connection is to close down automatically if no data is transmitted (default setting: 3 minutes, range: 1 to 99 minutes). This time setting only applies to the Connect on request option. A permanent connection is achieved using the Always on option. Select Connect manually if you always want to establish and end the connection to the Internet manually. If you subscribe to a time-based service this will save you high connection charges. How to establish a connection manually is described on page 82. nect to the Internet. Any existing Internet connection will be closed first.

Activate IGMP proxy server if you wish to use this function.
Configuring the Advanced Settings DNS server
DNS is a decentralised service that assigns PC names or Internet addresses (Domain names) and IP addresses to one another. A DNS server has to administer this information for each server or each LAN with an Internet connection. Normally your Internet provider supplies you with a DNS server, which makes this assignment when the connection to the Internet is set up. If necessary, you can define the DNS server to be used for Internet connections manually.
In the Advanced Settings Internet Internet Connection menu, select the entry

DNS Servers.

Activate the Use custom DNS servers function by selecting On. Enter the IP addresses for your Preferred DNS server and Alternate DNS server. Click OK to apply the settings.

MAC address

If you had Internet access through the same Internet provider before connecting the Gigaset SE366 WLAN, then it is possible that the MAC address of one of your PCs was used for registration when access was configured. In this case, you must either replace the current MAC address with the MAC address registered with the Internet provider or ask your Internet provider to register a new MAC address for your account. Carry out the following steps:
Connect a PC to the Gigaset SE366 WLAN and open the configuration environment. In the Advanced Settings Internet Internet Connection menu, select the entry

MAC address.

Select the MAC address that is to apply to the Internet connection:
Use default device MAC address: You can leave this default setting if the MAC address of the Gigaset SE366 WLAN is used to connect to the Internet. Use MAC address of this PC: Select this option if the MAC address of the currently connected PC was previously registered for connecting to the Internet or if you have re-registered the MAC address of the PC on which you are currently working. Use custom MAC address: Select this option if you have asked your Internet provider to register a new MAC address and this is not the MAC address of the PC on which you are currently carrying out the configuration.

Firewall

The firewall functions of the Gigaset SE366 WLAN include various security functions for your local network. You can:
u protect your network against hacker attacks (see below), u block individual PCs' access to individual services or Internet sites(see page 53).
The firewall functions for the Gigaset SE366 WLAN are activated and configured in the factory. If you wish to deactivate the firewall, carry out the following steps:
In the Advanced Settings Internet menu, select the entry Firewall. Select the required option. Click OK to apply the settings.

Select the channel for transmitting the data.
SSID broadcast If this option is enabled (default setting), the Gigaset SE366 WLAN will send the SSID with all data transmissions and your Gigaset SE366 WLAN's SSID will be displayed on PCs that have a wireless network adapter. In this case, eavesdroppers could use the SSID to gain access to your local network. If you disable SSID broadcast, your Gigaset SE366 WLAN's SSID will not be displayed. This increases protection against unauthorised access to your wireless network. However, you must make a note of the SSID. You will need it to log in to your PC.
Select the Off option to deactivate SSID broadcast.

Sending power

Select the required sending power for your device.
We recommend that you select a sending power with a range to suit the spatial environment of your local network. A range that is much greater makes it easier to eavesdrop on your wireless data transmission. Channel bonding You can only use Channel bonding if this function is supported by at least one client in your wireless network. For the best possible data transfer rates, all clients in your wireless LAN should support Channel bonding.
Select an option for Channel bonding from the list: 20 MHz, 40 MHz or
40/20 MHz Auto (default). Network performance You can optimise network performance in the following ways:

u Optimize throughput

maximises the data transmission rate in your network and ensures that data traffic is transmitted immediately.

u Optimize power saving

optimises power consumption in order to extend standby times for mobile devices in your network, e.g. notebooks, PDAs and WLAN handsets.

u Custom

This allows you to adjust the netwoek performance to suit your needs on the basis of the following items: Beacon interval defines the interval between two Beacons. Measured in milliseconds, default = 100 msecs. DTIM interval defines the interval between two DTIMs for devices in powersaving mode. Measured in number of beacons, default = 2 beacons.
Choose the desired Network performance.
Configuring the Advanced Settings Configuring WPS
Wifi Protected Setup (WPS) makes it easier to establish a wireless network. Devices equipped with WPS are able to create and synchonise an SSID and a WPA key (pre-shared key) automatically. All you need to do to establish a secure wireless connection is press the registration button and click once in the user interface of the client. For further information, see section "WPS" on page 13.

In the Wireless Network menu, choose WPS Registration.
Choose the desired Registration Mode:
Push Button Click OK to start the WPS registration. This function corresponds to pressing the Registration button on the devices back panel. After starting the WPS registration, the device searches for a WPS client in range. Any WPS client in range that activates its WPS function within two minutes gets the Gigaset SE366 WLAN security data (SSID and pre-shared key) and is thereby registered. The registration progress is shown in the window. You can also follow the registration process via the LED display (see page 19). Send own PIN An automatically generated PIN is shown. If you want to create a new PIN, click Generate PIN. Please note that any devices that may be connected with the old PIN no longer have access to the Gigaset SE366 WLAN. Click OK to activate your settings.
Enter the generated PIN on all WLAN partner devices that are to establish a connection. Enter partner device PIN You would only use this option if the PIN of another device is being used in your WLAN. Enter the PIN of the WLAN partner device and click OK to activate your settings. This PIN must be used by all WLAN partners for logging on to the Gigaset SE366 WLAN. Note: If you have activated access control via the MAC address filter, only clients already included in the MAC address list can register via WPS.

Setting encryption

You should activate data encryption to protect your wireless local network against eavesdropping from outside or to prevent unauthorised access to your data. If you send data over wireless channels, we recommend that you activate encryption (WEP or WPA) on your wireless network components. Note: If you have already performed WPS registration, WPA2-PSK/WPA-PSK encryption is activated. The following description is only valid if you are not using WPS.
In the Wireless Network menu, select Encryption.
The following security mechanisms are currently available:
u WPA2-PSK and WPA2-PSK / WPA-PSK (see page 70) u WPA2 and WPA2 / WPA with authentication server (see page 70) u WEP encryption (Wired Equivalent Privacy), (see page 71).
WPA2-PSK and WPA2-PSK / WPA-PSK
Note: If you have already performed WPS registration (see page 13 or page 68), you will see the generated pre-shared key on this screen. You can change the encryption here if you dont want to use WPS. In this case, you also have to configure all wireless network adapters manually. If you performed manual encryption first and then performed WPS registration, the manual encryption data is overwritten. You then have to register all wireless network adapters via WPS or manually re-enter the encryption generated with WPS on the network adapters.

Gigaset SE366 WLAN / englisch / A31008-M1063-R101-3-7619 / glossary.fm / 13.06.2007

Glossary

Access point An access point such as the Gigaset SE366 WLAN is the central element in a wireless local area network (WLAN). It handles connection of the wireless-linked network components and regulates data traffic in the wireless network. The access point also serves as an interface to other networks, e.g. an existing Ethernet LAN or via a modem to the Internet. The network mode for wireless networks with an access point is called Infrastructure mode. Ad-hoc mode Ad-hoc mode describes wireless local networks (WLANs) in which the network components set up a spontaneous network without an Access point, e.g. several notebooks in a conference. All the network components are peers. They must be equipped with a wireless Network adapter. Beacon Beacons are data packets that are sent by devices in a wireless network to all other devices to indicate that they are available and ready to receive. Beacons are also used to synchronise the wireless network. A beacon interval is the period between two beacons in milliseconds. Bridge A bridge connects several network segments to form a joint network, e.g. to build a TCP/ IP network. The segments can have different physical characteristics, e.g. different connections such as Ethernet and wireless LANs. Linking individual segments via bridges makes it possible to build local networks of practically unlimited size. See also: Switch, Hub, Router, Gateway Broadcast A broadcast is a data packet that is not directed to a particular recipient but to all the components in a network. The Gigaset SE366 WLAN does not pass broadcast packets on to the Internet; they always remain within the local area network (LAN) administered by the Gigaset SE366 WLAN. BSSID Basic Service Set ID The BSSID is used for unique differentiation between one wireless network (WLAN) and another. In Infrastructure mode the BSSID is the MAC address of the Access point. In wireless networks in Ad-hoc mode the BSSID is the MAC address of any one of the participants.
Client A client is an application that requests a service from a server. For example, an HTTP client on a PC in a local network requests data, i.e. Web pages, from an HTTP server on the Internet. Frequently the network component (e.g. the PC) on which the client application is running is also called a client. Connect on demand Connect on demand means that applications such as a Web browser, Messenger and Email automatically open an Internet connection when they are launched. This can lead to high charges if you are not using a Flat rate. This function can be deactivated at the Gigaset SE366 WLAN to save call charges. DHCP Dynamic Host Configuration Protocol DHCP handles the automatic assignment of IP addresses to network components. It was developed due to the fact that in large networks especially the Internet defining IP addresses is very complex as participants frequently move, drop out or new ones join. A DHCP server automatically assigns the connected network components (DHCP Clients) Dynamic IP addresses from a defined IP pool range, thus saving a great deal of configuration work. In addition, it also allows address blocks to be used more effectively: Since not all participants are in the network at the same time, the same IP address can be assigned to different network components in succession as and when required. The Gigaset SE366 WLAN includes a DHCP server and can automatically assign IP addresses to PCs in the local network. You can specify that the IP addresses for certain PCs are never changed. DHCP server See DHCP DMZ Demilitarized Zone, see also Exposed Host DMZ describes a part of a network that is outside the Firewall. A DMZ is set up, as it were, between a network you want to protect (e.g. a LAN) and a non-secure network (e.g. the Internet). A DMZ is useful if you want to offer Server services on the Internet which, for security reasons, will not run behind the firewall, or if Internet applications do not function correctly behind a firewall. A DMZ permits unrestricted access from the Internet to only one or a few network components, while the other network components remain secure behind the firewall.

DNS Domain Name System DNS permits the assignment of IP addresses to computers or Domain names, which are easier to remember. A DNS server must administer this information for each LAN with an Internet connection. As soon as a page on the Internet is called up, the browser obtains the corresponding IP address from the DNS server so that it can establish the connection. On the Internet. the assignment of domain names to IP addresses is based on a hierarchical system. A local PC only knows the address of the local name server. This in turn knows all the addresses of the PCs in the local network and the next higher name servers, which again know addresses and the next higher name servers. DNS server See DNS Domain name The domain name is the reference to one or more Web servers on the Internet, e.g. siemens.com. The domain name is mapped to the respective IP address via the DNS service. DoS attack Denial of Service A DoS attack is a particular form of hacker attack directed at computers and networks with a connection to the Internet. The aim is not so much to steal data but to paralyse the computer or network so severely that the network resources are no longer available. A typical hacker attack involves a remote computer claiming that it is acting on behalf of a paralysed computer, for example, and receiving the data intended for you. DSL Digital Subscriber Line DSL is a data transmission technology in which a connection to the Internet can be run over normal telephone lines. A DSL connection is supplied by an Internet Provider. It requires a DSL modem. DTIM Delivery Traffic Indication Message A DTIM is a signal that is sent by an access point as part of a Beacon to a client device in power-saving mode to indicate that a data packet is ready for delivery. The DTIM interval defines the frequency with which a DTIM appears in a series of beacon packets.
DynDNS Dynamic DNS The assignment of Domain names and IP addresses is handled by the Domain Name Service (DNS). This service is now enhanced with so-called Dynamic DNS (DynDNS) for Dynamic IP addresses. This enables the use of a network component with a dynamic IP address as a Server on the Internet. DynDNS ensures that a service can always be addressed on the Internet under the same domain name regardless of the current IP address. Dynamic IP address A dynamic IP address is assigned to a network component automatically by DHCP. This means that the IP address of a network component can change with every login or at certain intervals. See also Static IP address Encryption Encryption protects confidential information against unauthorised access. With an encryption system, data packets can be sent securely over a network. The Gigaset SE366 WLAN offers WEP encryption and WPA encryption for secure data transmission over wireless networks. Ethernet Ethernet is a network technology for local networks (LANs) defined by the IEEE as standard IEEE 802.3. Ethernet uses a baseband cable with a data transmission rate of 10 or 100 Mbps. Exposed Host Exposed Host refers to a PC outside the firewall. See also DMZ Firewall Firewalls are used by network operators as protection against unauthorised external access. This involves a whole bundle of hardware and software actions and technologies that monitor and control the data flow between the private network to be protected and an unprotected network such as the Internet. See also NAT Flat rate A flat rate is a special billing system for Internet connections. The Internet Provider charges a monthly fee regardless of the duration and number of logins. Full duplex Data transmission mode in which data can be sent and received simultaneously. See also Half duplex

Static IP address A static IP address is assigned to a network component manually during network configuration. Unlike a Dynamic IP address, a static IP address never changes. Subnet A subnet divides a network into smaller units. Subnet mask The subnet mask determines how many parts of a network's IP address represent the network address and how many parts represent the PC address. The subnet mask in a network administered by the Gigaset SE366 WLAN is always 255.255.255.0. This means that the first three parts of the IP address form the network address and only the final part is used for the PC address. In this case, the first three parts of the IP address of all network components are therefore always the same. Switch Like a Hub, a switch is an element used to link different network segments or components. Unlike a hub, however, a switch has its own intelligence, which enables it to forward packets only to the subnet or network component for which they are intended. See also Bridge, Hub, Router, Gateway TCP Transmission Control Protocol The TCP Protocol is part of the TCP/IP protocol family. TCP handles data transport between communication partners (applications). TCP is a session-based transmission protocol, i.e. it sets up, monitors and terminates a connection for transporting data. See also UDP TCP/IP Protocol family on which the Internet is based. IP forms the basis for every computer-tocomputer connection. TCP provides applications with a reliable transmission link in the form of a continuous data stream. TCP/IP is the basis on which services such as WWW, Mail and News are built. There are other protocols as well. TKIP The Temporal Key Integrity Protocol (TKIP) is part of the IEEE 802.11i standard and is used to encrypt data in wireless networks. UDP User Datagram Protocol UDP is a Protocol from the TCP/IP protocol family, which handles data transport between two communication partners (applications). Unlike TCP, UDP is a non-session based protocol. It does not establish a static connection. The data packets, so-called datagrams, are sent as a Broadcast. The recipient alone is responsible for making sure the data is received. The sender is not notified about whether or not it is received.
UPnP Universal Plug & Play UPnP technology is used to spontaneously link home or small office networks. Devices that support UPnP carry out their network configuration automatically once they are connected to a network. They also provide their own services or use services of other devices on the network automatically. URL Universal Resource Locator Globally unique address of a domain on the Internet. Virtual server A virtual Server provides a service on the Internet that runs on another network component, not on the server itself. The Gigaset SE366 WLAN can be configured as a virtual server. It will then direct incoming calls for a service via Port Forwarding directly to the appropriate Port of the network component in the local network. WAN Wide Area Network A WAN is a wide area network, which is not restricted to one particular area. The Internet is the most frequently used WAN. A WAN is run by one or more public providers to enable private access. You access the Internet via an Internet Provider. WEP Wired Equivalent Privacy WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmissions in a WLAN against unauthorised access with Encryption of the data transmitted. WLAN Wireless LAN Wireless LANs enable network components to communicate with a network using radio waves as the transport medium. A wireless LAN can be connected as an extension to an existing wired LAN or it can form the basis for a new network. The basic element of a wireless network is the radio cell. This is the area in which wireless communication takes place. A WLAN can be operated in Ad-hoc mode or Infrastructure mode. WLAN is currently specified in the IEEE 802.11 standard. The Gigaset SE366 WLAN hardware complies with standard 802.11n (draft). A software update will be provided when the standard is passed. WPA WPA was developed to improve the security provided by WEP. WPA uses more complex procedures to generate keys, e.g. TKIP (Temporal Key Integrity Protocol). In addition, WPA can use an authentication server (e.g. a RADIUS server) to improve security.
