Local network configuration

Modern computers running Windows Vista, Windows XP, Windows 2000 or Mac OS X

operating systems are usually already configured on delivery to operate without

difficulty in a wired local network (Ethernet/LAN) or wireless network (WLAN). The

connection to a router or access point is established automatically in this case.

If there is no connection to a Gigaset SE587 WLAN dsl as yet, you may need to adapt the

network settings on the computer.

u

You have to define the network name and the encryption on the computer for a

wireless connection (see page 38).

u

Network addresses (IP addresses) are normally assigned automatically. To change

the default settings of your operating system for assigning IP addresses, you have to

change the TCP/IP settings. You will find further information about this topic in the

Section "IP addresses" after a short introduction. The TCP/IP settings for the various

operating system variants are then described from page 42 onwards.

u

If you are still using Windows 98, you will need to install TCP/IP and set up a network

on the PC if your PC has not been operated previously in a network (see page 52).

IP addresses

Every PC in the network must have a unique network address, referred to as the IP

address, so that it can be accessed by and differentiated from the other components in

the network.

Your Gigaset SE587 WLAN dsl is equipped with a DHCP server, which performs the

addressing in the network independently. This means that the IP addresses are

automatically assigned to the computers (dynamic IP addresses).

Under normal circumstances you therefore do not have to do anything because the

Obtain an IP address automatically

(

Using DHCP

for Mac OS X) option is set when the

network is set up.

It is advisable in some cases, however, to assign static IP addresses, for example if you

wish to run a wireless network in ad-hoc mode or want to make PC services available on

the Internet. In this case, you have to change the network settings of the PCs and

configure static IP addresses.

Note:

You can check whether your PC already has a connection to a router or access point

by simply entering the

ping

command at the command prompt of your Windows

operating system or at the Terminal of your Mac OS X. Please refer to Section

„Checking the connection to the Gigaset SE587 WLAN dsl” on page 63 for further

details.

Information on assigning static IP addresses

You define the private IP addresses for the computers in your local network yourself.

Addresses from an address block reserved for private use should be used. This is the

address block

192.168.0.1 - 192.168.255.254

Example:

PC 1: 192.168.1.2

PC 2: 192.168.1.3 etc.

Computer names and workgroups

When your network is being set up, your computer is assigned a name. This is carried

out when the operating system is installed (with the exception of Windows 98), i.e. your

computer already has a computer name when it is delivered. The computer name is the

name under which your computer is displayed in the network view.

You can change the computer name, if desired.

Windows operating systems

When your network is set up, your PC is assigned to a workgroup. This is carried out

when the operating system is installed (with the exception of Windows 98), i.e. your PC

has already been assigned by default to a standard working group (usually

WORKGROUP). The workgroup includes a number of PCs that belong to a network and

can share common resources, such as printers and files. You can change the workgroup

to which your PC has been assigned.

Please remember:

The IP addresses you can assign also depend on the subnet mask for your network.

The subnet mask used limits the IP addresses that can be assigned as it determines

how many parts of the IP address of a network represent the network number and

how many the computer number.

255.255.255.0 is normally used in a private network as the subnet mask. This means

the first three parts of the IP address form the network number and the final part can

be used for assigning computer numbers. The first three parts of the IP address of all

network components are therefore always the same. In the case of subnet mask

255.255.0.0, the first two address parts would have to be identical.

An example of subnet mask 255.255.255.0 is given below.

For example, this is correct:

Address of access point: 192.168.1.1

Computer 1: 192.168.1.12

Computer 2: 192.168.1.60 ...

This is incorrect:

Address of access point: 192.168.1.1

Computer 1: 192.168.2.2

Computer 2: 192.168.3.3

Setting up a wireless network

A wireless network connection is made using a wireless adapter that must be installed

on your computer. You may first have to connect a wireless adapter to your notebook or

your computer. For example, this can be a Gigaset USB Adapter, a Gigaset USB Stick or a

Gigaset PC Card, but also a different IEEE 802.11n, 802.11g or 802.11b-compatible

wireless adapter. If you are using this type of wireless adapter, you can set up the

connection to the wireless network using the relevant software. Instructions for this can

be found in the user manual for your wireless adapter.

Most modern notebooks already have a wireless adapter fitted when delivered. In this

case, you should use the tools provided by the operating system to connect the PC,

notebook or Mac to the wireless network.

We explain below how to connect a PC or notebook to a wireless network using

Windows XP SP2, Windows Vista and Mac OS X.

To set up the connection, you need the network name (SSID) of your wireless network

and the key defined on the Gigaset SE587 WLAN dsl for encrypting wireless data traffic.

Carry out the following steps:

ì

Start your notebook or your computer. Make sure your wireless adapter is switched

on. Notebooks generally have a switch for this purpose as well as an LED as a

function display.

Windows XP

If Windows XP receives signals of wireless networks in the current

environment this will be indicated by the symbol for the wireless network

connection in the status area of the taskbar.

ì

Right-click the icon in this case and choose the

Show available wireless networks

option.

If the icon for the wireless network connection is not displayed, you could also proceed

as follows:

ì

Choose

Start

-

Control Panel

-

Network Connections

-

Wireless Network

Connections

Or

ì

Double-click the

Network Environment

icon on the desktop.

ì

Click

Show network connections

in the column on the left.

ì

Double-click the

Wireless Network Connections

icon.

The list of available and visible wireless networks (WLANs) is displayed (see page 39).

Note:

The preset SSID and WPA key are shown on the label on the bottom of the device.

Windows Vista

ì

Click the network symbol in the status area of the taskbar to display the

wireless networks in the current environment.

ì

Click

Connect or disconnect

.

A list of all available wired and wireless networks (WLANs) is displayed (see page 39).

Network list

All wireless networks that can be seen at the current location appear in the network list.

If the SSIDs of the wireless networks are set to invisible they are not displayed.

Windows shows the status of each wireless network graphically and provides

information on the signal strength, the network name and whether security settings

were made for the respective network.

An example for Windows Vista is given below.

Note:

The automatic wireless configuration service must be started so that Windows can

display and manage wireless networks. If nothing is displayed on your PC despite

there being wireless networks within range, check whether the service is started and

start it if necessary.

Windows Vista:

ì

Click

Start

–

Control Panel

–

System and Maintenance

–

Administrative Tools

.

ì

Double-click

Services

.

ì

Check whether the

Automatic WLAN Configuration

service is started and start

it if necessary by clicking

Start

in the column on the left.

Windows XP:

ì

Click

Start

-

Control Panel

.

ì

Click
