WPS

Wi-Fi Protected Setup (

WPS

) makes it easier to establish and encrypt a wireless net-

work (1 click only). You no longer need to configure and synchronise the individual

components of your wireless network manually

.

A wireless network is assigned a name (

SSID

) and requires the encryption of data traffic

to protect against the risk of unauthorised access. The access point requires authentica-

tion with an SSID and - if encryption is activated - a key to allow a WLAN adapter to

access services.

WPS uses the encryption methods WPA-PSK or WPA2-PSK. Devices with WPS can auto-

matically synchronise each other. During first registration a new SSID is created. The

predefined individual pre-shared key is used for encryption.

WPS is not possible in networks that use WEP encryption or WPA2/WPA authentication.

WPS may be used without encryption.

Clients without WPS can be connected manually.

WPS provides two possibilities for registration:

u

Via registration button

The access point (e.g. the Gigaset SX763 WLAN dsl) has a registration button. The

registration button is available either:

–

as hardware: a specific button (labelled

Scan

) is provided on the device’s back

panel.

–

as software: registration can be started via the

WPS Registration

page of the

user interface.

In the description that follows, the term registration button refers to both the

Scan

button and the corresponding function in the user interface.

Depending on your hardware version, WPS registration may only be possible via the

user interface.

Once the registration button has been activated, the device allows the registration

of a WLAN client (repeater or wireless network adapter) during a two-minute inter-

val.

The first time this button is pressed, the device automatically creates a SSID and a

pre-shared key, if these had not been already set on delivery or has been configured

before manually. If a client activates WPS registration within the two-minute inter-

val, the security data is exchanged and a connection is established. Only

one

client

may synchronise during the two-minute interval. After the successful synchroniza-

tion the registration is closed.

The automatically or manually created security data is valid for all further WPS reg-

istration processes. If you change this security data again manually or after a factory

reset the clients have to be registered again.

u

Via Personal Identification Number (PIN)

The PIN offers improved security for registration. No other device (e.g. in an adjacent

room) can log in unnoticed. A PIN is used for registration which must be identical on

both devices. If a client logs in with this PIN, the security data is synchronised. Usu-

ally the PIN of the access point is used. For security reasons a new PIN can be cre-

ated.

It is also possible to create the PIN on one of the clients.

Further information you will find in chapter "Starting WPS registration and configur-

ing WPS" on page 90.

WLAN adapters without WPS can also be set up manually, i.e. the SSID and key must be

entered manually. How you can find out which SSID and which pre-shared key is set, you

can read in chapter "Configuring wireless connections" on page 87.

WPS cannot be used together with WEP encryption or WPA/WPA2 authentication.

The Gigaset SX763 WLAN dsl

Features and applications

The Gigaset SX763 WLAN dsl's wide range of features makes it ideal for a large number

of applications.

Depending on your device, some of the features may differ from the description in this

instruction manual.

u

Internet access

The Gigaset SX763 WLAN dsl allows several users to have Internet access via the

integrated

ADSL /ADSL2+

modem.

–

Since many DSL providers permit communication with end users via the

PPPoE

protocol, the Gigaset SX763 WLAN dsl has an integrated

Client

for this protocol,

so you no longer have to install this service on your PC.

–

The Gigaset SX763 WLAN dsl supports shared Internet access for

up to 252 users.

This means several users in your network can surf the Internet at the same time,

all using the same Internet account.

u

Setting up a local area network

The Gigaset SX763 WLAN dsl offers the following possibilities:

–

Four devices connected via

Ethernet

ports with a transmission speed of 10 or

100

Mbps

(with automatic recognition).

–

Up to 252 mobile terminals connected via a radio interface with a transmission

speed of up to 108 Mbps. It complies with

IEEE 802.11g

standard and can work

with all products that satisfy Standard IEEE 802.11b or 802.11g. Use of Super G

technology allows for high transmission speed.

–

Using the Gigaset SX763 WLAN dsl makes it easy to set up a network at home or

in small offices. For example, users can exchange data or share resources in the

network, such as a file server or printer. You can connect a USB hard disk or a

printer to the USB interface of the Gigaset SX763 WLAN dsl and make them avail-

able to all users in your network.

The Gigaset SX763 WLAN dsl supports

DHCP

for dynamic IP configuration of the

local area network, and

DNS

for domain name mapping.

u

Connecting phones and Internet telephony

The Gigaset SX763 WLAN dsl permits

–

Internet telephony via the DSL port.

–

Fixed network telephony via the analogue port.

–

Connection of two analogue phones for Internet telephony and for fixed network

calls as well as connection of wireless SIP phones and PCs with SIP clients for

Internet telephony.

–

Connection of an answering machine or fax.

Data transfer for

VoIP

is handled by the

SIP

protocol with high connection and voice

quality. If the Internet connection has been interrupted or you do not want to make

a call via VoIP, you can simply make a call via the fixed network (if a fixed network

phone is connected).

u

Security functions

The Gigaset SX763 WLAN dsl offers comprehensive security measures:

–

Firewall

protection against unauthorised access from the Internet

All PCs in the local area network use the

Public IP address

of the Gigaset SX763

WLAN dsl for their Internet connections, which makes them 'invisible' on the

Internet. The Gigaset SX763 WLAN dsl only allows access from the Internet if this

has been requested from within the local area network.

With the firewall, the Gigaset SX763 WLAN dsl also offers comprehensive protec-

tion against hacker attacks.

–

Service filtering

The Gigaset SX763 WLAN dsl can filter Internet access. Here you determine which

PCs may access which Internet services.

–

Access control and encryption for the local area network

The Gigaset SX763 WLAN dsl is delivered with a predefined individual encryption

(WPA2-PSK/WPA-PSK with pre-shared key). You will find the corresponding infor-

mation at the label on the devices bottom. So, your wirless network is protected

against unauthorised access.

If there are wireless network adapters of your PCs do not support this encryption

method, you can use other encryption methods and authentication methods

(WEP, WPA/WPA2, 802.1x) to prevent unauthorised access to your wireless LAN

or to make data illegible to unauthorised parties.

With MAC access control you can allow wireless access to selected PCs.

u

Offering your own services on the Internet

–

If you want to offer your own services on the Internet, you can set up the Gigaset

SX763 WLAN dsl as a virtual server without permitting further access to the local

area network.

–

DMZ

(Exposed Host)

This allows you to release a PC in your local area network for unlimited access

from the Internet. Note that in this case your local area network will no longer be

adequately protected against Internet attacks.

u

Providing an HTTP or FTP server via USB interface

–

You can easily establish an FTP or an HTTP server for Internet access with the

Gigaset SX763 WLAN dsl.

–

You can connect a USB hub to the USB port on your Gigaset SX763 WLAN dsl and

thereby at the same time provide a printer and a storage medium for all clients in

your local area network.
