Configuring Advanced Settings

We recommend that you use an address from a block that is reserved for private use.

This address block is 10.0.0.1 to 10.255.255.254.

ì

Adjust the

Subnet mask

if necessary.

The

Subnet mask

specifies how many address parts of the IP address must be iden-

tical for all network components (including routers).

Configuring the DHCP server

The Giga762SX WLAN dsl has a

DHCP server

for which the factory setting is active. Con-

sequently, the IP addresses of the PCs are automatically assigned by the Giga762SX

WLAN dsl.

ì

To activate the DHCP server, select

On

.

ì

If the DHCP server is active, you can define a

Lease time

. The least time indicates

how long the client may use the allocated IP configuration.

ì

Define the range of IP addresses the Giga762SX WLAN dsl should use to automati-

cally assign IP addresses to the PCs. Define the

First issued IP address

and the

Last

issued IP address

.

ì

If you want to define a different

Default gateway

in your local area network instead

of the Giga762SX WLAN dsl, enter the IP address of this default gateways in the rel-

evant boxes.

Entering the 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 must administer this information for each server or for each

LAN with an Internet connection.

Notes:

New settings can only be made after the Giga762SX WLAN dsl has been rebooted. If

necessary, reconfigure the IP address on your PC (including one that is statically

assigned) so that it matches the new configuration.

Note:

u

If the DHCP server for the Giga762SX WLAN dsl is activated, you can configure the

network setting on the PC so that the option

Obtain an IP address automatically

is set up. For further information, refer to the section entitled "Configuring the

local area network" on the CD-ROM.

u

If you deactivate the DHCP server, you will have to assign a static IP address for the

PCs that use the network settings.

Note:

If you select

Never expires

, the IP addresses are never changed. Activate this

option if you want to make NAT or firewall settings using the IP addresses of the

PCs; otherwise you have to assign static IP addresses to these PCs.

84

Configuring Advanced Settings

Your Internet service provider will usually provide you with a

DNS server

that makes this

assignment when an Internet connection is set up. If necessary, you can manually

define the DNS server to be used for the Internet connections.

ì

Enter the IP addresses for your preferred DNS servers (

Preferred DNS server

and

Alternate DNS server

).

ì

You can define the name of a domain (Windows workgroup) in the

Domain name

field.

Assigning static IP addresses to individual PCs

Even if you have activated the DHCP server, you can still assign a static IP address to indi-

vidual PCs (e.g. when setting up these PCs for NAT functions).

ì

Enter the

MAC address

of the PC to which you want to assign a static IP address.

ì

Enter the

IP address

you wish to assign to the PC.

ì

Click the

Add

button to add the entry to the list.

Configuring wireless connections

If you have implemented wireless PC communication via the Giga762SX WLAN dsl, you

should improve the security of your wireless network via the

Advanced Settings

–

Wireless Network

menu. You can carry out the following functions:

ì

In the

Advanced Settings

menu, select:

Wireless Network

ì

Select

On

for the

Wireless Network

(default setting).

Devices can only log in wirelessly if the WLAN module of the Giga762SX WLAN dsl is

activated.

You can now make the settings for the wireless network.

Wireless Network

Activate the wireless module of the Giga762SX WLAN dsl

and specify basic settings for your wireless network, for

example

SSID, Transmission mode

or

Sending power

.

WPS Registration

Start WPS registration and configure WPS (see page 87).

Encryption &

Authentication

Set up

Encryption

for wireless transmissions (page 87).

Allowed Clients

Restrict access to the LAN of the Giga762SX WLAN dsl

(page 95).

Repeater (WDS)

Activate the repeater function (Wireless Distribution

System,

WDS

) and define repeaters to increase the range of

your WLAN (see page 96).

86

Configuring Advanced Settings

Channel

All clients in the network use the set radio channel for wireless data transfer. You can

choose between various channels, depending on your current location.

ì

Select

Automatic

so that the best channel for transmitting the data is used automat-

ically.

SSID

For the wireless network components to be able to communicate with one another, you

must use the same

SSID

(Service Set Identifier).

The default SSID for the Giga762SX WLAN dsl is shown at the label on the bottom of the

device. For security reasons you can change this SSID and deactivate SSID broadcast (for

information see below).

Enter a character string of your choice. The SSID is case-sensitive. It can contain up to

32 characters. Use a combination of letters, digits and special characters.

SSID broadcast

If this option is enabled (default setting), the Giga762SX WLAN dsl will send the SSID in

all data transfers and the SSID of the Giga762SX WLAN dsl will be displayed on PCs that

have a wireless network adapter. In this case, hackers could use the SSID to detect your

network.

If you deactivate

SSID broadcast

, the SSID of the Giga762SX WLAN dsl will not be dis-

played. This increases protection against unauthorised access to your wireless network.

Make a note of the SSID. You will need it to log on to the PC.

To protect your wireless network, you should also enable encryption of data transmis-

sions (page 87).

ì

Select

Off

to deactivate

SSID broadcast

.

Transmission mode

The IEEE 802.11g standard permits data transfer up to 54 Mbit/s, and the IEEE 802.11b

standard up to 11 Mbit/s. Choose

IEEE 802.11g only

to ensure the best possible data

transfer rates in your network. To operate clients with older wireless network adapters

in your network, select

IEEE 802.11b/g (mixed)

.

ì

Select the required transmission mode for your wireless network.

Note:

If a WPS registration (see page 48) was performed before manual configuration, you

should not change this SSID here manually. Otherwise, the registered clients will no

longer have access to your wireless network.

Note:

The connection to the wireless network adapters will be interrupted until you have

entered the new SSID in them as well.

Configuring Advanced Settings

Sending power

ì

Select the required sending power for your device.

It is recommended that you select a sending power with a range to suit the spatial

environment of your local network. A much greater range makes it easier to eaves-

drop on your wireless data transfer.

ì

Click

OK

to apply the settings.

Starting WPS registration and configuring WPS

Wi-Fi Protected Setup (WPS) makes it easier to establish a wireless network. Devices

equipped with WPS can synchronise the SSID and the WPA key (pre-shared key).

The most simple method to establish a secure wireless connection is press the registra-

tion (Scan) button or click once in the user interface of the Giga762SX WLAN dsl and do

the same with the client. For further information, see "WPS" on page 15.

The configuration program of the Giga762SX WLAN dsl provides beside the

Push But-

ton

method for WPS registration for more security the registrations mode via PIN.

ì

In the

Advanced Settings

menu select:

Wireless Network

–

WPS Registration

ì

Choose the desired

Registration Mode

:

–

Push Button

Click

OK

to start the WPS registration.

This function corresponds to pressing the

Scan

button on the

device’s back panel, if available.

Once WPS registration is activated, the device searches for a

WPS client within range. Any WPS client within range that acti-

vates the WPS function during the two-minute interval
