Select
Ad-hoc
under network type. This mode allows you to connect to other wireless LAN client devices, e.g. USB sticks, PCI cards
or cardbus.
The settings for
TX Power, Preamble, RTS Threshold
and
Fragment Threshold
can be left at the default settings. You must also set the
wireless LAN channel used under
Channel
. In Europe, there are 13 channels in the 2.4 GHz frequency range.
If your network uses encryption, switch to the
Authentication and Security
tab and continue confi guration under
Setting wireless
LAN encryption.
If your network is not encrypted, click
OK
to accept the settings. To activate the profi le created, switch to the
Profi les
tab, select the
profi le and then click
Activate
.
3.2.2 Setting the wireless LAN encryption
First, it is important to understand a range of terms. The next section will explain the main terms used here:
Authentication:
Authentication is a process in which the identity, e.g. of a person is determined based on a certain characteristic.
This can be done by fi ngerprint, password or any other proof of authorisation.
Encryption:
Encryption is a process in which a plain text is transformed into a coded text via an encryption process (algorithm). One or
more codes can be used for this.
It must also be mentioned that each individual encryption process offers one or more authentication options.
Please switch to the
Authentication and Security
tab.
This device can be used with the following encryption types:
64 and 128 bit WEP encryption WPA and WPA2 encryption
Note!!! Encryption is deactivated by default. However, for security reasons,
we recommend that you always use encryption.
3.2.2.1 WEP encryption
Wired Equivalent Privacy
(WEP)
is a standard encryption algorithm for WLAN. It both controls the access to the network and guaran-
tees the integrity of the data. This method is considered vulnerable due to a range of weaknesses.
If you want to use WEP encryption, select
WEP
under encryption.
Two options are available for the Authentication type under WEP.
Select
Open
if all clients are to be enabled for WLAN. Now there is virtually no
other authentication.
Select
Shared
if you want to use authentication with the challenge response
process. A shared code is used for authentication in this method. All WLAN users must know this code.
All other selection options under Authentication type are meaningless under WEP.
You can now store four codes in the lower section of the window. The selected code is always used. 64 bit or 128 bit encryption is
supported. 128 bit encryption is more secure. First select whether you want to use
Hex
(allows characters from 0-9 and a-f to be used)
or
ASCII
characters (You can use any characters). The setting and the selection of either 64 or 128 bit encryption determines the
length of the code to be entered.
WEP 64 bit ASCII requires 5 characters
WEP 64 bit HEX requires 10 characters
WEP 128 bit ASCII requires 13 characters
WEP 128 bit HEX requires 26 characters
Examples: 64 bit Hex (10 characters) = 231074a6ef
64 bit ASCII (5 characters) = j31n.
128 bit Hex (26 characters) = 231074a6b9773ce43f91a5bef3
128 bit ASCII (13 characters) = urla0
