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.
Now switch to the
Advanced
tab.
Wireless mode allows you to set the standard to be used. This depends on the other devices used in your network. You can choose
either
802.11 B only
mode (11 Mbps): Then this standard only is used; or
802.11 B/G mixed
mode up to 54 Mbps): Both standards are
then supported; If you are not sure which of the standards your devices support, you should use the mixed mode
(802.11 B/G mixed
mode)
. Make all other settings as shown in the image below.

This device can be used with the following encryption types:
64 and 128 bit WEP encryption
WPA Encryption
Note!!! Encryption is deactivated by default.
However, for security reasons, we
recommend that you always use encryption.
9.2.2.1 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 the following settings:
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
Hexadecimal
(allows characters from 0-9 and
a-f to be used) or
ASCII
(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 hexadecimal requires 10 characters
WEP 128 bit ASCII requires 13 characters
WEP 128 bit hexadecimal requires 26 characters
Examples: 64 bit hexadecimal (10 characters) = 231074a6ef
64 bit ASCII (5 characters) = j31n.
128 bit hexadecimal (26 characters) = 231074a6b9773ce43f91a5bef3
128 bit ASCII (13 characters) = urla0
