3.2.3.1 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.
First select whether you want to use 64 bit or 128
bit encryption. 128 bit encryption offers greater
security. Then select either Hex (characters
from 0-9 and a-f) or ASCII (any character) for the
Key Format
. This also determines the length of the
key.
Default Tx Key
allows you to select one of four
preset keys. Select
Key 1
, for example, and enter
your key of choice with the required length.
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

to save your settings. You must then
restart the router for the settings to take effect. To
do so, click
Apply
in the next window. The wireless
network with encryption is available after you restart.
3.2.3.2 WPA/WPA2 Encryption
Wi-Fi Protected Access
(WPA)
is an encrypti-
on method for WLAN. WPA contains the WEP
architecture, but offers additional protection via
dynamic codes, which are based on the Temporal
Key Integrity Protocol (TKIP), and also offers pre-
shared keys (PSK) or extensible authentication
protocol (EAP) for user authentication. However,
a radius server is required for this. WPA2 is a de-
velopment of WPA and uses a different encryption
algorithm, advanced encryption standard (AES).
Select
WPA Pre-shared Key
under Encryption.
Then, under WPA Unicast Cipher Suite, select
WPA (TKIP) or WPA2 (AES).
Then you must select the
Pre-shared Key Format.
Select either
Pass phrase
for a key with a length
of at least 8 and max. 63 characters, whereby
letters (A-Z), numbers and punctuation marks can
be used, or
Hex
for a 64 character key, in which
only numbers from 0-9 and letters from a-f can be
used. The next step is entering a key, called
a
pre-shared-key
(PSK). All clients which are to access the access point must know this character string.
