With the user-friendly Pre-Shared-Key method (entering a passphrase of a
length of 8 to 63 signs) the use of 802.11i is easy for everyone. 802.1x and
RADIUS servers can be used in professional infrastructures with a large num-
ber of users.

General rules for WEP keys
When using WEP keys, please pay particular attention to the following general
information:
왘
You have to use exactly matching keys between all involved devices. All
devices use a common key within ad-hoc-networks. In infrastructure net-
works, the key between base station and its radio stations must match .
왘
Different key lengths cannot be used simultaneously on a base station. In
order to giving users with WEP64 devices encrypted access to a base sta-
tion, the encryption for this base station must be set to WEP64.
왘
Wireless LAN interfaces with WEP128 always contain also WEP64, too. At
the same time, WEP128 is downward compatible to WEP64. A WEP128
device will register automatically with the short key at a WEP64 encrypted
base station.
Rules for entering WEP keys
WEP keys can be entered as ASCII characters or in hexadecimal form. The
hexadecimal form begins with the characters '0x'. The keys have a length
depending on the WEP method:
The ASCII character set includes the characters '0' to'9', 'a' to 'z', 'A' to 'Z' and
the following special characters:
! ” # $ % & ´ () * + , - ./ : ; < = > ? @ [ \ ] ^ _ ‘ { | } ~
The HEX form uses the numbers '0' to '9' and the letters 'A' to 'F' to display
each character as a character pair, which is why twice the number of
characters is required to display a HEX key.
