A wireless LAN is normally used in a predefined environment. In such a network,
Wireless Ethernet Adapters are mounted at assigned places, each covering its own
area in which wireless nodes can operate. These Wireless Ethernet Adapters are
connected to a wired network to communicate with each other and with servers
and clients on that network.
The 11MBPS Wireless Ethernet Adapter can be connected to a 10 Mbps Ethernet
network through a RJ45 (UTP) connector.

4.6 Security
WEP Enabled: The default setting is Disable. Encryption (WEP)—additional measure
of security on your wireless network which can be achieved by using
WEP (Wired Equivalent Privacy) encryption. When an encrypted
frame is received it will only be accepted if it decrypts correctly. This
happens only if the receiver has the WEP Key used by the
transmitter. All devices on the network, and the Wireless Ethernet
Adapter, must share the same WEP selection – either Enable or Disable
To enable WEP Encryption, click on WEP Enable.
16
WEP Key Length: The default Key Length is 64-bit. The WEP key is generated from
Hexadecimal entries that are either 64 or 128-bit in length. (This is
also sometimes referred to as 40-bit or 104-bit encryption) When
enabling encryption, select the Key Length, either 64 or 128-bit, and
then input the Hexadecimal digits. For 64 bit keys you must
enter 10 hex digits into the key fields, for 128 bit keys you must
enter 26 hex digits. If you leave the key field blank this means a
key of all zeros.
Note: Only the following alphanumeric characters are allowed in the entry, which is 0 to 9,
atof.
WEP Key to Use: Use the pull-down menu to select the WEP key. All devices on the
network must use the same key to communicate with one another.
Deny Unencrypted Data: For additional security when WEP is enabled, select Deny
Unencrypted Data. Data received without a WEP key is
rejected when Deny Unencrypted Data is selected.
Authentication Type. You may choose between Open System, Shared
Key, and Both. The Authentication Type default is set to
Open System. Shared Key is when both the sender and
the recipient share a secret key. All points on your network
must use the same authentication type. It is recommended
that you use the default setting.
