WEP
WEP (Wired Equivalency Protocol) was the first scheme to provide security for 802.11 communications.
Although since its release it has been determined to contain serious weaknesses, WEP remains an
effective means to prevent casual eavesdropping.
WEP settings are made network-wide; all BreadCrumb devices and wireless clients must agree on a
WEP key in order to establish and maintain communications.
To enable WEP on a BCWN, make sure that all of the BreadCrumbs to configure are visible in
BCAdmin. Then choose
Security , then WEP Settings to display the following window:

A 40-bit or 104-bit hexadecimal key is specified in this field. If this field is left blank, WEP can be
enabled using a previously configured key.
Access Control Lists (ACLs)
A BCWN may be configured with a network-wide Access Control List (ACL) to specify a list of devices
to allow or disallow on the network. Each device communicating on the network (e.g., each BreadCrumb
radio or laptop radio card) has a unique identifier known as a MAC address. ACLs consist of lists of
these addresses to specify permitted or forbidden devices.
When enabled, the ACL may be in two modes: Deny by Default and Allow by Default. In Deny by
Default mode, client devices and BreadCrumb devices are not permitted on the network unless they are
