Introduction: Broadcom BCM94321CB2Cardbus Card User's Guide

Before you begin

Things you should know

BCM94321CB2network

Before you begin

Obtain the following information from your network administrator (if you are a home user, obtain this information from the person that

installed your wireless access point):

●Network names (SSID) of the specific wireless networks that you want to connect to.

●WEP (Wired Equivalent Privacy) key information (if any) for the networks you want to connect to.

●For Microsoft® Windows® networking, your customer name and workgroup name.

●For your network account, your user name and password.

●Your IP address (if not using a DHCP server)

Things you should know

When you start your computer, your Broadcom BCM94321CB2Cardbus card detects certain wireless networks that are

within range. Before you can connect to these and other wireless networks, you must configure a profile for each network using the

information you obtained from your network administrator.

WEP is a security protocol for wireless local area networks (defined in the IEEE 802.11gstandard) that encrypts data sent over radio

waves. The use of the WEP key is optional and can be enabled or disabled. If the network you are connecting to has enabled WEP, you

must also enable WEP in the network profile and set the WEP key to match the WEP key used by the network. Otherwise, you cannot

connect to the network.

Broadcom BCM94321CB2 network

The Broadcom BCM94321CB2solution allows you to make a wireless connection to a network, as illustrated below.
