Before you begin
Things you should know
BCM94306CB network
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 BCM94306CB internal 802.11g Cardbus 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. Instructions for configuring a network profile are provided in Completing the
setup.
WEP is a security protocol for wireless local area networks (defined in the IEEE 802.11g standard) 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 BCM94306CB network
The Broadcom BCM94306CB solution allows you to make a wireless connection to a network, as illustrated below.

Setting up an ad hoc (peer-to-peer) group network for connecting to the
Internet
To connect the computers in an an-hoc group network to the Internet, you must install the Windows Internet connection sharing (ICS)
component. ICS installation is not required, however, for communication among a group of computers that have a Broadcom
BCM94306CB Cardbus card installed in each computer. You must also add an ad hoc network to the Preferred networks list on the
Wireless Networks tab of the Wireless Configuration box that appears when the BCM94306CB wireless utility is open.
Select one of your desktop computers to serve as the host computer (all other computers are called clients). The host computer must
be running either the Windows 2000 or Windows XP operating system. The host computer is the only computer that connects directly to
the Internet. Broadcom recommends that the host computer be the desktop computer having the fastest microprocessor and the most
memory.
NOTE—Internet connection sharing requires that the host computer have either a modem or another network adapter in addition to a
wireless network adapter. The modem or the additional network adapter is used to access the Internet. Your Broadcom BCM94306CB
Cardbus card is used to share the Internet connections with other clients.
Setting up Internet connection sharing (ICS) on the host computer
To set up ICS in the Windows XP environment
1. Connect the host computer to the Internet.
2. From the host computer, click the Start button.

Cannot connect to the network
If your Broadcom BCM94306CB wireless device appears to be functioning properly but you cannot connect to the network, the problem
may be that there is a mismatch between the Network name (SSID) and Wireless network key (WEP) settings in your Wireless
Network Properties and the name and WEP key of the network you are trying to connect to. As explained in Completing the setup, the
network name and WEP key are case sensitive. Verify that the spelling and case of these parameters are correct and that the settings
are exactly the same on all computers on the network.
If you have verified that the spelling and case of these parameters are correct and that the settings are exactly the same on all
computers on the network and you are still unable to connect to the network, see Performance and connectivity problems.

Data transfer is sometimes
very slow.
Microwave ovens and some cordless phones operate at the same radio frequency as the
BCM94306CB Cardbus cards. When the microwave oven or cordless phone is in use, it interferes
with the wireless network. Therefore, keep computers having the BCM94306CB Cardbus card at
least 20 feet away from your microwave oven and any cordless telephone that operates at a
frequency of 2.4 GHz.
Data transfer is always very
slow.
Some homes and most offices are steel-framed structures. The steel in such buildings may
interfere with your network's radio signals, thus causing a slowdown in the data transmission rate.
Try moving your computers to different locations in the building to see if performance improves.
Computers are not
communicating with the
network.
If your network has an AP1100 access point, check all cables and make sure the power LED on the
front of the AP1100 is green.
In Microsoft® Windows® 2000,
I get the following error
message: Medium cable
disconnected. Also, there is a
red X on my network icon in
the system tray.
This indicates that your computer is not properly configured to connect to the network. Verify that
all of the wireless network properties settings are correct (see Viewing or modifying the wireless
network properties). Also, make sure that your computer is receiving a good signal from the access
point. See Viewing the link status of your wireless connection.
Network performance is really
slow when the system is
docked to a docking station
that has an active Ethernet
port. NOTE—For Windows
2000 only.
This condition occurs if you dock your system into a docking station that has an active Ethernet port
while your Broadcom BCM94306CB internal Cardbus card is still active and connected to an
access point. This happens because Windows 2000 must now handle two active network
connections. You need to either disconnect the Ethernet cable from your docking station, or
disable the radio on your Cardbus Card. To disable the radio on your Cardbus Card, right click on
the Broadcom BCM94306CB utility icon icon in the system tray and click Disable Radio.
NOTE—The radio is not automatically enabled when you computer next starts. To enable the radio,
right-click on the Broadcom BCM94306CB wireless utility icon and click Enable Radio.
