Client Adapter Installation
 Adapter card should be installed before drivers and
utilities.
 CardBus adapter is keyed and can only be inserted on
way.
 Configuration profiles for CardBus cards are tied to the
slot. Always insert the card into the same slot.
 PCI card adapters should be installed with the PC
power off.
 If the Windows “Found New Hardware Wizard”
appears, click Cancel. Software for the card will be
installed in the next step.

Activity
 Learn how to share an Ethernet-based Internet connection with
wireless computers using an ad hoc wireless network.
 The Internet Connection Sharing (ICS) feature of Microsoft®
Windows® XP allows you to share a single Internet connection
with multiple computers. Built-in support for IEEE 802.11 wireless
LANs (WLANs) allows you to create an ad hoc wireless network.
These two features can be used together to share a wired Internet
connection.
 This article describes how to quickly and easily use Windows XP to
share a wired Internet connection with other WLAN computers:
