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.

Reboot!

After the installation process completes, you will be prompted to reboot your machine.

It is strongly recommended that you reboot your machine.

After rebooting the Windows “Found New Hardware” utility may appear. Click through the screens to allow the wizard to install the software for the adapter.

If your network does not use DHCP, you will need to configure your adapter with appropriate IP parameters.

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:
