Learn how to install a Wi-Fi adapter in your PC.

Install a PCI card in each desktop system you want to connect to your network.
A Wi-Fi adapter connects your computer to the network. If your computer doesn’t already have the adapter that you need built in, you can add one.

Tip: If you’re lucky enough to have a notebook with built-in Wi-Fi, you won’t need the PC Card adapter.

Install the Wi-Fi adapter in each system that will connect wirelessly to the router. If you’re using the D-Link PC Card and PCI adapters, install the software from the CD before installing the hardware, then shut down your system, install the adapter, and reboot. After Windows boots, the Found New Hardware wizard should appear and initiate the driver installation. Select “Install the software automatically” and click Next. If you see a message warning that the driver has not passed Windows logo testing, click Continue Anyway.
