attachment:Portal/IDB/icon-wifi-32x32.png This portal deals with the hardware installation of Wi-Fi cards in general. The installation of a card is essentially two steps that are installing the driver (also called the driver or module), and setting up your WiFi network.

Be aware that a WiFi base are operating on an electronic chip called Chipset. We can find the same chip in several different cards. Consequently, the pilot manages this chipset will be the same for all these cards Wifi.

A WiFi interface is an Ethernet interface that also gives access to the configuration parameters peculiar to the Wi-Fi. These parameters are controlled using the ["iwconfig"] program.

Tools prerequisites

wireless-tools, tools for manipulating Linux Wireless Extensions (installed by default on Desktop & Laptop installation)
For system with GUI: NetworkManager (installed by default on Gnome-Desktop & Laptop installation)
wpasupplicant, client support for ["WPA"] and WPA2 networks

Install Driver

Before you buy, you would check the list of hardware with Linux driver (or check for the Linux logo in the box of the WiFi card).

This section presents a list of WiFi cards sorted by manufacturer. It will show you the documentation page of the chip and thus its pilot. We recommend that you retrieve information identifying material.

This list consists of two elements: the device name and the hardware ID. The list is categorized alphabetically by the manufacturer's name and the name of your card.

See [http://cateee.net/lkddb/ the Linux Kernel Driver DataBase] for hardware and protocols know by the Linux ["Kernel"]

NetworkManager is a user-friendly program to control network interfaces. It's especially useful for WiFi. (it's available for ["Gnome"] and ["KDE"]).

Otherwise, you can use /etc/network/interfaces. here's a sample fragment of :
