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)
module-assistant (tool to make optional module package creation easier).
wpasupplicant, client support for ["WPA"] and WPA2 networks (provides 'wpa-' options to /etc/network/interfaces)
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"]

Setting your WiFi device
Identify your network
- Network Name
- Parameter security
- ["WPA"]
- Mode: Access Point / ad-hoc
Configure Interface: AP mode
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 :
# WiFi card section auto eth0 iface eth0 inet dhcp wpa-essid WANADOO-1418 wpa-psk "xxxxxxxxxxxxxxxxxxxxx"
See also /usr/share/doc/wireless-tools/README.Debian and [http://svn.debian.org/wsvn/pkg-wpa/wpasupplicant/trunk/debian/README.modes?op=file&rev=0&sc=0 README.Modes] (["WPA"]) for other examples.
Configure Interface: Ad-hoc mode
You haven't Acces Point, and you want connect 2 PC directly. Image 2 PC: calling hostA et hostB.
Wifi: Configure Wifi on your 2 PC:
iwconfig ath0 mode Ad-hoc iwconfig ath0 essid MYNETWORK
Control on your 2 PC:
iwlist ath0 scanning ath0 Scan completed : Cell 01 - Address: 02:0F:B5:4F:74:ED ESSID:"MYNETWORK" Mode:Ad-Hoc Frequency:2.412 GHz (Channel 1) Quality=42/70 Signal level=-53 dBm Noise level=-95 dBm Encryption key:off Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s 48 Mb/s; 54 Mb/s Extra:bcn_int=100
IP: Configure IP on your hostA
ifconfig ath0 192.168.1.1 netmask 255.255.255.0
Configure IP on your hostB
ifconfig ath0 192.168.1.2 netmask 255.255.255.0
Control on your hostB:
ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. 64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.073 ms 64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=0.061 ms 64 bytes from 192.168.1.1: icmp_seq=3 ttl=64 time=0.062 ms 64 bytes from 192.168.1.1: icmp_seq=4 ttl=64 time=0.063 ms --- 192.168.1.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3001ms rtt min/avg/max/mdev = 0.061/0.064/0.073/0.010 ms
