attachment:Portal/IDB/logo_portal.png Welcome on ["Debian"] Wireless Fidelity


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.

  • ?TableOfContents(3)

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.

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

                                  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.

Using Network Manager

You can also configure wifi using Network Manager. To invoke Network Manager use nm-applet

Check the proper functioning

Resources

  • ["ifconfig"]
  • ["iwconfig"]
  • NdisWrapper - use Windows drivers under Debian/Linux.
