WIRELESS(7)						     Linux Programmer's Manual						       WIRELESS(7)

NAME

       wireless - Wireless Tools and Wireless Extensions

SYNOPSIS

       iwconfig
       iwpriv -a

DESCRIPTION

       The  Wireless  Extensions  is  an API allowing you manipulate Wireless LAN networking interfaces.  It is composed of a variety of tools and
       configuration files. It is documented in more detail in the Linux Wireless LAN Howto.
       The Wireless Tools are used to change the configuration of wireless LAN networking interfaces on the fly, to get their  current	configura-
       tion, to get statistics and diagnose them. They are described in their own man page, see below for references.
       Wireless  configuration	is specific to each Linux distribution. This man page will contain in the future the configuration procedure for a
       few common distributions. For the time being, check the file DISTRIBUTIONS.txt included with the Wireless Tools package.

DEBIAN 3.0
       In Debian 3.0 (and later) you can configure wireless LAN networking devices using the network configuration tool ifupdown(8).

       File : /etc/network/interfaces

       Form : wireless-<function> <value>
	      wireless-essid Home
	      wireless-mode Ad-Hoc

       See also :
	      /etc/network/if-pre-up.d/wireless-tools
	      /usr/share/doc/wireless-tools/README.Debian

SuSE 8.0
       SuSE 8.0 (and later) has integrated wireless configuration in their network scripts.

       Tool : Yast2

       File : /etc/sysconfig/network/wireless
	      /etc/sysconfig/network/ifcfg-*

       Form : WIRELESS_<function>=<value>
	      WIRELESS_ESSID="Home"
	      WIRELESS_MODE=Ad-Hoc

       See also :
	      man ifup
	      info scpm

ORIGINAL PCMCIA SCRIPTS

       If you are using the original configuration scripts from the Pcmcia package, you can use this method.

       File : /etc/pcmcia/wireless.opts

       Form : *,*,*,*)
		  ESSID="Home"
		  MODE="Ad-Hoc"
		  ;;
