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"
