Wireless Tools-29
Introduction to Wireless Tools
The Wireless Extension (WE) is a generic API in the Linux kernel
allowing a driver to expose configuration and statistics specific
to common Wireless LANs to user space. A single set of tools can
support all the variations of Wireless LANs, regardless of their
type as long as the driver supports Wireless Extensions. WE
parameters may also be changed on the fly without restarting the
driver (or Linux).
The Wireless Tools (WT) package is
a set of tools allowing manipulation of the Wireless Extensions.
They use a textual interface to support the full Wireless
Extension.
This package is known to build and work properly using an LFS-8.4
platform.

Kernel
Configuration
To use Wireless Tools, the kernel
must have the appropriate drivers and other support available. The
appropriate bus must also be available. For many laptops, the
PCMCIA bus (CONFIG_PCCARD) needs to be built. In some cases, this
bus support will also need to be built for embedded wireless cards.
The appropriate bridge support also needs to be built. For many
modern laptops, the CardBus host bridge (CONFIG_YENTA) will be
needed.
In addition to the bus, the actual driver for the specific wireless
card must also be available. There are many wireless cards and they
don't all work with Linux. The first place to look for card support
is the kernel. The drivers are located in Device Drivers →
Network Device Support → Wireless LAN (non-hamradio). There
are also external drivers available for some very common cards. For
more information, look at the user notes.
After the correct drivers are loaded, the interface will appear in
/proc/net/wireless.
Installation of Wireless Tools
First, apply a patch that fixes a problem when numerous networks
are available:
patch -Np1 -i ../wireless_tools-29-fix_iwlist_scanning-1.patch
To install Wireless Tools, use the
following commands:
make
