in the config file.

set things up. Instead, read on!
|
||||
|
||||
As of linux-wlan-ng 0.1.16-pre5, the configuration and launch scripts have
|
||||
been largely re-written. pcmcia/rc/hotplug now all use a common library
|
||||
of routines and use the same set of configuration files.
|
||||
|
||||
Now, everything relevant exists in /etc/wlan/*
|
||||
|
||||
/etc/wlan/wlan.conf:
|
||||
|
||||
This file maps between wlan devices and network IDs, and contains
|
||||
the names of all devices that should be initialized by the hotplug
|
||||
and rc scripts.
|
||||
|
||||
/etc/wlan/wlancfg-*
|
||||
|
||||
These files are per-network configurations. This makes it easy to
|
||||
switch between different SSIDs and the various settings they may
|
||||
require, like WEP keys and whatnot.
|
||||
|
||||
The bare minimum you need to do to configure your system after a fresh driver

0) Nothing whatsoever. out-of-the-box, the driver will attempt to associate

with any access point within range.

||||
|
||||
However, we highly recommend setting up a configuration specifically for
|
||||
your network, using the following method:

0) This example assumes your network name/SSID is "MyHomeNetwork"
|
||||
1) cp /etc/wlan/wlancfg-DEFAULT /etc/wlan/wlancfg-MyHomeNetwork
|
||||
2) edit /etc/wlan/wlan.conf and change the SSID_wlan0 line to:
|
||||
SSID_wlan0="MyHomeNetwork"
|
||||
3) edit /etc/wlan/wlancfg-MyHomeNetwork, and make any necessary changes
|
||||
necessary to support your network, such as WEP and whatnot.

A) Edit the /etc/pcmcia/wlan-ng.opts file to configure. These options are

B) Alternatively you can try out the rc.wlan and wlan.conf scripts.
|

They do work, and they are installed into your */init.d directory
|

and /etc directory. We don't currently create the soft-link from

the runlevel directory to the wlan startup script because the

distributions vary too much in this respect. You'll need to create

the soft-link yourself. Just make sure it is early in the process,

namely, before the the network interfaces are brought up. The

actual setup of the SSID and such is in the file /etc/wlan.conf.

Note that you'll also need to add an modules.conf alias statement
|

for the driver that you wish to load (pci or plx), we don't

explicitly load a module in init.d/wlan because we don't know which

one you want. ;-)

/etc/wlan/* configuration files mentioned above.

We currently don't create the softlink from the runlevel directories to

easily. (patches welcome!) Just make sure it is brought up early in
