Here are the instructions. Note that it is different depending on whether your wireless device is usb, pci or pcmcia
Mandrake does have hotplug support..
=======================================================================
Configuring:
NOTE: linux-wlan-ng does not fully implement the wireless extensions
interface. This means that you can't use iwconfig and its kin to
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
install:
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.
------------------------------
FOR PCMCIA USERS:
A) Edit /etc/pcmcia/network.opts file to set up your IP settings.
Note: for a station, the SSID you're connecting to will be appended to the
current pcmcia scheme name. You can use this to have different
IP setups for different wireless LANs you connect to (e.g. home vs. work).
Note2: This only applies if you are using a stock pcmcia-cs
package. Most (if not all) distros use their own mechanisms for
configuring pcmcia network interfaces, and thus
/etc/pcmcia/network.opts may not even be present.
B) Restart pcmcia-cs with the command:
/etc/rc.d/init.d/pcmcia restart
C) Insert the card. For most cards, a solid LED indicates that the
SSID you specified was found, a bss was joined, and the firmware
completed the authenticate and associate processes.
D) Run ifconfig and route to determine if your IP and route settings are
listed as you wanted them. It's also a good idea to look at the file
/etc/resolv.conf to see if your nameserver address has been set up
correctly.
------------------------------
FOR PCI, PLX, OR USB USERS:
A) You must make sure that the drivers get loaded at boot time and that the
necessary initialization takes place. The simplest way to do this is
to add the following commands to your rc.local file:
modprobe prism2_pci [or prism2_usb/prism2_plx]
wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng wlan0 lnxreq_autojoin ssid=<your APs SSID> authtype=opensystem
ifconfig wlan0 <yourIP> netmask <yourNetmask> broadcast <yourBroadcast>
route add default gw <yourGateway>
Also, don't forget to set up your resolv.conf to point at your DNS server.
B) Alternatively, you can use the rc.wlan script, which ties into the
/etc/wlan/* configuration files mentioned above.
We currently don't create the softlink from the runlevel directories to
the wlan startup script due to differences in distributions, but the
scripts are redhat-aware, and can be extended to hook into other tools
easily. (patches welcome!) Just make sure it is brought up early in
the process, namely, before the the network interfaces are brought up.
C) Add an alias for wlan0 in /etc/modules.conf. For example, a usb
interface on wlan0 would be set up as:
alias wlan0 prism2_usb
Substitute prism2_plx or prism2_pci as appropriate.
------------------------------
FOR USB USERS:
A) Make sure your kernel usb support is running
B) Plug in the Prism2.x USB device
C) Run 'modprobe prism2_usb prism2_doreset=1' to load the driver into memory.
D) Run 'wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable' to initialize the
driver+MAC functions.
E) Run 'wlanctl-ng wlan0 lnxreq_autojoin ssid=<your ssid> authtype=opensystem'
to enable the MAC in Infrastructure Station mode.
F) Run 'ifconfig wlan0 <your IP address>'
Or, you can use the provided hotplug scripts, if your distribution has
hotplug support.
IMPORTANT: Due to an issue with some versions of the Prism USB firmware,
the driver usually needs to perform a port reset.
Some combinations of usb low-level drivers, kernel releases, and
hardware don't like this, and usually end up generating a kernel OOPS.
newer kernels are much better in this regard. In particular, Intel usb
controllers are the most trouble-prone.
The OOPS is due to bugs in the linux USB core, and newer kernels
(2.4.19 and later) behave much better in this regard.
However, the good news is that primary firmware 1.1.2 seems to resolve
the need for the port reset to begin with. Contact your vendor to
request this update.
Also, using the 'Alt. UHCI' controller driver (uhci.o) is broken with
kernels older than 2.4.22 due to a bug in the controller driver.
