Removing the pkg is the simplest way to get rid of it, else check pkg's
docs to learn how to configure/disable it.

check 'wpa_supplicant --help' for drivers wpa_supp understands; however,
wext should be the safe choice on recente kernels.

I have somewhat moved forward... I mean that I have read quite a bit of
doc here and there, and I know a little more about wifi. However,
nothing works still, and I now wonder if I can get this to work.
If I am not mistaking, the reason why I can't wirelessly connect to my
DSL box is that I don't provide the appropriate password : the pasword
that I send is a wpa pasword, and hostap does not support wpa as is ; it
may support wpa when associated with wpa_supplicant with an appropriate
config file, AND a running daemon 'hostapd'. Besides my DSL box, I don't
have any other network that I could test and try to connect to : I can
see three other networks that appear during scanning, but they are also
encrypted. I could try to change the settings of my DSL box so as to set
it for WEP paswords, but I am not keen to do that, even for a test : I
bet it would work, but then it is not my purpose to have that DSL box
WEP encrypted. I intend to be able to occasionnally connect to WEP
encrypted Access Points when travelling, but none of that at home. In
any case, if I can't connect my laptop to my DSL box at home using WPA
encryption, my pcmcia wifi card will be of no use, except maybe 5 or 6
times a year during travels.
According to what I have read, the 'orinoco' driver that is supposed to
also work for my 'intersil prism2' pcmcia card, does not support WPA.
Before I learnt that, I did try to remove 'hostap'. I tried several
times, with no success. I have removed the 'hostap-utils' packages
(apt-get remove hostap-utils). This removal seemed to have worked all
right. But then, once the pcmcia card was introduced into its slot, the
hostpad and hostpad_cs modules came back into action, with exactly the
same results as previously. I believe that the internal firmware of the
wifi card does download a few hostap files onto my system. Still, the
latter said, whenever queryed, that the 'hostap-utils' package was not
installed. Then I thought that I had better install it properly again,
and see if that made a difference : the package got newly installed all
right, but there was no difference in the behaviour of my pcmcia wifi
card. As soon as you introduce that card in its slot, dmesg and other
reports tell you that hostpad driver has been started, whether or not
the debian package is installed. Later on, I realized that I could have
tried to change files in /etc/pcmcia/ : config, config.opts,
hostap_cs.conf, so as to bind my intersil card to orinoco, but, by then,
I had realized that in any case this was not wpa compatible, so I didn't
bother.
So, now, I have read some more doc about wpa_supplicant. I have written
an /etc/wpa_supplicant.config file, a very simple one for a test :
begin copy/paste
**************************************
ctrl_interface=/var/run/wpa_supplicant

}
### Associate with any open access point
### Scans/ESSID changes can be done with wpa_cli
network={
key_mgmt=WPA-PSK
}
**********************************************
end copy/paste
From there on, I tried a wpa_supplicant command as suggested in one of
the readme files or man pages so as to test the system and debug :
#wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
Here is what I got. At first, a copy/paste of what bears the most
important information : Driver does not support WPA !

I must point out that, in any case, the conditions for the support of
wpa encryption were not met : it is being said that you need, on top of
the hostap_cs driver, a running daemon 'hostapd'. Even though I have
installed and configured that daemon using debian packages, I can't
launch it, even though I have done many trials fiddling with the daemon
config file
#'/usr/sbin/hostapd /etc/hostapd.conf' tells me the following :
ioctl(SIOCGIFINDEX): No such device
hostap driver initialisation failed
rmdir[ctrl_interface]: no such file or directory
My hostapd.conf does not contain much, I left the minimum in it for a start:
interface=wlan0
debug=3
dump file=/tmp/hostapd.dump (nothing in it)
ctrl_interface=/var/run/hostapd
ssid=Livebox46db
.....
if, in the config file, I don't disable 'passive scanning', I get this
reply: "Could not set passive scanning. Unknown error 4294967295"
So, 'hostapd' is not running, which could be a good reason why I can't
connect to my network (DSL box/router). There may also be another reason
: in the doc written by the author of hostap, I have picked this :
"Station firmware version needs to be 1.7.0 or newer to work in WPA mode"
I suppose that the so called 'station firmware', or 'STA firmware', is
the peace of software that is inside the pcmcia card... ? How am I to
know which version it is ? There is nothing written on it for that matter.
Thanks in advance for some more help
Bernard
