Wireless Settings(WLAN) getting lost on Mandrake 9.1(default install)

Hi Folks!

Ok, I am pretty new to Linux. I've been playing around with RH for a while, but still I'd call myself a newbee. :))

Beforehand a bit of information:
Mandrake 9.1

Ok, so far so good. Just to say it in advance. The settings as shown above are all correct (at least as far as I can tell, because NOW everything is working), but my problem is, that linux forgets the wireless settings. After a reboot wlan is not working anymore. The ESSID, AP MACaddr and the Enc key are lost. (maybe othersetting too, but I dont.)

After a reboot I use the "mandrake controlcenter" > "Hardware" > "Harddrake" > then I select the appropiate device - in my case eth0 - and then I use the configuration-tool to re-apply the settings for Enc key and ESSID.

After restarting the network wlan (and internet ;) is working as expected.
My Questions are:
Why doesnt linux store the settings? Do I have to do that manually? If so, where? (Which file?)
Also, if I try to use the command line "iwconfig eth0 key XXXX-XXXX-XX" I'll get an error that the operation is not supported. :( Why is that? I think there should be a working way to re-apply the key without the GUI...I am in linux ....any idea?

I've been looking around in the web and found various information, some helped sorting out different issues (it took me 3days to get the darn thing working ;) but still, I can't sort out this one.

here is additionally the last bit of the /etc/pcmcia/wireless.opts file <Enc key falsified, but IS correct in the original file>
# Generic example (decribe all possible settings)
INFO="Fill with your own settings..."
# ESSID (extended network name) : My Network, any
# NWID/Domain (cell identifier) : 89AB, 100, off
# Operation mode : Ad-Hoc, Managed, Master, Repeater, Secondary, auto
# Frequency or channel : 1, 2, 3 (channel) ; 2.422G, 2.46G (frequency)
# Sensitivity (cell size + roaming speed) : 1, 2, 3 ; -70 (dBm)
# Bit rate : auto, 1M, 11M
# Encryption key : 4567-89AB-CD, s:password
KEY="XXXX-XXXX- restricted"
# RTS threshold : off, 500
# Fragmentation threshold : off, 1000
# Other iwconfig parameters : power off, ap 01:23:45:67:89:AB
# iwspy parameters : + 01:23:45:67:89:AB
# iwpriv parameters : set_port 2, set_histo 50 60

I hope I've delivered enough information and made myself clear... if not, just ask. :))

Any advice or hint is appreciated.

Thanx in advance

...S05harddrake renamed - seems to work now.

apparently it is working now.

since I notice that during bootup harddrake always says saomething like: Card was removed, do you want to configure..."
...well, of course I DONT WANT TO configure it every time I boot up.
So what have I done?


...which is the folder with all the boot-scripts (or rather the links to 'em) for runlevel5 (linux with GUI),

I renamed the script for Harddrake from S05harddrake to BAK.S05harddrake.

I didnt dare to delete, coz wasn't sure on the effect it would have, but apparently it works now.

Maybe someone can explain, I cant. - I just thought some may find this helpful for troubleshooting.

- sometimes Linux is a hassle, but it's.....leaning by doing. -

You can put those values in your ifcfg-ethx script. Here's an archived thread with some detail that may help you.
