Lately I install ipw2200 on Debain Sarge 3.1 r0a. The hardware is HP NC6230 (laptop).
However, after software installed, seemly the networking still don't work at all.
So I check the syslog (/var/log/syslog), as follow:
ep 17 16:43:17 kernel: [4295850.485000] Kill switch must be turned off for wireless networking to work.
This is probably the source of the problem. According to this thread you aren't alone. If I'm reading the thread correctly you either need to mess with the card settings in BIOS or you need to install the rfswitch software.

thanks your reply.
yet after trying several strategies, i still failed to get it (ipw2200) worked.
for it still issues message in /var/log/syslog with
Code:
ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.
i have rfswitch installed already.
Code:
pbe5: Radio turned ON
fsam7400: SW RF kill switch for Fujitsu Siemens Amilo M 7400, v0.4.0
fsam7400: Copyright(c) 2004 zwobbl ;)
fsam7400: physical memory f0000-100000 mapped to virtual address c00f0000
fsam7400: no supported wireless hardware found
the message appears just right after the ipw2200.
and i enter to the bios setup mode to test few possibilities.
however, it looks like useless.
the hardware i use is HP NC 6230.
Would anyone can tell me what else i can do in order to get ipw2200 worked? or where there's resource (related to hardware/ bios are welcome 2) [the manual shipped with the product doesn't talk too much about this]?
Well.. I have that problem too.. what I do to resolve it is to go to /etc/discover.conf and remove de boot all line.. So only hotplug daemon will load de modules.. and then voila.. it works..
If you want to test if it works only do this..
modprobe -r ipw2200
modprobe ipw2200
after the system reload the module this line "ipw2200: Radio Frequency Kill Switch is On:" will desapear and then you can use wireless.. however I have a problem to connecting to WEP APs and I dont know how to resolve.. it..

I hope it helps you..
And sorry for my bad english..
After reading your post, I tried to remove the line
Code:
boot all
in the /etc/discover.conf. but it seemly did't work.
I was still able to see the line
[code]
ipw2200: Radio Frequency Kill Switch is On
[code]
in the /var/log/syslog, even though I removed the syslog and rebooted it again.
Nevertheless, I appreciate your reply, sincerely; )
Ok. I stumbled upon this thread after getting the same "ipw2200: Radio Frequency Kill Switch Is On:" message.
After wrecking my brain thinking about what could be causing this and trying different things and none of them working, I decided to think about what I had done recently that might've involved changing networking settings.
I have a dual boot system and I wanted to move things from my linux partition to my NTFS partition. I do this by moving the files to a samba share on my desktop machine, and then booting to Windows and moving them from the samba share to the NTFS partition. Since it was a pretty big load, I wanted to do it through the ethernet interface 'cause it would take hours through wireless. So I remembered I had deactivated the wireless card under Windows to activate the ethernet card. I booted back to Windows, activated the wireless card, and booted back to Linux.
Problem solved.
It seems that the card stays deactivated regardless of the operating system, once you've turned it off under Windows. Apparently it's a hardware setting, and not an OS setting. So, as simple as it is, this was the reason for my problem, and that was the simple solution.
Maybe more people have been in the same situation.
I hope this helps.

Maybe I should ask this question on the hardware forum.
Thanks your reaply.
I appreciate it.; )

Like, the light for the wireless in the lower left is lit up?
If not, there is something like function+F2 (or similar) that turns wireless on/off
Yes, I did see that the light is on after operating system successfully starting up. However, if I push that button (button to activate and disactivate the centrino) to turn the light off. Then, I cannot turn it on again. (the light is always off)

Does it mater? What should I do?
I appreciate your reply.
By the way, I try to use command '/etc/init.d/networking restart' to test weather I am able to get the IP address when the wireless light is on. It, then, appears the following message.
Code:
Setting up IP spoofing protection: rp_filter.

exiting.
Failed to bring up wlan0.
and my interfaces seeting for wireless is
Code:
auto wlan0
iface wlan0 inet dhcp
wireless_mode Managed
wireless_essid Wireless
wireless_channel Auto
Because the action I did to obtain the IP was when the light was on, does it mean that it's only the problem of the wireless setting in interfaces file?
