More information about the wireless card is needed, before we can offer much help. Please read through the link below, and post the info that it telsl you how to find.

hi.This file consist of running iwconfig,lsmod and /sbin/lspci -nn .
thank u for help.

Thank you for the information.

This is the wireless card:

Code:

06:05.0 Network controller [0280]: Intel Corporation PRO/Wireless 2200BG Network Connection [8086:4220] (rev 05)

And this is the driver that is loading for it:

Code:

Module                  Size  Used by 
ipw2200               134665  0

According to the web site for the driver, you need firmware for this to work:

Intel® PRO/Wireless 2200BG Driver for Linux

Post the output of this command:

Code:

dmesg | grep firmware

Hi.this file contain output of "dmesg" command.
thank you Paul very much .

**waterhead** · 02-19-2009

Although it was missing the firmware messages, I did find this:

Code:

ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection 
ipw2200: Radio Frequency Kill Switch is On: 
Kill switch must be turned off for wireless networking to work.

There must be a way to turn the wireless off/on using either a dedicated switch, maybe on the side of the laptop, or using shortcut keys on the keyboard. There is a way to do this with commands, but it is a bit complicated. Try using the "switch" first.

Also, I need to know if it is loading the correct firmware. Try this command:

Code:

dmesg | grep ipw2200

The latest kernel makes it easier to deal with the rfkill switch. since Fedora 8 is getting rather old, if you can install Fedora 10 it may help to get this working.

the shortcut to switch the wireless card "on" is Fn+F10.but it cant turn it on.
I agree on you to change my fedora version,to 10.
output command of demesg | grep ipw2200 is :

Again, thank you for the info.

We can try to activate it on Fedora 8, it just will take some doing. You need to find the place where it registers the state of the wireless. Depending on the driver, it will be in a different folder. In more recent kernels, this has been standardized and easier to locate.

The file that I am looking for is rfkill, or it could be a folder/file named /rfkill/state. I don't have any info on your specific driver, but I found some for the iwl3945. To see the state of that wireless, on that system, this command would be used.

Code:

cat /sys/bus/pci/drivers/iwl3945/module/drivers/pci\:iwl3945/0000\:10\:00.0/rf_kill

The backslashes are added before the semicolons, and aren't actually in the path name. You need to locate the similar path for your wireless. It would obviously be in a folder named ipw2200. It would be in the /sys/bus folder, that is all I can tell you. A better path to look for it may be this:

/sys/bus/drivers/(ipw2200?)

Once you locate it, post back with the full path to it. You could try to poll it, (with the cat command) to see the state.
0 = disabled
1 = enabled

Let me know what you find, and how you do. I told you that it was complicated.

hi.I found it (rf_kill) on this path :/sys/bus/pci/drivers/ipw2200//module/drivers/pci:ipw2200/0000:06:05.0/rf_kill.
and eventually could changed its content (change to 1 for enabling it).but nothing happened.it means that wireless nic still off.the value of this file in my laptop is
"0" or "2". "0" means that radio frequency is off and "2" means radio frequency is unassociated.when i could manually changed its content (to 1),the radio frequency didnt change and ,again was off.(to changed the content of rf_kill, created another file with the content of "1" and copy this content to the rf_kill with the "cp -P command")

**waterhead** · 02-20-2009

Don't get too far ahead on this. I don't recall the exact command to change it, and my notes are at home. I'm at work, and it's lunch time. Yum Yum!

When you manually change the state, you have to cycle the wireless on/off with the ifdown and ifup commamds.

I'll post back with more details later, when I get home.
