You need to edit your /etc/wpa_supplicant.conf and add ap_scan=2 this allow you to search for hidden ap's. Before I made this change I was not able to locate my ap.

ap_scan=2
network={
ssid="APNAME"
proto=WPA
scan_ssid=1
key_mgmt=WPA-PSK
psk="Secret Key"
group=TKIP
pairwise=TKIP
}

I also had to change the networking start script to S41networking.

sudo rm /etc/rcS.d/S40networking

sudo ln -s /etc/init.d/networking /etc/rcS.d/S41networking

I added wpasupplicant to the /etc/rcS.d/ directory to start at S40wpa_supplicant.

sudo ln -s /etc/init.d/wpasupplicant /etc/rcS.d/S40wpa_supplicant

The start script order change was because I noticed wpasupplicant was sTarting after networking.

I am also using the default start script for wpasupplicant.

I hope this helps some people get connect thise who can't get IP's this will help.

Luca great job on the how to you might want to add some of this to it.

Thanks for the suggesting, I'll add it to my HowTo.
Anyway, as said in the wpa_supplicant documentation, "scan_ssid=1" allows the scanning with SSID-specific Probe Request frames (this can be used to find APs that do not accept broadcast SSID or use multiple SSIDs; this will add latency to scanning, so enable this only when needed).
While "ap_scan=2" let wpa_supplicant performing the scan instead of the driver.
So, I think there may be a bug in ipw2200 on some system configurations and only add the "ap_scan=2" option if you get troubles finding your AP.

Re: HOWTO: ipw2200 + wpa

First of all, thanks Luca for this excellent HowTo it is very nice for a Newbee like me to have a detailed step by step HowTo like this.

I have the exact same problem as MadJeff (post #198 ) and I am sure that I have run the "sudo sh remove-old" command in the ieee80211-1.0.3 directory.

I have an IBM T42 if that is for any help.

Thanks

Re: HOWTO: ipw2200 + wpa

What's the output of "sudo sh remove-old" command?

Re: HOWTO: ipw2200 + wpa

This is the output from the "sudo sh remove-old" command:

Code:

Checking in /lib/modules/2.6.10-5-686/ for ieee80211 components... /lib/modules/2.6.10-5-686/kernel/drivers/net/wireless/ieee80211 Above files found. Remove? [y],n y

But then when I run the "make" command I get this:

Code:

Checking in /lib/modules/2.6.10-5-686/build/ for ieee80211 components... /lib/modules/2.6.10-5-686/build/include/config/ieee80211 Above files found. Remove? [y],n y Old ieee80211 references found. In order to build the ieee80211 subsystem, prior versions must first be removed. You can perform this task by running this makefile as root via: % sudo make check_old and answering Y to remove the file references. Aborting make. make: *** [check_old] Fejl 1

Then when I run the "sudo make check_old" command I get the same error as above.

Have you press the "y" key and then Enter after "sudo sh remove-old", haven't you?

Re: HOWTO: ipw2200 + wpa

Yes.

But I've forgot that the first time I ran the command I got this error, but I took a screenshot. Sorry if I should have brought this up before. Here it is:

http://users.cybercity.dk/~dsl195400/screen_error.png

The text at the end of the two last lines says: No such file or directory.

But I don't know if that have something to do with the problem.

Here's a complete run of the procedure up to the point where it fails:

As I stated before, I wiped and reinstalled just in case I had some extra bits floating around, so this is on a clean install, but I'm still getting the same issue.

Luca you are correct about a bug in ipw2200. I tried it again without ap_scan=2 and could not find my ap. scan-ssid=1 does not correctly configure somthing. So I just commented it out and using the ap_scan. Working great I appreciate you not flaming me. It says I am a newbie but I have played with alot of distro's and I am a Linux SA for Sprint.
