Re: iwi, hidden SSID and wpa_supplicant problem

2006-10-12 Thread Goran Lowkrantz


Hi,

Reporting back after a few days with the patch. The connect and switching 
between accesspoints work but there are still a few down/up events, about 
once every two hours but that may have somthing to do with the dhcp cleint. 
At the moment, the number of lease renewals match the number of link 
down/up events. I leave this to the clever folks. When running from the em 
interface, I do not see any down/up at all and thet net uses the same DCHP 
server etc.


iwi0: link state changed to DOWN

  You can try using ap_scan=2 or whatever it is in the
  wpa_supplicant.conf file.  This causes wpa_supplicant to use
  directed broadcasts msgs to each ap listed in the file.

 In my case setting ap_scan to 2 doesn't help.

 BTW, I got successfull connection some time ago when I
 start to use /etc/rc.d/netif start iwi0 instead of manual
 running of wpa_supplicant:

 defanbook# ifconfig iwi0
 iwi0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500
 inet 213.189.198.75 netmask 0xfff0 broadcast

 authmode WPA privacy ON deftxkey UNDEF TKIP 2:128-bit TKIP
 3:128-bit txpowmax 100 bmiss 10 protmode CTS roaming MANUAL bintval
 100

 I wrote bssid value to /etc/wpa_supplicant.conf and run
 /etc/rc.d/netif.

 Then I drop connection (netif stop iwi0) and tried to start it again.
 I got associated state in 5-6 minutes.

 In rc.conf I have:

 ifconfig_iwi0=ssid MY-SSID channel 11 WPA

 How can I get -dd output from wpa_supplicant started with netif?
 It could be interesting.

No idea, but a bit more stress testing did reveal a similar problem
here. After I associated with the AP w/ hidden SSID I changed the
channel via webinterface.  The disconnect resulted in the exact problem
you were having.  Only stopping and restarting wpa_supplicant fixed the
issue and I got associated on the new channel.  Not sure what happens
there yet, but something seems to get stuck in an undefined state.


Could you try the attached - untested - patch?  It seems - from looking
at  the linux driver - that we have to remind the firmware of the ESSID
before doing a directed scan.  That explains why it would sometimes work
(whenever we are coming straight from iwi_config) and sometimes not.

Let me know if that improves things for you.  Thanks.

I just tested wireless connection at home with
Linksys WAG54G ADSL WiFi router.

All works fine with your patch.

I plan to repeat test without the patch later.

I attached iwi debug output.

Re: iwi, hidden SSID and wpa_supplicant problem

2006-10-09 Thread Goran Lowkrantz

I have the same problem with an IBM R50 laptop and the iwi driver. From 
dmesg


iwi0: Intel(R) PRO/Wireless 2915ABG mem 0xc0214000-0xc0214fff irq 9 at 
device 2.0 on pci2


I have never been able to connect to a hidden SSID without giving the 
BSSID. If I give the BSSID I can get connection but it takes a long time 
and is not reliable as the driver looses connection and failes to 
re-connect after a while.


When connected to an AP that broadcasts the SSID I still lose connection 
after a couple of hours and have to stop and restart the connection.  Here 
is the sequiece from the console:

Hi.

I have an Asus V6V (V6800) laptop with Intel wireless adapter:
iwi0: Intel(R) PRO/Wireless 2200BG

and FreeBSD installed:

defanbook# uname -v
FreeBSD 6.2-PRERELEASE #3: Mon Oct  9 17:40:59 UTC 2006

I want to connect to access point (cisco 350) with
hidden (not broadcasted) SSID using WPA/TKIP authentication
but still got no success.

Here is my wpa_supplicant.conf:

===

key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP
psk=PASSPHRASE
phase2=auth=MSCHAPV2
}

Here is wpa_supplicant output:

Hi.

[..]
 You can try using ap_scan=2 or whatever it is in the wpa_supplicant.conf
 file.  This causes wpa_supplicant to use directed broadcasts msgs to
 each ap listed in the file.

In my case setting ap_scan to 2 doesn't help.

BTW, I got successfull connection some time ago when I
start to use /etc/rc.d/netif start iwi0 instead of manual
running of wpa_supplicant:

defanbook# ifconfig iwi0
iwi0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500

authmode WPA privacy ON deftxkey UNDEF TKIP 2:128-bit TKIP 3:128-bit
txpowmax 100 bmiss 10 protmode CTS roaming MANUAL bintval 100

I wrote bssid value to /etc/wpa_supplicant.conf and run
/etc/rc.d/netif.

Then I drop connection (netif stop iwi0) and tried to start it again.
I got associated state in 5-6 minutes.

In rc.conf I have:

ifconfig_iwi0=ssid MY-SSID channel 11 WPA

How can I get -dd output from wpa_supplicant started with netif?
It could be interesting.

 Is any of the above the AP you are looking for? (i.e. right bssid).

Yes, 00:07:0e:b8:d8:ee is.

 Strange, why would a broadcast SSID scan turn up less BSSes?  Can you make
 sure you have the dev.iwi.0.antenna sysctl set to 0?

 iwicontrol?  That's no longer useful.  If you really have
 defanbook# uname -v
 FreeBSD 6.2-PRERELEASE #3: Mon Oct  9 17:40:59 UTC 2006
 you should have removed net/iwi-firmware and replaced it with
 net/iwi-firmware-kmod as stated in UPDATING.

Of course, I installed net/iwi-firmware-kmod first.
When I found information about iwicontrol utility and
get it via net/iwi-firmware port. But I did not install
older modules.

So, iwicontrol shows incorrect stat for now? Is there any
other tool to get statistic from iwi device?

 On another FreeBSD box with 6.1-release and same version of
 wpa_supplicant, but with another USB wireless device (ural) all works
 fine.
 I reproduced your setup with a Linksys-54abg and a 2915ABG running a
 recent RELENG_6.  Works like a charm - see attached.

Thanks for feedback, I'll try to play with my home Linksys WAG54G
ADSL WiFi router with the same auth modes.

 Wireless connection in winxp on this laptop works fine too.
 Any ideas?
 If you do have firmware-iwi-kmod and things are still not working properly
 you should try the following:
 1) Disable WPA on AP and see if you can attach w/o wpa_supplicant
 2) See if you can attach w/ wpa_supplicant (key_mgmt=NONE)
 etc. ... to find out which part really is the culprit.  Then you should
 set sysctl debug.iwi=5 and check console output for problems.  Let me
 know how it goes.

OK, I'll do these tests ASAP.

As you can see in my previous reply, I got successfull connection,
but still have strange things while reconnecting, and sometimes
it takes a lot of time. :(

Thanks for your feedback, anyway.

No idea, but a bit more stress testing did reveal a similar problem here.  
After I associated with the AP w/ hidden SSID I changed the channel via 
webinterface.  The disconnect resulted in the exact problem you were 
having.  Only stopping and restarting wpa_supplicant fixed the issue and 
I got associated on the new channel.  Not sure what happens there yet, 
but something seems to get stuck in an undefined state.

Could you try the attached - untested - patch?  It seems - from looking at 
the linux driver - that we have to remind the firmware of the ESSID 
before doing a directed scan.  That explains why it would sometimes work 
(whenever we are coming straight from iwi_config) and sometimes not.

Let me know if that improves things for you.  Thanks.
