Description

I have just been toying with madwifi-ng for the first time. I have success with it configured as an AP, that is, can get connectivity, ping etc to my madwifi-old clients. but I cannot for the life of me get STA mode working.

With madwifi-old configured as a STA I can see: 

[root@testbench /]# iwlist ath0 scan

ath0      Scan completed :
          Cell 01 - Address: xx:xx:xx:xx:xx:01
                    ESSID:"net_1"
--snip--

          Cell 02 - Address: xx:xx:xx:xx:xx:02
                    ESSID:"net_2"
--snip--

          Cell 03 - Address: xx:xx:xx:xx:xx:03
                    ESSID:"net_3"
--snip--

I can also connect to all 3 networks. But with madwifi-ng all I get is: (with athdebug -i wifi0 0xffffffff & 80211debug -i ath0 0xffffffff)

These continue 2 lines at a time every 5-6 seconds (approx). 

[root@testbench /]# iwlist ath0 scan
ath0: ieee80211_ioctl_siwscan: active scan request
ath0: ieee80211_start_scan: no scanner support for mode 1

ath0      No scan results

[root@testbench /]# wlanconfig ath0 list scan
[root@testbench /]#

strangely enough wlanconfig yields no debug information?

I am running the following:

Notes: This problem was tested by me in r1329 & r1352. It was reported to madwifi-users as thread "Madwifi-ng in STA mode." and has since been reported in madfiwi-users by several other users. As it appears to be not just me, I have now opened a ticket.

Please let me know if there is any more information required, I am happy to run any necessary tests.

Can you please test the patch attached on ticket #238? Just to make sure this isn't another rfkill case.

12/19/05 00:43:39 changed by lists@daniels.id.au

Hi Svens, I tried the rfkill patch from ticket #238, but the result is the same, still no scan or associate.

12/19/05 09:26:11 changed by mrenzmann

Do you have the wlan_scan_sta module loaded?

12/20/05 01:43:48 changed by lists@daniels.id.au

ok, I'm a goose, with module wlan_scan_sta loaded everything is working.

To avoid others having the same problems, I have edited: http://www.madwifi.org/wiki/UserDocs/FirstTimeHowTo

Also I am going to start gathering information on what each module does/is used for, and create a wiki page on that subject.

Thanks, Aaron

  • priority changed from critical to minor.

Thanks Aaron. Out of curiosity: did you enable the kernel feature that automatically loads requested modules? I've seen similar reports lately, which probably also means that support for the mentioned kernel feature could be broken.

  • summary changed from Complete Failure in STA mode (No scan or associate) r1352 to Complete Failure in STA mode (No scan or associate) r1352 (Missing Module).

I dont think the kernel feature is broken (it certianly works on my full linux installs), But it would probably be an issue for users who run systems that do not run modprobe, I have an embedded ARM system.

12/20/05 13:52:23 changed by mrenzmann

I didn't mean that the kernel is broken in this regard, but that MadWifi probably has a bug in one or more places where that feature would be used. modprobe won't deal with this situation anyway, neither with nor without kernel module autoloading support.

12/24/05 02:53:28 changed by miernik@ffii.org

It took me two nights to figure out that I need to "insmod wlan_scan_sta" to be able to scan (I finally got the info from a helpful soul on IRC, thanks kelmo!). I did read madwifi-ng/docs/users-guide.pdf during the first night, and I didn't find the info. I would suggest either better documenting it, or even better making it load by itself when I try to scan.

  • status changed from new to closed.
  • resolution set to fixed.

As of r1408, madwifi-ng prints a message if it couldn't load a scanner module.

01/24/06 07:27:38 changed by mrenzmann

  • status changed from closed to reopened.
  • resolution deleted.

r1408 has been reverted in r1411 - so this issue is back again.

04/23/06 02:06:20 changed by kelmo

  • patch_attached changed.
  • milestone changed from version 0.9.0 - move to new codebase to version 0.9.x - progressive release candidate phase.

This ticket has not been updated in over twelve months and is being marked as "works for me" automatically.

If the ticket is still applies to the head revision of trunk, please re-open the ticket and provide any additional details needed and progress on the problem to date. Thanks.
