Bug 179061 – wpa_supplicant-0.5.7 and ndiswrapper-1.44 does not work well with hidden essid

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Stian Skjelstad 2007-05-18 23:13:19 UTC]

ndiswrapper (upto 1.44 atleast) does not support IW_SCAN_THIS_ESSID (it actually ignores the flag) and wpa_supplicant dislikes that.

You can go around this if you by hand

iwconfig wlan0 essid MYHIDDENESSID

before you run wpa_supplicant, but that is annoying if you have a queue of hidden essid you want it to test

Reproducible: Always

Steps to Reproduce:
1. iwconfig wlan0 essid RANDOMSTRING
2. try to use a hidden essid with wpa_supplicant in mode    ap_scan=1
Actual Results:  
it fails to find the AP when it tries to scan for it specifically

Expected Results:  
To find the AP with the hidden ESSID

Could you post this up to the hostap mailing please please?

Once upstream thinks it's OK then I'll add it to wpa_supplicant.

wpa_supplicant upstream have indicated this is a bad patch as it breaks current association.

Use ap_scan=2 instead.

[Comment 5 Stian Skjelstad 2007-05-19 21:29:32 UTC]

ap_scan=2

does not work. I'll attach the output log (This happens on both my dongles, and same issue with the systems I have access to)

ap_scan=2 output

output from wpa_supplicant with ap_scan=2

[Comment 7 Roy Marples (RETIRED) 2007-05-22 16:47:19 UTC]

Do versions of ndiswrapper later than 1.44 support IW_SCAN_THIS_ESSID?

[Comment 8 Stian Skjelstad 2007-05-23 16:08:28 UTC]

I can't see any relevant in the Changelog for the comming 1.45 release, and I'm not able to login/create an account on their forum either.

[Comment 9 Markus Ullmann (RETIRED) 2007-05-31 11:20:58 UTC]

now that 1.45 is out, does it work for ya?

[Comment 10 Stian Skjelstad 2007-05-31 13:35:50 UTC]

No changes that I could notice.

[Comment 11 Samuli Suominen (RETIRED) 2009-09-27 14:28:16 UTC]

1.55-r1 is current stable as of today. Since last comment is from 2007, closing as TEST-REQUEST. Reopen if it's still a issue.
