           Summary: Random No ProbeResp - assume out of range
           Product: Networking
           Version: 2.5
     KernelVersion: 2.6.29-rc3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Wireless
        AssignedTo: networking_wireless at kernel-bugs.osdl.org
        ReportedBy: mordae at anilinux.org


Latest working kernel version: 2.6.26
Earliest failing kernel version: 2.6.28
Distribution: Debian Sid
Hardware Environment: iwl3945 (Thinkpad R61)
Software Environment: wpa_supplicant 0.6.4-3, wireless-tools 29-1.1
Problem Description:

After some time (totally random, ranges from several minutes to several hours)
following kernel message appears and I am disconnected from the AP:

[31719.537037] wlan0: No ProbeResp from current AP 00:1b:fc:57:a9:90 - assume
out of range

After that, I can no longer connect and have to remove whole mac80211 stack
from the kernel with:

ifdown --force wlan0
rmmod iwl3945 mac80211 lib80211 cfg80211

Then put modules back and reconnect.

I am using following wpa_supplicant options:

  key_mgmt=WPA-PSK
  proto=RSN
  pairwise=CCMP
  group=CCMP

Googling suggests that I am not alone in this and several other users are
experiencing this with 2.6.27, but I can not confirm that. Some suggests
increasing IEEE80211_MONITORING_INTERVAL in net/mac80211/mlme.c to more than
2HZ, which I am going to try right after this report.


Steps to reproduce:

Connect to an AP with wpa_supplicant configuration above and wait. I am not
able to test with an open wifi in a near future.
