Package: wpasupplicant
Version: 1.1-1
Severity: grave
Justification: renders package unusable
After an updare in the last days my wifi interface cannot associate to my
access point any longer. I have tried to use wpa_cli and I've got the
following
result:
The wpasupplicant package was last updated on february 21st, so unless
you haven't upgraded your system for one and a half month [1], it's
certainly not the wpasupplicant package which broke your ability to
connect to your wireless network. Besides that, grave is a heavily
inflated severity for this problem, unless you have a strong reason to
believe that wpasupplicant is indeed broken for everyone and any
imaginable purpose, not 'just' your own system (I realise that your
problem can be annoying enough, but it's far from grave). As a matter
of fact, wpasupplicant 1.1-1 is working fine on 33, mostly
different[2], wlan cards on up to date unstable systems for me.

This looks like a kernel issue, probably specific to the iwlegacy
driver for iwl3945. But the information you've presented so far isn't
comprehensive enough to make and educated guess.
3Associated with 00:0c:f6:a1:ba:98
3WPA: Key negotiation completed with 00:0c:f6:a1:ba:98 [PTK=CCMP GTK=CCMP]

...and at this point it looks as if it had associated correctly, but
you're omitting eventual dmesg messages and the output of
wpa_cli status here, so we don't know where it fails, at assoc, auth
or further up the stack when requesting an IP address.
my lsmod returns:
iwl394558397 0
iwlegacy 55017 1 iwl3945
mac80211 450945 2 iwl3945,iwlegacy
cfg80211 394809 3 iwl3945,iwlegacy,mac80211
the wifi and firmware installed packages are:
ii firmware-iwlwifi 0.41 all
The firmware is up to date (although there haven't been any updates
for iwl3945 in years), so this is a good sign.
[...]
Kernel: Linux 3.13-1-amd64 (SMP w/2 CPU cores)
[...]
So kernel 3.13, I'm not aware of any known issues here either.
My gut feeling suggests that this is more likely a problem with your
kernel (although iwlegacy is in deep maintenance mode, so there haven't
been many changes to its code recently) or a problem with your local
infrastructure (access point or wireless interference), but I have way
too little information to venture into reassigning to src:linux for
now.
Please provide further information about your wlan configuration (you
should use nl80211, not wext as driver type for wpa_supplicant; your
report doesn't suggest your setting), the required encryption type
(unencrypted, the various WEP or WPA flavours), your complete dmesg
(at least the debugging information for your wlan card and its
regulatory domain settings) and the output of wpa_cli status and
what debugging information appears when you let wpa_cli running in
interactive mode for a few minutes (e.g. if it goes into an auth/
deauth loop). It would also be tremenduously helpful if you could try
to find out what might have broken your previously working setup, by
checking which packages were installed/ upgraded in comparison to your
last known-working state (/var/log/{apt/,dpkg.log} should help here).
For testing, it probably won't hurt to restart your access point as
well, as these can also freeze or hang.
