Description Roland Wolters 2008-07-12 18:33:18 EDT
Description of problem:
Suddenly I'm not able to login to my WPA-networks anymore. I've tested against 
three different routers. A Windows Vista on the same laptop is able to login 
to these routers, so a hardware failure is unlikely.

Version-Release number of selected component (if applicable):
NetworkManager-0.7.0-0.6.9.svn3675.fc8
wpa_supplicant-0.5.10-5.fc8
0c:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN 
Network Connection (rev 61)
kernel 2.6.25.9-40.fc8

How reproducible:
Try to login to a WPA secured network.
  
Actual results:
It doesn't work. I will attach the /var/log/messages output.

Expected results:
It should've worked. It did so until July 11. At July 10, after the updates, 
it also still worked.

Manual wpa_supplicant attempt.

I tried to login via wpa_supplicant alone - this didn't work either, but there
I cannot guarantee that the wpa_supplicant.conf file was created properly
because I wasn't able to test it.

Using gnome-keyring-manager, I looked at the WPA-PSK password stored in my
keyring and it's a long random string instead of my pre-shared key.  The last
time I did this it showed my pre-shared key.

Never mind, apparently my memory is faulty.  I just downgraded NetworkManager,
wpa_supplicant, and the kernel to:
   NetworkManager-0.7.0-0.6.7.svn3370.fc8.i386
   NetworkManager-0.7.0-0.6.7.svn3370.fc8.x86_64
   NetworkManager-glib-0.7.0-0.6.7.svn3370.fc8.i386
   NetworkManager-glib-0.7.0-0.6.7.svn3370.fc8.x86_64
   NetworkManager-gnome-0.7.0-0.6.7.svn3370.fc8.x86_64
   NetworkManager-openvpn-0.7.0-8.svn3302.fc8.x86_64
   NetworkManager-vpnc-0.7.0-0.6.3.svn3109.fc8.i386
   NetworkManager-vpnc-0.7.0-0.6.3.svn3109.fc8.x86_64
   kernel-2.6.25.4-10.fc8.x86_64
   wpa_supplicant-0.5.10-4.fc8.x86_64

and now I can connect to my WPA network again.  But gnome-keyring-manager still
shows a long string of random characters...

The last downgrade I did was the kernel and that's when it started working, so
I'm going to upgrade NetworkManager* and wpa_supplicant and see if it still works.

This appears to be a kernel bug.  I removed the i386 packages (see bug 455178,
comment #1), then upgraded to the latest NetworkManager* and wpa_supplicant
packages:
   NetworkManager-0.7.0-0.6.9.svn3675.fc8.x86_64
   NetworkManager-glib-0.7.0-0.6.9.svn3675.fc8.x86_64
   NetworkManager-gnome-0.7.0-0.6.9.svn3675.fc8.x86_64
   NetworkManager-openvpn-0.7.0-10.svn3632.fc8.x86_64
   NetworkManager-vpnc-0.7.0-0.7.7.svn3627.fc8.x86_64
   wpa_supplicant-0.5.10-5.fc8.x86_64

Then I tried both the 2.6.25.4-10.fc8 and the 2.6.25.9-40.fc8 kernels and the
WPA network works fine with 2.6.25.4-10.fc8, but it breaks with 2.6.25.9-40.fc8.

Looking at the changelog for kernel-2.6.25.9-40.fc8, there have been a lot of
wireless updates recently.  Apparently one of the changes broke WPA.

Changing component to kernel
Comment 7 Jeff Bastian 2008-07-13 20:20:28 EDT
BTW, I'm on a Lenovo T60 with:

03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network
Connection (rev 02)
