Red Hat Bugzilla – Bug 455150
Not able to login to WPA networks anymore
Last modified: 2008-07-14 09:26:21 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):
0c:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN
Network Connection (rev 61)
Try to login to a WPA secured network.
It doesn't work. I will attach the /var/log/messages output.
It should've worked. It did so until July 11. At July 10, after the updates,
it also still worked.

Output of /var/log/messages during a failed login attempt.

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:
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
Then I tried both the 126.96.36.199-10.fc8 and the 188.8.131.52-40.fc8 kernels and the
WPA network works fine with 184.108.40.206-10.fc8, but it breaks with 220.127.116.11-40.fc8.
Looking at the changelog for kernel-18.104.22.168-40.fc8, there have been a lot of
wireless updates recently. Apparently one of the changes broke WPA.
Changing component to kernel
BTW, I'm on a Lenovo T60 with:
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network
Connection (rev 02)
