Description Brad Walker 2008-02-21 12:28:32 UTC 
Description of problem: iwl4965 driver doesn't support 4965AGN card.


Version-Release number of selected component (if applicable):
kernel-2.6.25-0.61.rc2.git4.fc9.x86_64


How reproducible: everytime


Steps to Reproduce: Install kernel-2.6.25-0.61.rc2.git4.fc9.x86_64 and boot into it.

  
Actual results:
dmesg excerpt

NetworkManager doesn't show a checkbox for toggling wireless support. Nor do any
scanned netwokrs appear.


Expected results: WLANs visible


Additional info: kernel-2.6.25-0.40.rc1.git2.fc9.x86_64 is the latest kernel my
machine boots and that detects WLANs. I've attached a full dmesg.

Comment 2 John W. Linville 2008-02-21 14:09:12 UTC 
OK, what is happening with the "Failed to initialize wep" thing?  I thought 
that this came down to enabling KMOD, but that is enabled in Fedora kernels.

Any ideas?  Clearly this is an upstream issue as well.
Comment 3 Johannes Berg 2008-02-21 19:27:06 UTC 
No, no idea, but it has been reported upstream as well. If the reporter can
attach the .config file of the failing kernel I can ping Herbert Xu about it
again, he requested that but I couldn't provide it.

Comment 6 Brad Walker 2008-02-21 23:12:26 UTC 
kernel-2.6.25-0.64.rc2.git5.x86_64 seems to have fixed this problem. The device
is enabled and NM shows scanned WLANs. The machine successfully connected to a
WLAN. It's again having problems with the RFKILL switch like bug 432927.
Comment 7 Johannes Berg 2008-02-22 14:00:02 UTC 
So which is the failing and which is the good config?
Comment 8 Brad Walker 2008-02-22 17:34:49 UTC 
Neither of the configs I attached has working wireless. The first one's a
template or something while the second's the actual config of the failing kernel.

The later kernel 2.6.25-0.64 works, but I didn't attach its config. It slightly
differs:

Comment 9 John W. Linville 2008-03-13 15:23:27 UTC 
Does this continue to be a problem with current rawhide kernels?

Comment 10 Brad Walker 2008-03-14 03:21:55 UTC 
John Linville,

All kernels, including kernel-2.6.25-0.113.rc5.git2.fc9.x86_64, since
kernel-2.6.25-0.64.rc2.git5.x86_64 haven't had this WEP problem. However at some
release after kernel-2.6.25-0.64.rc2.git5.x86_64, NetworkManager can no longer
connect the wireless interface to networks, even unencrypted ones. The current
FC8 kernels do the same. I've been running kernel-2.6.23.13-105.fc8.x86_64 for
working iwl4965. I test new kernels whenever they're done building on Koji.

I believe kernel-2.6.25-0.64.rc2.git5.x86_64 solved this particular WEP issue.
Comment 11 Brad Walker 2008-03-14 04:33:46 UTC 
John Linville,

Actually, I can connect to encrypted and unencrypted networks on the 2.4ghz band
w/kernel-2.6.25-0.113.rc5.git2.fc9.x86_64. On the 5ghz band it'll connect to
unencrypted networks but it won't authenticated WPA. Testing on a D-Link
DGL-4500 dual-band router
Comment 12 John W. Linville 2008-03-14 14:08:14 UTC 
It sounds like this issue is resolved.  You may want to open another bug for 
the NetworkManager-related problem you described.
