Description Bryan Christ 2007-12-04 22:56:49 EST
Description of problem:

WUSB54G USB cannot get IP address with updated kernels.  Only kernel
kernel-2.6.23.1-42.fc8 works correctly.

It also does not matter whether you use the NetworkManager tool or
iwconfig/dhclient manually.

Tested the failure with kernels:
kernel-2.6.23.1-49,fc8
kernel-2.6.23.8-63.fc8

Version-Release number of selected component (if applicable):


How reproducible:

100%

Steps to Reproduce:
1.  Install F8 32-bit 
2.  Plug in Linksys WUSB54G USB adapter
3.  Configure adapter with a with a 40-bit WEP key (open system)
4.  Should work.
5.  Upgrade to newer kernel via yum.
6.  Reboot.
7.  Adapter will no longer fetch an IP address
  
Actual results:


Expected results:


Additional info:

Test system is an HP Compaq dc7100 usdt
Comment 1 Pete Zaitcev 2007-12-05 11:52:05 EST
I have an adapter but not the wireless infrastructure to test.
Please attach the dmesg output from both kernels (do not use the one in
/var/log/dmesg, capture it anew after the adapter fails to work).
The dmesg should also tell if it's p54u or rndis -- same hardware
different versions use different drivers.
Comment 2 Bryan Christ 2007-12-13 11:50:58 EST
Retested with updates from updates-testing:

NetworkManager-0.7.0-0.6.6.svn3138.fc8
NetworkManager-gnome-0.7.0-0.6.6.svn3138.fc8
NetworkManager-glib-0.7.0-0.6.6.svn3138.fc8

kernel-2.6.23.9-85.fc8

Still no change.

Comment 6 Bryan Christ 2007-12-27 14:36:00 EST
Zaitcev,

I thought I would mention that the adapter appears to be using the rt2x00usb
kernel module.
Comment 7 John W. Linville 2008-01-02 14:32:27 EST
The rt2500usb driver version in -42.fc8 is months old -- the jump to -49.fc8 
was too large to easily pinpoint a likely changeset.

I'm copying the main rt2x00 developer to see if he has any insight...
Comment 8 Ivo van Doorn 2008-01-02 17:05:05 EST
Ok, the problem has nothing to do with DHCP. Apparently the device is not 
authenticating and thus isn't even associated to the AP.

(This means this bug is a duplicate of [Bug 9388] Unable to associate rt25xx 
USB key with a WPA AP)

Could you try using wireshark on a different machine to see if the 
authentication requests are leaving the device and if there is a response for 
them from the AP?
Comment 9 John W. Linville 2008-01-03 10:11:51 EST
Bryan, can you provide the information Ivo is requesting?
Comment 10 Bryan Christ 2008-01-04 15:45:29 EST
Unfortunately, this is the only machine I have configured with that adapter and
Fedora 8.  I'd be glad to capture whatever information you need from the one
machine I have, but I'll need some guidance on how to use the tool to collect
the needed info.
Comment 11 John W. Linville 2008-01-04 15:54:09 EST
The machine running wireshark can have any kind of adapter (as long as it 
supports monitoring)...does that change the picture?
Comment 12 Bryan Christ 2008-01-04 16:18:21 EST
Oh, yes indeed.  I have a laptop that participates on the same network. 
Basically, I would just need some instructions on how to capture the information
you need with wireshark.  That is not a tool I am familiar with.
Comment 13 Ivo van Doorn 2008-01-04 17:12:25 EST
Put the interface on your laptop in monitor mode (iwconfig wlan0 mode monitor)
start wireshark (As user with enough privileges)
Select Capture->Interfaces
Press the start button next to your interface.

On your machine with rt2500usb, start the network interface and let it attempt 
a few connections.

If all goes right you will see wireshark reporting a lot of frames, you can 
save those results to a file which you can attach to this bug report.

Wireshark Capture
Comment 15 Bryan Christ 2008-01-04 18:33:48 EST
I tried 3 time with NetworkManager to make a connection while running Wireshark.
 The kernel on the misbehaving system is: 2.6.23.9-85

Comment 16 Ivo van Doorn 2008-01-09 16:40:49 EST
John, please make sure you merge the patch:
rt2x00: Corectly initialize rt2500usb MAC
which I have send to the linuxwireless mailinglist today, that should resolve 
this issue.
Comment 17 Bryan Christ 2008-01-09 16:54:35 EST
I'll be glad to test the patched kernel if someone can provide me with the rpms.

Does this help?
Comment 19 Bryan Christ 2008-01-16 16:15:53 EST
John,

I retested with 2.6.23.13-105 from updates-testing and the problem still persists.
Comment 20 Bryan Christ 2008-02-01 13:01:16 EST
Retested with kernel-2.6.23.14-107 and problem still persists.
Comment 21 Bryan Christ 2008-02-29 18:32:11 EST
John,

Any news on this?
Comment 22 John W. Linville 2008-03-04 14:14:27 EST
No, sorry -- nothing specific.  What is the latest F8 kernel you have tried?
Comment 23 John W. Linville 2008-03-13 11:13:05 EDT
The kernels here contain an update to rt2x00 version 2.1.4:

   http://koji.fedoraproject.org/koji/buildinfo?buildID=42735

Could you give those kernels a try to see if they resolve this issue for you?
Comment 24 Bryan Christ 2008-03-13 11:54:49 EDT
John,

I will try one of these sometime between now and Monday.
Comment 25 Bryan Christ 2008-03-18 13:11:30 EDT
I tried the test kernel you mentioned and it did not resolve the problem.
Comment 26 John W. Linville 2008-03-18 13:16:16 EDT
Please post a new round of dmesg output...thanks!

Comment 28 Bryan Christ 2008-04-24 20:32:16 EDT
Retested with 2.6.24.5-85 from updates-testing and it still does not work.
Comment 29 Bryan Christ 2008-06-05 11:27:56 EDT
I retested with 2.6.25.4-10 from the "updates-testing" repo.  The problem is
still not fixed.

Comment 32 Bryan Christ 2008-08-12 14:30:07 EDT
John,

I haven't forgotten about this bug.  It may be several weeks before I can test this new kernel because that machine is packed in a box until our family is moved.
