Odd, yeah that should work, TL-WN721N is listed as AR9271 and not
AR7010, which ath9k_htc also supports. The AR7010 devices does require
an update usb mode switch [1] but since your device is not AR7010 I do
not think that is the issue here. I take it you are usng
compat-wireless?

CC'ing the Ubuntu kernel team. Hey you guys have any idea on this?

Thanks Luis

Falk, please open a bug against the linux-firmware package for this
issue:

https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+filebug

Unless I've misread something, it sounds like we are just missing the
firmware file. That should be an easy fix.

Thanks,

The original message was clear that the firmware file was available  
and globally readable:

/lib/firmware$ ls -la ar*.fw
-rw-r--r-- 1 root root 51280 2010-07-15 08:51 ar9271.fw

I assume that ath9k_htc comes from linux-backport-modules  
(compat-wireless packaged by Ubuntu).  Then please check that it  
doesn't have a bug fixed by this commit to the compat repository:

     compat: fix uevent_suppress on 2.6.29 or older kernels

     Missing uevent_suppress is causing two uevents instead of one, which is
     confusing udev and sometimes causing firmware load to fail due to race
     condition, so let's add it.

Since it's a race condition, it can explain why the same driver works  
on one system but not on another one.

Please also check commit 8eca4cf0648fad100bd44a0779328f13e6b7d4ca from  
April 28, 2010, also to "compat".  It updates the firmware loading  
code and adds further cleanups.

You can check if dev_set_uevent_suppress() is defined in  
compat-2.6.30.h.  If it's not, you are using an old version of  
compat-wireless for the backport package and it should be updated.

- Ubuntu 10.04 LTS with 2.6.32-21-generic
- compat-wireless from 27.06.2010

Let me clearify, that I am not using the compat ubuntu package but a self
compiled version, so consequently dev_set_uevent_suppress() does not matter.
The network-manager is deinstalled on both laptops. There are two TL-WN721N
cards both work on one laptop but not on the other.

The source of linux-backports-modules-wireless-2.6.32-21-generic is
affected by the race condition!  That's compat-wireless for the original
kernel shipped with Ubuntu 10.04.

It means dev_set_uevent_suppress() is not called for Linux 2.6.30 and 
newer.

2.6.32-22.13 is also affected.  2.6.32-23.16 and 2.6.32-24.17 are not
affected.

It's entirely possible that the Ubuntu linux-backports-modules-wireless
might have priority over compat-wireless.

Also, it's possible that compat-wireless was compiled for a kernel that
you are no longer running.

Please make sure your system is up-to-date.  That should be sufficient.

If you really want to use self compiled compat-wireless, please remove
linux-backports-modules-wireless if it's installed.  In this case, don't
forget to recompile compat-wireless every time you update the kernel.

If you have further questions, please post the output of "modinfo
ath9k_htc" so we know which module you are using.

Actually, I was totally wrong.  The race condition affects kernels
_before_ 2.6.30, so no kernels in Ubuntu 10.10. should be affected.
Sorry for confusion!

That's the Ubuntu package, as expected.

It looks like you have found a different problem with firmware download
that affects the current compat-wireless but not compat-wireless
packaged by Ubuntu.

Actually I thought the Ubuntu linux-backports-modules installs the modules
under /lib/modules/$(uname -r)/cw/ ?

Right, except that you missed "updates" before "cw".  Everything is
installed in one directory with no subdirectories.  Also, the ath9k_htc
driver is not there (I'm using the up-to-date 2.6.32-23 kernel).

So ath9k_htc is from compat-wireless and it didn't work, but installing
linux-backports-modules-wireless made it work somehow.

Ah ok but in this case the user reporting issues would not be using
the Ubuntu package, and instead compiling the modules himself.

I tried Ubuntu 10.10 x86_64 with the current kernel (2.6.32-24-generic)
with compat-wireless-2010-07-23 and without
linux-backports-modules-wireless.  I'm using TL-WN422G.  Everything is
working fine.

By the way, I tried making ar9271.fw an empty file and the resulting
message was "Firmware - ar9271.fw not found".  Perhaps the error
handling would need some improvement.

Hi all,

 

I have problems getting TL-WN721N to work. I have two identical laptops both
with a fresh Ubuntu 10.04 and BIOS Update. On one laptop the wireless usb
device works, on the other one I get the firmware error after one minute
(see below).

 

Do you have any idea, what could go wrong?
