issues while attempting ath9k_htc to work with ubuntu 10.04, device TL-WN721N

[Yatharth]

I am trying to install driver for the TP-LINK : TL-WN721N (Wi-Fi USB
Device). If this is not the sort of issues this mailing list is for,
please let me know.

This device should use the ath9k_htc driver

./lsusb
Bus 001 Device 003: ID 0cf3:9271 Atheros Communications, Inc.

I have followed the instruction from 
http://linuxwireless.org/en/users/Download 
<http://linuxwireless.org/en/users/Download> But they do not seem to 
work for me

When I modprobe ath9k_htc

Ubu-VM:/lib/modules/2.6.32-22-generic/build$ sudo modprobe ath9k_htc

FATAL: Error inserting ath9k_htc

You haven't unloaded the existing ath9k_hw module.

Do a 'sudo make install' in your compat directory, and
then 'sudo make unload'.

Check 'lsmod | grep ath'. If anything is still present, unload all of them,
along with mac80211, cfg80211. Then modprobe ath9k_htc.

Of course, you can just reboot after 'sudo make install' and things should work.

I had checked earlier to ensure that everything was unloaded.

But I've done it again to make sure.
Step 1 :  'sudo make unload'
Step 2 : 'lsmod | grep ath'  [Returns Nothing, thus indicating none of 
these modules are loaded]

If I do 'modprobe ath9k_htc' after this, I still get the same error

What does 'modinfo ath9k_hw' show ?

What is the 'cw' directory ?

On my machine, modinfo -n ath9k_hw shows:
/lib/modules/2.6.32-22-generic/updates/drivers/net/wireless/ath/ath9k/ath9k_hw.ko

You have some stray modules in your system, clean them up
and reload the driver.

Its ubuntu's compat-wireless package, linux-backport-modules. Try to
uninstall that or rm -rf it.

Thanks Sujith & Luis that fixed it. I can now see the device and use it 
correctly.

I remove the 'cw' directory and then

'sudo make install'
'sudo make unload'
'sudo modprobe ath9k_htc'

I did install the compat-wireless package, I believe I did it while 
self-debugging the issue without knowing the implications.
