    Unhappy How to install the Adapter Wi-Fi TP-LINK TL-WN721N (AR9271 0cf3 9271)


    Hi everyone!

    Just bought a Wi-Fi Adapter TP-LINK TL-WN721N and am having trouble installing it on Ubuntu.


    1) My sistem:

    $ uname -a
    Code:
    Linux wfs 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012 i686 athlon i686 GNU/Linux
    $ cat /etc/lsb-release
    Code:
    DISTRIB_ID=Ubuntu
    DISTRIB_RELEASE=12.10
    DISTRIB_CODENAME=quantal
    DISTRIB_DESCRIPTION="Ubuntu 12.10"
    2) The hardware is recognized for the system:

    $ lsusb
    Code:
    Code:
    Bus 001 Device 004: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

    3) I tryed install with the procedure bellow:

    $
    Code:
    Code:
     sudo apt-get -y install build-essential linux-headers-generic linux-headers-`uname -r`
    
    $ mkdir htc_9271
    $ cd htc_9271
    
    $ wget wireless.kernel.org/download/compat-wireless-2.6/compat-wireless.tar.bz2
    $ tar -xvf compat-wireless.tar.bz2
    
    $ cd compat*
    $ sudo make
    $ sudo make install
    $ cd ..
    
    $ wget wireless.kernel.org/download/htc_fw/1.3/htc_9271.fw
    $ sudo cp htc_9271.fw /lib/firmware
    
    $ sudo modprobe ath9k_htc
    4)the module was installed:

    $ modinfo ath9k_htc
    Code:
    filename:       /lib/modules/3.5.0-17-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_htc.ko

    Are you sure you needed that driver? Where did you get it?
    Do you also have the dependency modules loaded?

    Code:
    depends:        ath9k_hw, ath9k_common, mac80211, ath, cfg80211
