Firmware - htc_9271.fw download failed - USB Wireless Adapter Problems

[golfsoccer9]

Hello, I recently purchased a TP Link TL-Wn722n USB Wireless Adapter for some penetration testing. I thought that the setup and everything would be simple, but I don't know what is going wrong? I've setup my network settings for bridged adapter and everything, and then I connect the USB Adapter to the VM. Upon doing this though, the green blinking light on the adapter stops blinking (possible problem?). Anyways, I run ifconfig and it doesn't show any wlan0 interface. In addition, iwconfig shows no wireless extensions.

The LSUSB command shows:

 LSUSB:  
device 002: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n

When I run #dmesg | tail it says:

dmesg | tail:
ath9k_htc: Firmware htc_9271.fw requested
registered new interface driver ath9k_htc
ath9k_htc: Firmware - htc_9271.fw download failed
ath9k_hts: USB layer deinitialized

I've checked in my /lib/firmware file for both the ar9721.fw and the htc_9271.fw files, and they're both there.

Not sure if this is relevant, but my kernel version as displayed through the command uname -v is:

#1 SMP Debian 3.\.2-0+kali8

uname -a

Linux Kali-VM 3.7-trunk-amd64 #1 SMP Debian 3.7.2-0+kali8 x86_64 GNU/Linux

I'm running Kali Linux as a Virtual Machine in VirtualBox. Any helps, tips, or suggestions will be greatly appreciated! Thanks in Advance!!

How did you installed the firmware?..Did you installed from repos, from github or from other link?

When installing from repos: aptitude install firmware-atheros....

But if you installed in different way, you need to compile and copy it not in /lib/firmware, in debian iit uses: /usr/local/lib/firmware/

So please, be more specific as to How you installed it.

I can confirm

aptitude install firmware-atheros

Worked for me in this situation

Thanks
