Raspberry Pi 3 problem with TL-WN722n WiFi Adapter (Atheros AR9271)

[kachevan.op]

Hello

I'm trying to use my wifi adapter with TP Link TL-WN722n (Atheros AR9271) with freshly installed Kali (kali-2.1.2-rpi) on Rpi 3.
What I did :

apt-get update
apt-get upgrade
apt-get install firmware-atheros

checked ifconfig & iwconfig, shows no wireless :

root@kali:~# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

lsusb shows adapter :

root@kali:~# lsusb

tried doing modprobe

root@kali:/lib/modules# modprobe ath9k_htc
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.1.19-v7+/modules.dep.bin'
modprobe: FATAL: Module ath9k_htc not found in directory /lib/modules/4.1.19-v7+

/lib/modules/ only contains 4.1.19 directory

root@kali:/# ls -ls /lib/modules/
total 4
4 drwxr-xr-x 3 root root 4096 Dec  3 17:17 4.1.19

OS (via uname) :
Linux kali 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l GNU/Linux

Any advice or help would be highly appreciated !
