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

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

tried doing modprobe

root@kali:/# ls -ls /lib/modules/

OS (via uname) :

Any advice or help would be highly appreciated !

Hi kachevan.op,

The TP Link TL-WN722n should work out of the box, no need to install additional firmware.
I just did a fresh install and plugged it in. It got picked up straight away and I could connect to my local WiFi.
Why don't you try again without installing the firmware package?

Hope hat helps,

Thanks for the reply !
Just tried, this is from newly installed image (no updates, nothing):

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

eth0      no wireless extensions.

root@kali:~# uname -r

Can this be a problem with the image ?
I've noticed on your website that you use kali-2.0.1-rpi2.img I use kali-2.1.2-rpi.img

Also could you kindly say what is your linux version, does it have -v7+ ?

So embarrassing :

I've just realised I've being using wrong image all the time !
Used kali-2.1.2-rpi instead of kali-2.1.2-rpi2...

I will have to try the correct image.

With the correct image everything is working just fine.

Dear mods can you please delete this thread ?

Even I am using Kali 2.1.2 rpi2 on raspberry pi 3 but the adapter is not working.

I'd update to Kali 2017.2 before going any further.
Do you know which HW version of TL-WN722n you are using? The above threat was dealing with version 1 (Atheros) but you might have the other one using a Realtek chipset. That one's known to cause a little grief.
These links might help to identify the version:

Hi mickeyi,

apt install firmware-atheros

should fix your problem.
