AWUS036ACH and driver issues

[misha01]

Hello.

I've been searching all over the place and haven't found anything that has helped me. There isn't a lot of information on the AWUS036ACH, and it uses a different chipset than most of the other adapters.

This wireless network adapter is using the Realtek RTL8812AU chipset. The driver's for this are not in Kali, so they need to be installed. I tried to install the driver's from the CD, however this seems to mess up the entire installation and required me to reinstall. I don't recommend it. Realtek has no mention of this adapter on their website, so you won't find much on there. On the Alfa Network website, I was able to download some drivers dated 2015/05/07. I installed these drivers and Kali is recognizing the device. However, it's not quite functioning normally.

root@kali: ~# iwconfig
eth0 no wireless extensions.

wlan0 IEEE 802.11abgn ESSID: off/any
Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm
Retry short limit:7 RTS thr: off Fragment thr: off
Encryption key: off
Power Management: off

lo no wireless extensions.

wlan1 unassociated Nickname: "<WIFI@REALTEK>"
Mode:Managed Frequency=2.412 GHz Access Point: Not-Associated
Sensitivity: 0/0
Retry: off RTS thr: off Fragment thr: off
Encryption key: off
Power Management: off
Link Quality: 0 Signal level: 0 Noise level: 0
Rx invalid nwid: 0 Rx invalid crypt: 0 Rx invalid frag: 0
Tx excessive retries: 0 Invalid misc: 0 Missed beacon: 0

The device has been assigned to wlan1. However, when I run airmon-ng:

root@kali:~# airmon-ng


Interface Chipset Driver

wlan0 Intel 6300 iwlwifi - [phy0]

It's not recognizing wlan1.

Can anyone give me some suggestions or advice on how to get this network adapter to work properly?

Update:

I found some driver's at this location
https://github.com/abperiasamy/rtl8812AU_8821AU_linux

I installed them using the instructions in the README with dkms. Then I plugged in my adapter and it worked. I can use the network. Airmon-ng saw the adapter and was able to start a monitor (mon0). I started up another monitor on wlan0 and tried a test.

root@kali: ~# aireplay-ng -9 -i mon1 mon0

As you can see, injection is not working. I do not recommend this adapter. If someone knows a good dual band adapter that works with injection, please let me know.
