USB Alfa AWUS036NHA adaptor connection loss dmesg, ifconfig, iwconfig output added.

[Hesus]

Hi there,

I am having trouble keeping my Alfa AWUS036NHA wireless adapter stable, every time i put it in monitor mode it gets unstable and loses connection with the network.

1. Kali version (kali Rolling 2016.2

Linux kali 4.6.0-kali1-amd64 #1 SMP Debian 4.6.4-1kali1 (2016-07-21) x86_64 GNU/Linux

2. Kali installation : kali has been installed on a separate SSD to dual boot with windows 10 which is installed on a second HDD.

3. Basic output of commands

airmon-ng start wlan0 (when i do this the wifi connection gets lost same goes for doing the airmon-ng check kill command) :

airmon-ng start wlan0

Found 3 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to run 'airmon-ng check kill'

		(mac80211 monitor mode vif enabled for [phy4]wlan0 on [phy4]wlan0mon)
		(mac80211 station mode vif disabled for [phy4]wlan0)

When is stop monitor mode i need to use the command ifconfig wlan0 up to get it up again.

iwconfig :

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm

          Encryption key:off
          Power Management:off
          
eth0      no wireless extensions.

After this i need to reboot to get the adapter to work again.


I have tried to update the driver software, when i do this it tells me that the drivers are up to date, i updated the firmware as well.

I am kinda new to all of this so if you need some extra information please let me know so that i can provide it for you.

Thanks in advance.
