Alfa Awus036H, strange behaviour and dropped connection

Hello everyone,

I have ordered Alfa Awus036H (RTL8187 chipset) about 1 week ago and still trying to make it working with Kali.
Let me explain the whole issue:

I have running Kali in my both desktop & laptop.
Kali is working under VMware environment.

However, my connection (not monX interface, just wlan0) is dropping every 1-2 minutes.
Actually connection drops on some actions like:
- Running ettercap
- Any ARP command
- Port scanning

It looks like device is not responding at all, i have to re-plug it to USB.
And also, i have tested it on Windows, connection is really slow.


I have changed the USB cable with USB Y-cable, not changing anything.
I made further tests and plugged my TP-Link adapter (Atheros chipset) and everything seems fine.

There are mixed responses and solutions for my situtation, i have tried all. (Disabling network-manager, setting TX power, trying to install drivers which is unnecessary on Kali)
I am willing to order a new adapter if Alfa is really buggy on Kali (or any OS)

However, i would like to find a solution and the root of issue.
Any ideas on my situtation?
I can send detailed logs, even enable remote vnc or anything to resolve this.

Thank you all.

This happen to me as well. any solutions?

Returning device to seller, no solutions for me.

Happen to me as well, with both of my ALFA cards. the Alfa AWUS036H , Alfa AWUS036NHA
Unsure how to troubleshoot the problem either. sometimes it will just quit working and the terminal will freeze.

I have the same problem as well. I'm surprised there's no solid solution for this. It's a known issue with the RTL8187 driver from what I'm reading.

Supposedly rmmod rtl8187 && rfkill block all && rfkill unblock all && modprobe rtl8187 && rfkill unblock all && ifconfig wlan0 up should fix it. Though when I did this, I still had problems.

I have same problem, I just unplug it and plug it back in, some applications it happens all the time, others its rare. It happens a lot in a few of the applications where monitor mode is necessary. Not a big deal to me as I just unplug and restart monitor mode, other than that the devices are great. I am thinking of testing with a new device, maybe tplink next.

Same exact problem. Maybe we need to submit a bug report.
My terminal will freeze as well.
