(solved) unstable driver with last kernel in kali x86 about 8812au HOT 6 CLOSED

Sorry, my fault. I forgot to kill conflicting apps with:
airmon-ng check kill
Now it works like a charm again.
Could it be possible not to have to kill Network manager?
Thanks for your driver, it is the best for my 8812 device,

from 8812au.

You are welcome.

Answer: Yes, I have been working on a new guide. It seems to work well here. Can I get you to test it and advise?

Test Monitor Mode

Setup:

Install the aircrack-ng package

$ sudo apt install aircrack-ng

Ensure Network Manager doesn't cause problems

$ sudo nano /etc/NetworkManager/NetworkManager.conf

add

[keyfile]
unmanaged-devices=interface-name:mon0;interface-name:mon1

Note: The above tells Network Manager to disregard two interfaces.
I usually just use mon0 for monitor mode. I have two usb adapters
on my main box and doing it this way allows me to continue in
managed mode with internet access while I use the other adapter
for monitor mode.

Enable monitor mode using iw and ip:

$ sudo iw dev

phy#0
	Interface wlan0
		ifindex 3
		wdev 0x1
		addr 00:c0:ca:ad:4b:cc
		type managed
		txpower 12.00 dBm

$ sudo ip link set wlan0 down
$ sudo iw phy phy0 interface add mon0 type monitor
$ sudo ip link set mon0 down
$ sudo iw mon0 set monitor control
$ sudo ip link set mon0 up
$ sudo iw dev mon0 set channel 36 (or whatever channel you want)

Test injection

$ sudo aireplay-ng --test mon0

Test deauth

$ sudo airodump-ng mon0 --band ag

$ sudo airodump-ng mon0 --bssid <MAC address of router> --channel <channel of router>

$ sudo aireplay-ng --deauth 0 -c <deviceMAC> -a <routerMAC> mon0 -D

Please let me know how it goes and what changes I need to make. I realize this needs to be better documented so maybe you can help me with that.

Hello, it seems that it does not work.

Using "airodump-ng mon0 --band ag" it does not find any ap in any channel (a or g band).
After I executed "airmon-ng check kill" and aireplay-ng anf airodump-ng work again.
One more thing is that even when I kill NetworkManager and it works in dmesg there are two warnings. I attached the file with them.

How did wlan0 get to be type monitor? It should not be monitor.

Before executing the steps I posted, you really need a clean fresh boot and don't run airmon-ng.

Hello, fresh boot. It seems that when executing "iw phy phy0 interface add mon0 type monitor" already puts mon0 in monitor mode. "iw mon0 set monitor control" also puts wlan0 in monitor mode.

Okay, I was testing with an adapter that has a mt7612u chipset on a Linux Mint box. Let me see about setting up an adapter with a rtl8812au chipset on a Kali box to see what the difference is with the Realtek driver.

Yes, I am aware that some of the lines are not needed in some situations. I try to avoid using "airmon-ng check kill" myself. The setup with mon0 works well here with my main box but let me check it in your setup. Will report back.
