How to find rtl8821au drivers for Kali

[klaus10000]

I was wondering how to find the driver for the Meross AC600, that require the Realtek rtl8821au driver.
The included drivers do not compile.
Any other git hub repository for the rtl8821au do not compile.
Any help?
regards

I thiink this github respo may work :

https://github.com/aircrack-ng/rtl8812au

May be Kali's respo also work as it uses the captioned respo as main stream :

apt install realtek-rtl88xxau-dkms

If it does not work, please run the following command :

lsusb

to get the hardware id and add below the line 199 of https://github.com/aircrack-ng/rtl88...nux/usb_intf.c and then recompile it.

Good luck!

The Kali respo, realtek-rtl88xxau-dkms, covers the rtl8812-rtl8814 drivers, not the rtl8821. And this is confirmed by the fact that the usb wireless is not recognized.
The github.com/aircrack-ng/rtl8812au is the 12, and not the 21, and not compile (or I'm not able to make it compile, I can show the errors).

Update 1:
So, with the commnd lsusb I've spotted the usb device
Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:8008 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 0781:5583 SanDisk Corp.
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 005: ID 04f2:b3ed Chicony Electronics Co., Ltd
Bus 003 Device 004: ID 138a:003f Validity Sensors, Inc. VFS495 Fingerprint Reader
Bus 003 Device 008: ID 0bda:a811 Realtek Semiconductor Corp.
Bus 003 Device 007: ID 8087:07dc Intel Corp.
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It should be the Realtek one line.
I've modified the usb_intf.c accordingly, adding the line

{USB_DEVICE(0x0bda, 0xa811), .driver_info = RTL8821}, /* Meross AC600 */

and I've recompiled successfully.
After the reboot, I've sent the dmesg command and I see:

[ 87.612786] usb 3-10: USB disconnect, device number 6
[ 89.379497] usb 3-4: new high-speed USB device number 8 using xhci_hcd

[ 89.544038] 8812au: Unknown symbol __vfs_read (err 0)
[ 394.618883] usb 3-2: USB disconnect, device number 2

So everthing seems ok. But the USB wireless adapter is still not visible.
Thanks for the help.

Update 2:
I've been able to modify the code of the realtek-rtl88xxau-dkms file as from your instructions, but the wireless adapter won't start.
So I worked with the software provided by the vendor, and I've been able to compile it. Now the usb adapter starts, and is able to make the internet working. The ifconfig command returns:
