Wifi problem

My wifi dongle -> https://www.aliexpress.com/item/Rocketek...15976.html
This is a RTL8811AU

Code:

Bus 002 Device 002: ID 0bda:a811 Realtek Semiconductor Corp.

Ok. Let's try again.

• Realtek drivers are chaotic. Only few people has time to make it working.
  
• Do not use https://github.com/sloretz/rtl8811au -> not for 4.x kernel (for example STATION_INFO_SIGNAL is missing in kernel sources...)
  
• Let's try with https://github.com/zebulon2/rtl8812au/tree/v5.1.5
  
  Code:

  $ sudo bash
# git clone --depth 1 https://github.com/zebulon2/rtl8812au.git
# cd rtl8812au
# ### pre-check (0bda:a811)
# grep A811 ./os_dep/linux/usb_intf.c
    {USB_DEVICE(USB_VENDER_ID_REALTEK, 0xA811) , .driver_info = RTL8821},/* Default ID */
    {USB_DEVICE(0x7392, 0xA811), .driver_info = RTL8821}, /* Edimax - Edimax */
    {USB_DEVICE(0x0BDA, 0xA811),.driver_info = RTL8821}, /* Comfast - CF-915AC */
# ### section "#ifdef CONFIG_RTL8821A" so check enabled RTL8821A
# grep "CONFIG_RTL8821A = y" Makefile
CONFIG_RTL8821A = y
# ### Makefile is set for "CONFIG_PLATFORM_I386_PC = y", it is probably ok for generic linux
# ### compile for Rock64, last stable 64bit ayufan image
# uname -a
