My guess would be you do not actually have an rtl8812au based adapter (rather another Realtek variant).

Please post:

lsusb

Be sure to restart with your USB Wifi dongle inserted, and no other USB networking devices attached to the computer. This means no phone tethering or USB to Ethernet adapter or other network devices attached to the USB bus when you run the lsusb command.

If the output of the lsusb command returns "0bda:0811" in the chip identification of your realtek device then follow the directions in this post:

after this, sudo modprobe 8811au ive got this error message

modprobe: FATAL: Module 8811au not found in directory /lib/modules/5.6.16-1-MANJARO

Did you actually read this part^^^

You don't actually see 0bda:0811 in your lsusb output do you?

My eyes are poor but I see:

7392:b822

Therefore you did not follow my instructions and for the second time have installed the wrong driver.

Sorry, but I am only on my cell and I have very little patience for helping users who can not follow instructions when I am limited to assiting on a cell phone.
