Recent Kernel update 8812au.ko not found

Support & Help Requests

I reloaded the rtl8812au-5.1.5 drivers and the install = no errors but my wifi adapter has 0 function.
I tried installing the adapter drivers from disk for my alfa awuso36ach but get the “8812au.ko not found”

I did get it working again.

sudo apt remove rtl8812au -dkms
cd rtl8812au-5.1.5
make
sudo make install
restart

Would think updates wouldn’t kill something as base as WiFi but I’m a newb.

I’m in a similar situation. I have a different Wi-Fi adapter, but I need to install a driver separately as it’s not part of the Linux kernel yet.

This might happen again on the next kernel update depending whether the rtl8812au-5.1.5 package added DKMS modules. DKMS modules are supposed to rebuild themselves when there’s a new kernel installed, but they can sometimes miss.

It might have been enough to run this next time:

sudo apt install --reinstall rtl8812au-dkms
sudo modprobe rtl8812au                       # Possibly no need to restart

Bear in mind you may need to repeat the same steps again on the next kernel update. Although I wouldn’t recommend installing both the package and the manual make install method.
