RTL8812AU not working after kernel upgrade #1169

After upgrading machine I cant get the RTL8812AU adapter to work anymore. The adapter is visible but not seeing any networks.

any solution?

Currently experiencing the same issue on Kali. Attempted to roll back the kernel as a solution but didn't work, due to linux header files not being pulled directly.

I've tried some other drivers for this, but they do not support monitor mode. They'll detect networks perfectly fine as a managed interface but beyond that won't work.

Hi you two, had the same issue, was able to fix it using instructions from a few issues below ("USB Wifi TP-Link AC600 cannot work with newest version").
