Like many i was disapointed to see my awus036ach being listed under lsusb but not recognized as an adapter. The fix was to download and compile https://github.com/aircrack-ng/rtl8812au - something that many struggle with on many ‘underground’ distros as often headers are not included and need to be fetched from rpi-source (with varying degrees of success as you can imagine).
In this case however, as soon as i wrapped my head around the needed symlink (ln -s /usr/src/linux-headers-4.4.38-v7+/arch/arm/ /usr/src/linux-headers-4.4.38-v7+/arch/armv7l for those the curious), install went like a letter in the post and I’m happily kismetting with my cardboard-build, antenna-happy sbc.
Very pleased! Thank you!
