How I Fixed the Alfa rtl88xxau Driver on Linux Kernel 6.15, 6.16 and 6.18
If you do wireless penetration testing on Kali Linux you have probably run into this at some point. You update your system, reboot, plug in your Alfa adapter and nothing works. Airodump-ng throws errors, wifite cannot find your interface and monitor mode is completely broken. That is exactly what happened to me and it took a while to figure out why. The problem is not your adapter. The problem is that the Linux kernel keeps evolving and the open source rtl88xxau driver that powers most Alfa adapters has not kept up. Three separate kernel API changes across versions 6.15, 6.16 and 6.18 broke the driver source code in different ways. Unless you know exactly what changed and where, you are stuck staring at a wall of compiler errors with no obvious fix. I went through the kernel changelogs, read the build errors line by line and figured out what needed to change. Then I wrote a bash script that automates the entire fix so you never have to do it manually. Why the Driver Breaks To...
