FENVI WiFi 6 Adapter AX286 (AICSemi AIC8800DC) #680
Description
Introduction
I bought this FENVI WiFi 6 AX286 Adapter from the FENVI Aliexpress Store: https://www.aliexpress.com/item/1005005698160651.html
I thought I'd give it a Try since it was quite cheap for a WiFi 6 Device.
It is one of these "Driver-Free" WiFi Adapters, so that was the first Obstacle to solve.
Initial Identification
Connecting the Device shows the following in dmesg -T:

But this is just the Storage Device (roughly 8 MiB Storage Device).
Ejecting the USB Storage Device
Turns out somebody already had to deal with it somehow (but I still post it here, since @morrownr is the Reference for WiFi Adapters on Linux 😉) and they gave some Recommendations on how to eject the Storage Adapter, which will then expose the Network Adapter.
Eject the USB Storage Adapter:

Further Steps
Based on the above linked LinuxMint Forum Thread, it seems that one has to go forward and install the Kernel Drivers via dkms from a GitHub Repository.

Looking around, I found this Gentoo ebuild File:
https://gitweb.gentoo.org/repo/gentoo.git/tree/net-wireless/aic8800/aic8800-1.0.6.ebuild
Which hints at the Location of a DKMS File for Debian:

This contains the Firmware, Kernel Module Source Code and some Udev Rules:
