Sad 😢. I am using Unraid for my backup system, which is not always on. I do not want to waste a port on my router, as I need every single one. The system is slow and has only SATA2. So network speed won't be an issue. It would have been awesome to place the system anywhere in the house, where there is power.
I bought the Asus USB-AX55 Nano with Relatek RTL8852BU.
Theoretically it should be possible to add a driver, as there is a community plugin, which adds a driver for other Realtek network adapters.
Luckily, I just wanted to test Unraid over Wifi. The USB adapter will go into my other Windows PC, which has no Wifi built in.
