I’ll make a new thread for that as the Realtek 8852AE is quite common. This WiFi-Module is not supported by any kernel yet and will not before 5.15.
The problem is that the available driver (rtw89) doesnt work in a VM and subsequently sys-net. Fedora 34 and Debian 10 tested, same result. qrexec cant connect anymore. Logs say qrexec (db agent and xen driver daemon) “failed” but no helpful informations why. There are no errors while compile or install. Everything done in sys-net’s TemplateVM. Funnily compiled/installed in sys-net I get the driver shown with lspci but could get it working either.
