I've just installed Proxmox on my new Intel NUC8i5BEH and it is working quite well. However my NUC's build in Wifi is not visible and I wish to use this for the Virtual Machines on it. Is that possible? The chipset is called Intel® Wireless-AC 9560. I'm not very experienced with Linux so I bear with me. I found an old topic about it, but instead of resurrecting that one I created a new one. That topic though something about a "non-free" repository was mentioned. Where do i find these? I know how to add them to sources.list, but not sure what it means exactly
