if it's a VM, are you sure the mt7615 is exposed correctly towards openwrt ... ?
if you boot openwrt from an USB flash drive, on the same HW, does the radio work ?
I believe it is correctly passed through as the host is now using the vfio-pci drivers rather than the mediatec one
this is the output from lspci -v on the host

and this is how it is listed in the vm

I did not try yet with a usb flash drive. Hopefully there are some other things to explore first before I have to take that system offline as it will disturb the users
I have a new lead.
daemon.notice netifd: radio0 (6671): ls: /sys/class/ieee80211: No such file or directory
after digging online somehow compat-wireless is missing. digging more I checked if I had kmod-mac80211 installed but it is. maybe reinstall that?
Can I try something else?
