Lenovo Legion 7i Realtek c852 PCI device dom0 does not exist sys-net fails start

User Support Hardware Issues
1

New install of Qubes os went well after turning off secure boot but the Realtek Wifi card c852 is not recognized in sys-net.

The Wifi is recognized in dom0 but sys-net gives error pci device 73:00 does not exist when starting the sys-net VM.

There is no Ethernet port so no networking without the Wifi card working.

Update is that rmoving the failing Realtek PCI WiFi adapter and using a Realtek USB network adapter works after adding it to the sys-net vm.

Here is my hardware report of the Lenovo Legion 7i laptop.

Video, sound and track pad all work so far. Just the Realtek WiFi card is not working.

Now that there is internet connectivity a solution can be found for the WiFi driver issue.

Any help is appreciated.

I have the same exact same problem as you.

This is my network card: (output redacted)

[root@dom0 firmware]# lspci -nnv

But is not detected by qvm-pci:

So I can’t attach the network device to any VM with qvm-pci, including to sys-net.

I would appreciate any help

Same problem (also Lenovo Legion): Network controller detected in lspci but bot in qvm-pci.

Everything worked fine for a while until I now booted to the error message that the device does not exist.
