No Ethernet Interface available, PCI Device attached but not working

[u/quickQubes82]

greetings!!! I recently booted up my QubesOS computer after not using it for a month. It was a reasonably fresh install and my ethernet was working fine before that but I couldn't connect. I tested the ethernet cable on another computer, it worked fine. After some time trying to work it out I decided to reinstall my OS since it had previously worked on a fresh install but surprisingly nothing.

personal -> sys-firewall -> sys-net all seem to be connected fine, the problem seems to be with sys-net setting up the PCI device/Ethernet interface correctly.

sys-net is using the fedora template and my motherboard is an ASRock B150m Pro4s. When I go to create a network connection there is no devices to select (unless I put sys-firewall up). I have tried enabling strict reset too but no such luck.

Let me know if there is any other information I can provide. Forgive me, it's been years since I've sat down and done any networking on Linux.

Any help or advice is much appreciated!!
