No Network access

[ZBM -2]

I'm running Qubes 3.2 on an Asus R541U
My system isn't able to utilize the built in Ethernet and Wifi adapters.
lspci command in sys-net shows both of them.
ifconfig shows lo and vif2.0 interfaces.

I tried to perform "sudo dnf install linux-firmware" as recommended by the user's FAQ and get "Error: Failed to synchronize cache for repo 'updates'"
(by the way, the faq still has yum instead of dnf)
I'm currently trying to find an offline workaround or solution. I would appreciate assistance in that endeavor, or alternately, a heads up that I need to find another tree to bark up.

When I first instaled qubes, I remember using network manager, after that, the applet always appeared on the taskbar.
