No network after install

Alright mister genius… I tried your commands and nothing happened
but I restarted and here I am writing to you on qubes. Finally!

Makes sense, sorry I forgot to mention the reboot. Glad you figured it out!

Would you happen to know what is this second NIC on my menu?

I’m pretty sure ‘vif’ stands for virtual interface. There must be one in
sys-net: the PCI device is your connection to the outside, the virtual
interface is how e.g. sys-firewall connects to sys-net.

I don’t know why it’s showing up in your network manager, maybe someone
else here does.
