After install Qubes have some issue with sys-net, network not working.
Finding some information on https://www.qubes-os.org/doc/assigning-devices/
In dom0 come to root and add
echo -n "1" > /sys/bus/pci/devices/0000:04:00.0/remove solved the problem,
but after reboot laptop this settings are reset.
My network card is Qualcomm Atheros QCA9377 Wireless Network Adapter and Realtek PCIe GBE Family Controller.
How to make sys-net normal work correctly?
