Installing network drivers

User Support General
1

My qubes installation was successful but the setup failed at the setup networking part. I tried to disable the network card in the bios and tried a new installation but with the same result. I want to try to install the network drivers next and I know I have to install the drivers in the sys-net qube. But I don’t have a sys net qube. When i i boot thr os after the failed setup I have no qubes at all only templates. Even the default user qubes are not there. So what can I do now?

By the way i don’t have a regular network card but a wifi6 antenna I connect at the back to my mainboard

the drivers must be install in the template of your sys-net.
i don’t know what is “wifi6 antenna” it’s connecting in usb or it is a pci card ? :confused:

A wild guess from me, would be a motherboard like:
https://www.gigabyte.com/Motherboard/B850-GAMING-WIFI6-rev-1x

where the back looks like:

In post installation process, what you choose in sys-net and sys-usb related options? did you set to merge sys-net into sys-usb?

may you share output of lspci and lsusb commands? (run at dom0 terminal)

p.s.
Try to run also:

lspci | grep network
lspci | grep wifi
lspci | grep 2T2R
lspci | grep Ethernet

Exactly! I connect the antenna in the WiFi port. I did some troubleshooting in the meantime and I got a working installation with the sys qubes except the sys-usb qube. I can not start it because of PCI Device dom0:0b_0 0.0 does not exist. For some reason my keyboard and mouse work without the manual approval at the start.

I just checked the website from my main board manufacturer and I saw there are no Linux drivers for internet. There are no linux driver at all. For windows there are drivers for every device on my mainboard. I wrote them an e-mail and asked for support.

It’s a dilemma. When I do the regular installation networking is working but only with 50kb/s. But I can only boot when I enter the nomodeset in the grub config else the boot process stops at plymouth-wait-quit.service and I’m stuck there. But the nomodeset setting is going to reduce my GPU functionality to a minimum. I need my GPU.

When I install qubes with the newest kernel option everything boots fine but the setup freezes at setup networking. After a reboot I am again in the setup dialogue and I can finish the setup without networking set up.

I already checked the docs and various forum posts but I don’t know what to try next.

Unfortunately I can not attach a USB drive to my computer and also have no internet in that PC.

But I type it here:

lspci | grep wifi no output
lspci | grep 2T2R no output
lspci | grep Networking - Network controller: Realtek Semiconductor co.
lspci | grep Ethernet Network controller: Realtek Semiconductor co.

These two were the only network related entry’s. All other entrys are Advanced micro devices and some Nvidia Corporation Device

They directly connected to dom0 if sys-usb not running.

May you run live-cd of fedora 41 to check if it support your hardware from box?

I tried first to change the net-vm template to Debian 12. Same result like the fedora template no wifi.

I created 2 live usb drives with Debian 12 and fedora 42. Both networking work fine. I checked the internet by installing something from the package manager and it was fast as it should be.

I think it has to be something more fundamental. Maybe it has nothing to do with the network card because the setup stucks at setup networking no matter if i have the network card enables in bios or not.

You using 4.2.4?
If so, try to install 4.3.0rc1 on your device
