Ethernet through usb-c

I installed Qubes on my computer earlier this year but noticed that the wifi wasn’t working. Since I don’t have an ethernet port I decided to go back to my previous distro. However I really want to go back to Qubes and I’ve purchased an ethernet to to usb-c adapter. A few questions:

  1. Will I get internet by default?
  2. Or do I have to check the box during install that says "Use sys-net qube for both networking and USB devices? I would prefer not to of course for security reasons
  3. I assume that by updating the kernel of Dom0 (if such a thing is possible) I’ll be able to get wifi working eventually? I have the following wifi card: Wireless,CMB,FXN,8822CE M2 but I’m willing to switch it out for another one if that’s what it takes.


Probably related:

I don’t know which one is your, but based on your Wireless,CMB,FXN,8822CE M2, i’ve found:

• Realtek RTL8822CE, 802.11ac Dual Band 2x2 Wi-Fi + Bluetooth 5.0, M.2 card

Some said rtl wifi is unstable, you’d best try with newer kernel and it’s only available by default in qubes 4.1
Kernel 5.4+
Kernel 5.12+ // not signed by qubes team master 

Ok so a little update. I installed Qubes and use sys-net for both networking and USB. USB-C to ethernet works perfectly.

Regarding Wifi, I could see all the Wifi networks but couldn’t connect to them. After updating the system I could now connect but it wouldn’t remember passwords. This seems to have resolved itself after a number of reboots.

I have a question regarding the kernel. When I run uname -r in a dom0 terminal I get as the output:


this is the kernel version right? I find this to be very weird since I installed Qubes 4.0.4 which according to the release notes has kernel 4.9.x?

According to the release notes, this is the correct kernel:

Linux kernel 5.4 by default
