Ethernet through usb-c

ryuu · June 25, 2021, 3:44pm

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:

Will I get internet by default?
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
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.

thanks!

**The problem you're addressing (if any)** I have a "TP-LINK Archer T4UH V2" US…B WLAN adapter ("AC1300-High-Gain-Dualband-USB-WLAN-Adapter"). There exists a working Linux driver for it, but most Linux distributions do not include it (The driver supplied by TP-LINK does not even compile in current kernels). What works in almost every Linux distribution is "USB tethering" using my Android mobile phone, however. Qubes OS detects the USB WLAN device too, but I cannot use it for networking: It's not listed in the USB device list used to assign to a VM. **Describe the solution you'd like** I'd like to be able to use USB tethering, maybe by providing an alternate `sys-net` VM, but preferrably by using the virtual USB adapter in the standard `sys-net` VM. **Where is the value to a user, and who might that user be?** The user could use (wireless) networking when otherwise it would not work. **Describe alternatives you've considered** Buy a WLAN repeater with Ethernet cable connection, and connect computer with repeater. **Additional context** _Add any other context or screenshots about the feature request here._ **Relevant [documentation](https://www.qubes-os.org/doc/) you've consulted** _A list of links to the Qubes documentation (or other relevant software documentation) pages you have already consulted._ **Related, [non-duplicate](https://www.qubes-os.org/doc/reporting-bugs/#new-issues-should-not-be-duplicates-of-existing-issues) issues** https://github.com/QubesOS/qubes-issues/issues/2680

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

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:

5.4.129-1.fc25.qubes.x86_64

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
