I believe the correct command is → sudo modprobe rtl8821ce
instead of → sudo modprobe 8821ce
Nope, it’s sudo modprobe 8821ce
Yes, I should make a backup of net-system first. I’ll do that next time, but So far anytime I make a change and it doesn’t work, I undo the change. If there is a change I can’t undo, I just re-install everything.
I still can’t get the RTL8821ce driver to work. Here’s what I’ve tried so far:
New Dell Inspiron 3520 laptop
Install Qubes
Debian desktop
Try to start sys-net, fails, remove rtl8821ce as a device, restart, starts
Start sys-usb, enable USB tethering to get Internet
Created new sys-net-perm as StandaloneVM
Sudo apt-get update
Sudo apt install -y dkms git
Git clone https://github/com/tomaspinho/rtl8821ce.git
sudo apt install bc module-assistant build-essential dkms
sudo m-a prepare
Disconnect usb tethering
Sudo Chmod +x dkms-install.sh
Sudo ./dkms-install.sh
sudo modprobe 8821ce
Other Things tried:
blacklisted other driver, by creating file /etc/modprobe.d/blacklist.conf
with content blacklist rtw88_8821ce
sudo $EDITOR /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pcie_aspm=off”
Sudo update-grub
Tried changing sys-net qube to PV and PVH from HVM
Set init-memory to 825MB from 425MB
Given what you’ve done, have you checked the WiFi card with Ubuntu or some other OS to ensure it is not an equipment issue? It’s only happened to me once - a DOA WiFi card - but it does happen.
The Dell laptop came installed with Windows and the wireless driver worked great with Windows. No, I haven’t tried it with another OS…just Windows and Qubes.
This sounds quite similar to when I tried an Intel BE200 WiFi7 card. (1) I learned the proper driver wasn’t in Debian, so I used Fedora in sys-net and sys-net booted. It wasn’t stable however, with my connection cashing within a few minutes. (2) A kernel issue was found preventing the BE200 from working properly, so I tried the updated kernel and it still didn’t work.
In addition, my system wouldn’t boot at all when updating from kernel 6.6.42 to 6.6.48 because of a nouveau kernel change (latest & LTS). Though this was quickly corrected in the Linux kernel, but not fixed until a few Qubes kernel updates later (6.6.63).
So, if you have tried Fedora as sys-net and a different kernel didn’t help I would purchase an NVMe Intel AX210, replace the rtl8821ce, and be done with it (that’s how I quickly fixed my BE200 “update”).
I appreciate the hints.
BTW, I’m a quantum guy, too. I even wrote a book on it.
I was looking for a book on that topic. I’ll buy one. Thanks for the info!
I also thought it would be good to go back to the beginning and am currently reading Dirac’s Lectures on Quantum Mechanics.
