So apparently to fix this issue in Ubuntu 20.04 and later, we need to purgeĪltogether and install the Broadcom STA DKMS driver instead. This should make sure that the proper WiFi module loads when the user logs in and gnome-session starts. Then, add a new a task and set the “Command” field to the path of your bash script. Open the “Startup Applications” from the GNOME shell menu or run gnome-session-properties from a terminal. Mark it as an executable with: chmod +x wifi-fix.sh Open a text editor and write: #!/bin/bashĪnd save it (example: wifi-fix.sh). We can fix that by making a bash script and scheduling it to run on startup.

This will not work on if you’re on a persistent livesystem since you cannot update initramfs due it being a read-only system. Open the file as root with the command: sudo gedit /etc/modprobe.d/nfĪt the end of the file.

You can also prevent the bcma and bcma-pci-bridge drivers from loading altogether by blacklisting them in the /etc/modprobe.d/nf file. Or sudo insmod /lib/modules/5.0.0-23-generic/updates/dkms/wl.ko To remove the bcma and wl modules from the kernel. So, we use the command: sudo modprobe -rv bcma wl But, we need the kernel to use the wl module instead as that’s the one we built while installing the bcmwl-kernel-source package. Subsystem: Hewlett-Packard Company BCM43142 802.11b/g/nĪs we can see, the bcma-pci-bridge driver is in use. You might see something like this: lspci -kĠ4:00.0 Network controller: Broadcom Inc. To check the kernel drivers handling each of our PCI devices. So I looked into the issue again and came up with a better solution. But building the whole module over and over again seemed unnecessary. My initial solution to this was installing the bcmwl-kernel-source package on startup. I figured I’d do the same thing I did on Ubuntu 19.10, as mentioned in one of my previous posts. usr/lib/modules/$(uname -r)/kernel/drivers/net/wireless/8821ce.After installing Ubuntu 18.04.3 LTS on a persistent live system, I noticed that the Wi-Fi would stop working on every reboot. Sign the 8821ce.ko file yourself as per command given here kmodsign sha512 \ You also want to make sure SecureBoot is Disabled in the BIOS settings or it won't let you load the unsigned self-complied kernel module. Open up a terminal and type the following lines (You can cut and paste if you prefer): sudo apt-get install -reinstall git dkms build-essential linux-headers-$(uname -r)Īfter this is completed successfully, you should reboot and find that your Wifi is working. The solution is taken directly from post #4 by Praseodym: and will install a number of packages for building the wifi driver module (git, dkms, build-essential & linux-headers) and clone the git repository from tomaspinho.ĭKMS is used because it's "a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated." It has, however, been reported to work just fine with Ubuntu 18.04. (Minor note: as of February 2019 tomaspinho is sadly no longer able to maintain the driver as he no longer has access to a computer with this chipset, and so a new maintainer may be needed, but the driver still works with Ubuntu 18.04 as at that time.) Over on github there is a repository with an RTL8821CE driver aimed at kernels 4.14 and above and specifically for Arch Linux with no support provided for other Linux Distros:

(This question is a duplicate of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) but I was pleased that we eventually found a solution so will write up what worked for Haz.)Īs far as I can tell, at the time of writing this, there is not yet a Wifi Driver for the Realtek RTL8821CE in the official Ubuntu Repositories.
