Hello, I am new with linux and trying my best with one of my laptops. I installed Zorin 18 with no problem but when i get to wifi it connects for a while, then suddenly shuts down and i can not see any networks at all. Scanning but nothing shown. I hav run the "sudo lshw -C network" and this appears:

Hi and welcome.

" The Realtek RTL8821CE WiFi adapter is supported by the native rtw88 kernel module in Linux kernels 5.9 and newer . For older kernels (common in Debian and older Ubuntu LTS versions), you must install the community-maintained rtl8821ce-dkms driver.

Installation Methods

  • For Kernel 5.9+ (Ubuntu 20.10+, Fedora, Arch, etc.): The driver is built-in. If it does not work, you may need to blacklist the conflicting kernel module by adding blacklist rtw88_8821ce to /etc/modprobe.d/blacklist.conf and rebooting.
  • For Older Kernels (Ubuntu 18.04, Debian 10, Linux Mint): Install the DKMS package from the repositories:
sudo apt install rtl8821ce-dkms
sudo reboot
  • Alternative (Source Compilation): Clone the tomaspinho/rtl8821ce GitHub repository and install via DKMS:
sudo apt install bc module-assistant build-essential dkms git
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh
sudo reboot

Common Issues & Fixes

  • Secure Boot: Must be disabled in BIOS/UEFI, or the kernel module will not load.

  • Power Management: Add pcie_aspm=off to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and run sudo update-grub if the adapter disconnects frequently.

  • Bluetooth Conflicts: If Bluetooth fails, disable power saving for the adapter in NetworkManager settings.

Note, Zorin 18 is a fork of Ubuntu 24.04.
