Hello,

 

I tried to install the RTL8821CE card on Orange Pi 5 Plus, but only the Bluetooth is on, the wifi not working. Which driver i should use?

 

I am using Armbian 24.2.1 Jammy with Linux 5.10.160-legacy-rk35xx

 

here is the dmesg of

You might wanna bump the kernel for more modern support, but check to see if the drivers are blacklisted within /etc/modprobe - see various comments in
