Realtek is known for its ignorance of Linux and I cannot find the RTL8822BE
in the AUR, so please read this:
Especially the Linux has multiple kernels section, then try the latest delelopment kernel and hopefully the problem will go away “automagically”.
Please note that you’re on the Development bandwagon and the “Stable” kernels are less stable than LTS kernels.
