RTL8821CE WiFi adapter - Screen freezes when connecting to wifi

Updates: screen continue to freeze, but i found another solution.

Install this driver:

https://aur.archlinux.org/packages/rtl8821ce-dkms-git/

I went to /etc/modprobe.d/ and create a file blacklist.conf.
Into that file i wrote:
blacklist rtw88_8821ce, blacklisting the default wifi driver that comes by default with the kernel.

Then /etc/default/grub and added pci=noaer at the end of the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rd.udev.log_priority=3 vt.global_cursor_default=0 systemd.unified_cgroup_hierarchy=1 loglevel=3 pci=noaer"

Then do sudo update-grub and reboot.

Screen does not freeze anymore :smiley:

And finally went to:
Advanced network configuration -> selected my wifi -> setting (bottom-left) -> set band to 2.4GHz.

Went from 1MB/s to 13MB/s

Hope this post will help someone else. :v:
