Ideapad Flex 5 - No network devices available

Good day everyone.
My exact device name is Lenovo Ideapad 5-14ALC FHD R5-5.
And as said in in the title I can not use WiFi connections.
I searched for people with the same network card and followed the solutions they had no effect.
I enable the Arch Depositories. Installed the “rtl8821ce” driver. And the kernel headers for my kernel version. Im only confused by this moment, this is my first linux usage.

For this one you will need AUR (en) - rtw89-dkms-git
But first you have to install the linux515-headers
For that you might want to use USB tethering from your phone or something.

I guess you have gone trough this Lenovo IdeaPad Flex 5 14alc05 - ArchWiki

Yes I already installed the “linux515-headers”.
Only had had to install the driver you referred to, thanks for your help.

I used the command:

pamac build rtw89-dkms-git

After a reboot I could finally use my WiFi.
Thank you very much!
