Wifi not detected

Support Network
1

Hi, I bought an Asus VivoBook 15 F515JA-BQ926T and installed Manjaro Kde …
Unfortunately it seems that luck does not want to assist me in this period.
Everything works except the wifi network card which cannot detect anything. I can only get it to work with ethernet cable.
Can anyone help me?
Thanks

Highlights from your post:

Network:   Device-1: Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter driver: N/A

It seems the appropriate driver is not installed for you network adapter. I am not familiar with drivers, but I found one in the AUR:

❯ yay -Ss 8821ce
aur/rtl8821ce-dkms-git 1.0.5.r36.gca4abd8-1 (+26 0.01) 
    rtl8821CE driver with firmware

Maybe you can give it a shot by installing the driver:

$ yay -S rtl8821ce-dkms-git

Do what the above post said, but also install linux514-headers first.
