Installed OK bot no Wifi Card Detected

[matiasgatti]

Hi, I had a new Laptop Asus Vivobook 15. Installed Ubuntu 24.04 and wifi works bad: I got disconnections and errors of all kind. So, I decided to install RTL8821CE, installation went OK. But can get wifi card work with this driver: if I blacklist rtw88_8821ce in /etc/modprobe.d/blacklist.conf wifi card is not detected.

Info:

If I remove "blacklist rtw88_8821ce" I have wifi with kernel driver. But got a lot of errors/disconnetions.
