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.

I think that line indicates that the driver is detecting and handling your wifi card. If it's not working well, that's unfortunate because no one is going to fix it.

The problem you have with rtw88 may have been fixed already. Depends what the problem is. You can try a newer version of it: https://github.com/lwfinger/rtw88/
