Unable to connect to wifi in laptop

I cannot connect to wifi in my lenovo ideapad 330{AMD Ryzen 5 and Radeon Graphics}; it shows "no wifi adapter found". Manjaro is the only system that is installed. I need some help, I am new to Manjaro and Linux.

I am also having same issue but no one is helping.whats the use of this os when it does not even show basic wifi connectivity? I am better switching to ubuntu or knoppix or mx linux which shows flawless wifi connectivity even on live usb pen drive

The following command will automatically generate a blacklist file with the correct entries.

echo "blacklist ideapad_laptop" | sudo tee  /etc/modprobe.d/blacklist_ideapad_laptop.conf

Reboot.

I had the same issue in Ubuntu well.

Okay. What should I include for this question?:slightly_smiling_face:

Sharing inxi -Fxxxz --no-host from terminal would be a good start.

I have this same exact wifi device in my asus. It does not work straight out of the install you need to download the rtl8821ce-dkms-git from the AUR. After it is has been installed reboot the computer and you should see the list of wifi connections when click on the network icon in the system tray. You can either download this using the terminal with yay -S rtl8821ce-dkms-git or you can enbable the AUR in you software manager under preferences and just install it from there.

In addition to the drivers from the AUR you must also install the linux-headers for your kernel version (before driver installation).

Okay. I will do that and post what happens. Thanks.

Would you please explain the same?
