Do you have a qca9377 wifi adapter:

inxi -Fxxxz

If so you need to update your firmware I will post a link if your adapter is listed in the command output.

I’m a newbie. I’m still learning linux with manjaro.

To fix the incorrect firmware for the QCA9377 adapter:

If you have another internet connection on your computer such as wired LAN then simply issue the following command in the terminal:

sudo pacman -U https://manjaro.moson.eu/pool/overlay/linux-firmware-20181026.1cb4e51-0.1-any.pkg.tar.xz

If you don’t have a wired connection then use this alternate method. Download the following file, and copy it to your home directory. You can use phone tethering , or copy it from a thumb drive to home.

https://manjaro.moson.eu/pool/overlay/linux-firmware-20181026.1cb4e51-0.1-any.pkg.tar.xz

Once the file is copied to your home directory, in the terminal cd to your home directory.

Then, issue this command:

sudo pacman -U ~/linux-firmware-20181026.1cb4e51-0.1-any.pkg.tar.xz

Then confirm the install in pacman, and reboot.

BTW, this exact same issue has been posted at least a half dozen times in the last day. Please search the forum before you post a help request, as the answer has usually been posted multiple times before.

Let us know if that fixed you up. Also you can remove the soft block on your bluetooth with the following command:

sudo rfkill unblock all
