No Network devices available

Hello...

I'm completely new to Manjaro and I tried installing Manjaro Linux on my laptop. After installing Manjaro XFCE, I couldn't connect to the wifi, it says 'No network devices available'. I tried switching the kernel but the one I'm currently using showed up. I also typed 'rfkill list' on the terminal but the only thing that showed up was

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

Please help..

Please post

inxi -Fxxxz

If you can not see the grub boot menu to switch kernels, then press the ESC key every second or so after booting until it appears.

inxi -Fxxxz result(I don't know how to post the command...):

Follow the guide I posted above for Apple and Broadcom installs.

I would recommend kernel 5.0 along with the broadcom-wl-dkms driver and the Linux headers for that kernel.

I tried following the guide but when I type the commands I get warnings and errors. It tells me to use -Sy after pacman, but it doesn't work as well...

You must post all inputs and all outputs if you want assistance. Generalizations and summaries are useless on remote assistance requests. Go through the procedure as outlined on that guide again and post every INPUT as well as every OUTPUT.

Please install kernel 5.0 as well as the Linux headers and switch to kernel 5.0 to perform the driver install.

You need to substitute the version number that you have installed in any command in that tutorial. That guide was written when kernel 4.14 was the default. I can not possibly anticipate which kernel you have installed in a guide written in advance. You need to use a bit of deductive reasoning to have the commands work.

I'm not sure how to install kernel 5.0 and Linux headers.

I substituted the kernel number:4.19

INPUT: sudo pacman -Rns linux419-broadcom-wl

Output:
warning: database file for 'core' does not exist (use '-Sy' to download)
warning: database file for 'extra' does not exist (use '-Sy' to download)
warning: database file for 'community' does not exist (use '-Sy' to download)
warning: database file for 'multilib' does not exist (use '-Sy' to download)
error: target not found: linux419-broadcom-wl

sudo pacman-mirrors -f 10 && sudo pacman -Syyu

Install kernel 5.0 before you go any further if you have not already. You can install the kernel through Manjaro Settings Manager. You must boot into kernel 5.0 before you install the headers. Run this command to install the linux headers for all installed kernels.

sudo pamac install $(ls /boot | awk -F "-" '/^linux/ { print $1"-headers" }')

Try these commands again once you have booted into kernel 5.0.

I got errors for both commands:

INPUT: sudo pacman-mirrors -f 10 && sudo pacman -Syyu

OUTPUT:
error: failed retrieving file 'multilib.db' from (website)
error: failed retrieving file 'community.db' from (website)
error: failed retrieving file 'extra.db' from (website)
error: failed retrieving file 'core.db' from (website)

INPUT: sudo pamac install $(ls /boot | awk -F "-" '/^linux/ { print $1"-headers" }')
OUTPUT:
Failed to get connection to xfconfd: Error spawning command line

Which country/region are you in I will manually select the servers by country.

I'm in Hong Kong

Try this.

sudo pacman-mirrors -c China && sudo pacman -Syyu

I am having a difficult time with posting commands because I'm on a cell phone and the spellchecker is playing havoc with the syntax I type.

I don't think it worked... I still got the same error messages...

Try Indonesia instead.

sudo pacman-mirrors -c Indonesia

If that worked then:

sudo pacman -Syy
sudo pacman -Syu

I got the following outputs:

INFO Internet connection appears to be down
INFO Mirror ranking is not available
INFO Mirror list is generated using random method
INFO User generated mirror list

INFO Custom mirror file saved: /var/lib/pacman-mirrors/custom-mirrors.json

INFO Mirror list generated and saved to : /etc/pacman.d/mirrorlist
INFO To reset custom mirrorlist 'sudo pacman-mirrors -id'
INFO To remove custom config run 'sudo pacman-mirrors -c all'

I tried these two commands:
INPUT: sudo pacman -Syy
OUTPUT:
error: failed retrieving file 'core.db' from (website)
error: failed retrieving file 'extra.db' from (website)
error: failed retrieving file 'community.db' from (website)
error: failed retrieving file 'multilib.db' from (website)

INPUT:sudo pacman -Syu
OUTPUT:
error: failed retrieving file 'core.db' from (website)
error: failed retrieving file 'extra.db' from (website)
error: failed retrieving file 'community.db' from (website)
error: failed retrieving file 'multilib.db' from (website)

Sorry from my cell I'm pretty limited in that I don't have the resources available that I would at home. Hopefully some one will pipe in on the next step for you to take. I'm not sure where to go from here. I thought changing the mirrors would resolve the errors.
