Re: WIFI not working

Start with Wireless#Check_the_driver_status.  Also what commands did you use to produce the outputs you posted?  Please post commands and their outputs in code tags.

Hi, thanks for your reply

It seems like the firmware isnt being loaded in.

Re: WIFI not working

Previously I used Brunch ChromeOS, and had wifi working. So I am certain that the drivers/firmware exist for Linux.


It seems like the drivers are already included in the Linux kernel (https://wireless.wiki.kernel.org/en/use … rs/rtl819x), same goes for the Bluetooth drivers which arent currently working aswell.

Exactly.
Driver != firmware.
With that in mind, please re-read https://wiki.archlinux.org/index.php/Ne … r/firmware

Re: WIFI not working

pacman -Qo /usr/lib/firmware/rtlwifi/rtl8723befw_36.bin
/usr/lib/firmware/rtlwifi/rtl8723befw_36.bin is owned by linux-firmware 20200721.2b823fc-1

Installation_guide#Install_essential_packages

Use the pacstrap(8) script to install the base package, Linux kernel and firmware for common hardware:

# pacstrap /mnt base linux linux-firmware

Tip:

  • You can substitute linux for a kernel package of your choice, or you could omit it entirely when installing in a container.

  • You could omit the installation of the firmware package when installing in a virtual machine or container.

I feel so dumb right now, I only did base, Linux and Linux-headers
