This method pretty much works with all arch distros for those individuals unfortunate enough to choose computers that include Broadcom wifi.
First, since 5x kernel’s , some arch distros that previously needed wifi installed post os-install, seem to work without doing so. I’m not sure which one’s.
BEFORE installing or trying live usb of an arch distro!
(rolling release, so that means minutes before)
- go to /www.archlinux.org/packages/
- download latest linux-headers package onto usb separate from iso.
- download latest dkms package onto usb separate from iso.
- download latest broadcom-wl-dkms onto usb separate from iso.
Reboot into live USB ISO or perform install of arch distro (Endeavour OS)
- with your driver USB files inserted either cd to or enter path to drivers in following commands in order listed.
sudo pacman -U dkms
sudo pacman -U linux-headers
sudo pacman -U broadcom
sudo modprobe wl
sudo depmod -a
- Wait a few moments then connect to your wifi network if live USB.
- If a new install, wait a minute if the system doesn’t find wifi network within 5 minutes reboot to a working wifi connection.
