Post Installation

Fix WiFi adapter not recognized issue

Use lspci -k to show drivers in use.

Find the Wi-Fi adapter (most likely the Broadcom one)

If the kernel driver in use is either bcma-pci-bridge or b43-pci-bridge, I need this process

procedure

• sudo pacman-mirrors -f 5 && sudo pacman -Syyu to update system
• sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ') to install Linux headers packages
• sudo pacman -S dkms
• sudo pacman -S broadcom-wl-dkms
• reboot!

Connect to WiFi (with iwd)

• sudo pacman -S iwd
• sudo systemctl start iwd.service
• sudo systemctl enable iwd.service

Enter iwctl to get in to the interface Use device list to see WiFi adapters available station {device} scan to scan networks station {device} get-networks to see available ones station {device} connect {network} to connect!

Connect to WiFi (with NetworkManager)

• sudo pacman -S networkmanager
• sudo systemctl start NetworkManager
• sudo systemctl enable NetworkManager
• nmcli dev wifi list to show every Wi-Fi available
• nmcli dev wifi con "{SSID}" password "{password}"
• try enabling/starting wpa_supplicant as well if it didn’t work!

Boot option doesn’t show up (on Mac)

Always check this ref: https://wiki.archlinux.org/title/Mac First, inside chrooted environment, run bootctl --path=/boot install

We’ll modify files in /boot/loader/ change loader.conf content to

    default arch.conf
    timeout 4
    console-mode max
    editor no

add two files (arch.conf, arch-fallback.conf) under /boot/loader/entries/

• arch.conf

      title Arch Linux
      linux /vmlinuz-linux
      initrd /initramfs-linux.img
      options root="UUID={UUID}" rw
  

• arch-fallback.conf (*optional)

      title Arch Linux (fallback initramfs)
      linux /vmlinuz-linux
      initrd /initramfs-linuz-fallback.img
      options root="UUID={UUID}" rw
