The wireless network is unstable

Installed packages

• dhcpcd
• NetworkManager
• iwd

Solution

• stop and disable service:
  • sudo systemctl stop dhcpcd
  • sudo systemctl disable dhcpcd
  • sudo systemctl stop iwd
  • sudo systemctl disable iwd
• remove package: sudo pacman -R dhcpcd
• reboot

Fundamental problem

The fundamental problem is that dhcpcd conflicts with NetworkManager.
