Creating a software AP (wifi hotspot) works in Windows 10 but fails silently in Linux.

Steps taken to try to resolve

  • Rebooting
  • $ create_ap --stop wlp5s0
  • Unmanaging wlp5s0 in NetworkManager
  • installed create_ap-git from Arch linux AUR

These all result in a silent failure.

$ create_ap wlp5s0 enp4s0 a4
