Does enabling wakeonlan automatically work for you reliably? I tried enabling with cron, but that only works at @reboot . I tried with systemd and other tools as described in https://wiki.archlinux.org/title/Wake-on-LAN and other pages, yet I have to turn it on manually always. The target system runs ubuntu.
In addition to the BIOS settings, I had to create a systemd service that prevents Linux from disabling Wake-on-LAN on shutdown.
