Hi, KitchM <kitchm@tutanota.com> (2025-06-25): > There is a conflict in comparing the installer's methods to the Debian > standards when it comes to the network configuration.

Having tested all desktop choices on Debian 12 (including no desktop), I'm pretty certain there's no connectivity issue in any of them, be it with ifupdown or NM. If things don't work, you really should mention details, ideally attaching logs. You didn't do that. We cannot do anything about your being unhappy with the fact there's no systemd-networkd/netplan in the picture. Closing accordingly as not actionable.
