Reproduce:
1) Boot the computer.
2) Have no WiFi approximately 5 minutes long.
3) Have WiFi after 5 minutes.

It doesn't matter whether WiFi is tested from gnome or from tty.  My network is configured via interfaces (not via NetworkManager). I have a PCE-AX3000 card and use an up-to-date Debian 11 “Bullseye” with firmware-iwlwifi. The bugs has existed since the fresh installation in January 2021 with all the current kernels so far.

(I don't wish to clutter this bug report with tons of potentially unrelated logs; please advise.)

I don't see a bug in systemd here. What I see are two (maybe related) issues





Regards,

a/ networking-routes.service (from ifupdown-extra) causing a dependency loop (=> looks like a bug in ifupdown-extra to me) b/ an issue with your network configuration (which is managed by ifupdown). If b/ is caused by a/, I dunno. Let's reassign this to ifupdown-extra. Its maintainer will be in a better position to advise you with any ifupdown related issues.
