dhcpcd "carrier acquired" when wpa_supplicant stopped

za flag

A system I am working on was based on Debian Buster (via Raspberry Pi OS).

I could shut down Wi-Fi by stopping wpa_supplicant, and it worked fine.

I have now updated my system to be based on Debian Bullseye, and things aren't working right any more.

Specifically - when wpa_supplicant finishes closing down, dhcpcd is reporting "carrier acquired" (it would already have seen "carrier lost" at this point) and rebinds the lease for wlan0, essentially trying to start Wi-Fi up again.

As far as I can see, a message from the kernel (which wasn't there before) is stimulating dhcpcd into this course of action... Anyone have any ideas why the kernel is behaving differently to before, i.e. between Buster and Bullseye?

Thanks, Richard.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
