With some flexible value of "tomorrow", it seems I can conclude the problem is rather on the kernel side than on the userland side. It isn't too surprising since I had already tested downgrading netcfg and wpa to wheezy's versions, and that didn't help. My cross tests were done using: - wheezy or sid as a basis times: - 3.2 or 3.16 linux udebs building a netboot-gtk image in the appropriate chroot (wheezy or sid). I also included all the firmware files included in the firmware-realtek package from wheezy (for 3.2) or from sid (for 3.16) to take that out of the picture. End results: - wheezy and sid with 3.2 work - wheezy and sid with 3.16 don't work (card recognized, scanning OK but association KO). I've also checked that installing sid + 3.16 over Ethernet then manually connecting (wpa_passphrase then wpa_supplicant) worked just fine (that's been mentioned in my previous mail, but confirming). I'll now try and compare dmesg from within d-i and from the installed system to see whether I can spot some differences which could help me understand what the differences are, and possibly ask kernel maintainers for help/insight.
