It seems that for IWD 1.27 and maybe also later roaming is completely > broken (at least for brcmfmac). It does not connect (No suitable BSSes found) or 'brcmfmac' -> Full MAC. Full MAC implies that all roaming is handled by the firmware and iwd is not (or hardly?) involved in roaming with such setups. > it connects but with wrong AP (poorer access point) or it just looses connection > and does not re-connect (maybe even blacklists somehow wrong). I have also found Reconnecting we can maybe fix. Do you have logs? > several related issues [1,2] and also there are related change logs for IWD in > several versions, up to 2.22 [3]. > 3. Build IWD 2.22 from source (maybe using Debian sid source package?) -> how to > do best and will this work with libc6 version 2.36? Missing libreadline8t64? I mean this is your only real solution. There is no 'long term support' model for iwd. You either run the latest or you're on your own. It is highly unlikely that any of the developers will look at logs (or attempt to fix) anything but the latest version. Regards, -Denis
