The kernel log is repeated.  The next log line is again scanning start,
since NetworkManager (or wpa_supplicant, I'm not familiar with the machinery
involved) request scan again.

Can you give some more specific comments please?  We just rebooted the
AP the next time, it all started working again, and I need to install
all the necessary tools while it is working ;)  Since I'm not familiar
with wifi machinery, maybe you can give me specific command lines to
run? :)

Thank you!
