It didn't work.
So I went to restore everything ready to give up, and I noticed that the channel was again Auto instead of the 36 I selected before reboot.
So I reset everything to auto and tried again the channel on 36 and I am happy to report that you were right.
That channel worked, and some settings are not really saved.
Should I care about not having it in auto mode?
Or only if I notice performance issues?
