wow
very very good and thank you a lot
why i not find this excellent HowTo in Internet..
now i understand also why is not overwriting after i change networksettings
One question more please
I need some different networksettings for different arduino boards
is much more easy for my i safe my changed NetworkSettings but i can not because 1) is write protected and 2) i not find this file and can not change the permissions there
because maybe i installed via
Boards Manager Installation
and i use
