Thanks a lot for the feedback. As my solution works quite well - except for the Wifi issues, I would like to dig a bit deeper here.
The following would help me:
Does anyone have a clue, how to
- autostart the browser in fullscreen mode on reboot? (what is the console command?)
- automatically set the orientation to inverted_landscape on reboot?(what is the console command?)

Then I would simply reboot, when the issues occur. This usually helps.

Many thanks in advance.
