Ok, so we are one step further, some days ago I installed a cron job (chekc.sh) done every 5 min to ping the router and if ping fails, restart networkmanager as given in the last post.
After some 30 h uptime (without accessing the motion stream od ssh) the network apparently fails, but the restart of the netmanager fails, too:
For this
the only thing I could find is this
viewtopic.php?t=371789
...which is not very helpful.
So apparently WLAN0 fails after 24+h of no activity and a restart fails also.
Could try a reboot on WLAN0 fail, but would like to learn what's going on here.
