Hi, thanks for your help, unfortunately this also did not lead to success. The main problem is still when I alone changes to the network e.g. assignment of a fixed IP address, then this is not saved, the process is not completed at all. In the syslog I have searched after a restart times for "error" and found some errors. I share these errors here again in the forum.
