We use both RUT240 and TRB245 in a private closed mobile network with no internet access, thus no access to NTP-server.
After upgrade from legacy to FW 00.07.02.7 (currently 7.03.1), the device time is always 22-12-20 or similar after each nightly reboot. With the legacy FW, the time was correct even after reboot. This means all logs are useless as the date/time is entirely wrong.
I tried to enable sync with mobile - does not seem to work, still wrong date/time.
How can I get the correct date/time in the devices after reboot?
