@Virgo The point is that the firmware indicate that the configuration has changed even is nobody has touched anything. The firmware indicate that something has has been changed, but no details.

  @PerHe I have come to just accept this as normal. On all of my CPE710 units, I hit apply, it reloads the page, and then prompts me to save changes. I hit save and move on.

Is yours always showing save or can you click save and it stops until you make another change and apply?

  @RickJamesBish I wouldn't complain about change-notification if I make changes. That is how things are supposed to work. The problem is that the device indicate that changes have been made although I'm certain nothing has changed. If the device can't keep track of changes how can I then trust it to keep doing what I have configured it to? There is also the issue of the CPE's requiring reboot every now and then which adds suspicion wrt the integrity of either the firmware or RAM ... or both. I doubt it is hardware as the problem applies to all CPE's. Probably a software issue. Could for example be corrupted pointers messing up the running config. That could trip change-detection and cause a failure that require reboot. That is impossible to truoubleshoot when there is no event-logging implemented (except from logging boot-time and IP-address set during boot). I need devices that I can trust so I'm looking for a more reliable alternative. 

  @PerHe its a long shot but check your time settings under system tab. Make sure timezone is correct and sync with PC clock.
