For the Verizon M3100, in the Admin Settings -> Device Preferences screen there are options for Sleep and Shutdown but there is not an option to automatically Reboot or Restart. There should be an option to do this as occasionally the device can get overloaded or hung up and disconnect from cell tower, or freeze up over time and it would be good, especially, if left on for extended periods of time, to automatically refresh or reboot. For example I use this hotspot with my eero device as an internet backup option so if my main ISP goes down this device kicks on and recently the hotspot disconnected randomly from the cell tower and needed to be restarted then it worked fine again.
Summary: Feature Request: Add Reboot or Restart option for M3100 in Device Preferences screen under Settings and allow it to reboot every so often for example every hour, every 6 hours, every 12 hours, every 24 hours as an example or every week or every month, or Never. Provide a list of options or whatever options you recommend.
