Tom, Be sure to upgrade the bios firmware as well when you go to 3.28 You can upgrade the firmware with no loss of config, but to upgrade the bios you have to be in the CLI. System routerboard print (shows you the version you are running with upgrade available) Then type "system routerboard upgrade" and then reboot
We have been experiencing a few odd issues as well.
