FYI:  I of course followed the instructions to upgrade the OS to v6.1 before I did anything.  However, when I clicked on "RouterBoard" in WinBox, I found that I was running firmware (which is of course "different") v3.02, and v3.12 was available.  I did the upgrade (no separate download needed), with no observable effects.

I sure wish this thing had a decent scheme to get the date/time from somewhere.  Even a reboot (required by the firmware upgrade), resets the clock.  I may try my hand at a script, but without setting the clock on each boot, the log timestamps are completely useless.  Not to mention that the log appears to be cleared on each boot.  Ugh.  I think there's a way to send the log transactions to a server, and that will be useful ...

Gotta go, be back this evening ...
