Well, when I uninstalled and reinstalled, in order to get the (i) icon back, the first update took 15:04.
What I did this time was watch the router to see when the data was being exchanged and what the hard drive did.
It appears that after the update files are downloaded and received, the software is updating the files almost immediately, which is what I believe should be happening. Then we have that gap of several minutes when the hard drive shows no activity. Then, the hard drive shows activity and the audio with visual indication of the update, appears afterwards. This gap of several minutes, eludes me, since there is nothing in the log to indicate that anything is happening aside from updating the software with the new file, but there was no hard drive activity...
Anyhow, it is working, so I'm leaving it as it is.
