Airport utility an error occurred while updating the configuration
So, Apple seems to be releasing incremental updates to add those features back to the re-engineered software as the rewrites are completed.
The Airport Utility really has been getting better and better with time. Certainly, this latest Airport firmware update is another story.
It is possible that devices connected with the CAT 5 cables were the problem (rather than those connected with CAT 5E or CAT 6 cables), but at best, this notion is unproven conjecture on my part.
After days of trouble-shooting and tediously plugging and unplugging Ethernet cables and powering off-and-on every network device numerous times I was at my wits end. I decided to try this one last solution and downgraded the firmware. So far today, I've had a stable, reliable and fast Ethernet-based Internet connection all day.
Subsequent runs of Airport Utility report no firmware update required, and indicate a current version. I've also had occasional update issues with other things through the Apple App store and i Tunes, but they've never appeared to produce functional issues.
However, during this software re-write, the revised software still does not include several settings tools that once were available in older versions.
I began wading through a list of lengthy troubleshooting steps to try and isolate the cause, nearly a week removed from the two Apple software updates.
I installed the Netgear GS724Tv3 (also called GS724T-300NAS), but the network still did not work.

After upgrading to this software, our Ethernet backbone (with four Netgear Pro Safe switches linked with a mix of CAT 5, 5E and 6 RJ-45 cable) died.
