I am just finishing up with updating to 4.10.3 if that matters.
Somewhere before that, the display of my network activity quit working.
   I think that it might have been exactly when my Ethernet ports were
assigned new and strange names.  I now have two named:

	enp5s12 enp0s18

Umm... you can thank systemd's udev for that.  (Whether Lennart actually
had anything to do with it or not I'm not sure, but it does feel like the
sort of stuff he tends to do.)

They apparently "decided" that the traditional/default-kernel style eth*
and wlan* interface names weren't confusing enough, and that names that
looked like some sort of ascii-armored encryption were far more useful.

The official explanation is that the new names are more stable or at
least predictable, which they arguably could be for people who have
several such interfaces and keep swapping them out.  What they apparently
forgot is the vast numbers of people who only have a single ethernet
interface and/or a single wlan interface, who are unlikely to ever change
it unless it breaks and they replace it, in which case the names stayed
the same before (eth0, wlan0), but are now likely to change.

As several of those first-page google hits should point out, the names
above stand for en=ethernet, p#=pci-bus-number, s#=slot-number.

And at least it's relatively easy to either disable the new naming and go
back to the old naming, or assign your own stable names as desired:

Something like this as /etc/udev/rules.d/70-persistent-net.rules should
assign your chosen name (as one line):

I didn't notice this, and this may be the problem. I don't have a file: "70-persistent-net.rules". I forget what was supposed to write it. I thought that it was written on boot if it didn't exist.
