I just ran netstat -rn on the FreeBSD tower I'm running now and the
default address is identical.  I checked the ISP's webpage for the
modem that that's the address it uses as well.

I tinkered with the laptop this past weekend and I found the following:

- the machine won't connect with the modem when even when running a
liveCD version of FreeBSD (both 10 and 11)--all attempts to ping a URL
failed
- the machine updates the file:

 /var/db/dhclient.leases.nfe0

but it doesn't add anything
- as a test, I created a backup of that file, deleted the original,
and found that the machine will still create and write to it, but
doesn't add anything
- the last update of that file roughly corresponds to the time and
date when I connected that modem

A while ago, I installed FreeBSD 10.x on an old IBM ThinkPad and I was
successfully send pings to the same URL as before.

This is becoming interesting....
