Here are the two commands that I am using...

I should make it perfectly clear:  I really have very little idea
WHAT these commands are really doing or why some other commands should
or should not be included.  As I indicated:  I COPIED what was posted
here a while back.  And, while it is not 100% because it does not
change the DHCPMON so it looks at the WiFi, it DOES switch the
connectivity.  That is the important factor from my perspective.  And,
when I use the ActENet.Cmd after I've reconnected to the wired
connection, DHCPMON picks back up and recognizes that the lease for
that connection is back.  It just never shows the lease for the
WiFi connection... :-(

BUT, even with the above commands, that kill the DHCPSTRT for LAN0 and
restarts it for LAN1, the DHCPMON insists on monitoring *only* LAN0.

I did try adding a command in the Cmd files above to try to switch the
monitor:

	'@ start dhcpmon -LANn'   with n=0 or n=1

But, it made no difference whatsoever.  

Later...
