I want to thank everybody for their suggestions. I still don't know what
the problem was but solved it by booting up the stretch installation /
rescue disk. Going through the initial setup, including the network
setup, cleared the problem.
A search of the web found reference to multiple cases of the same
problem. They all have one thing in common. Tons of replies with no
results. It seems that the first thing to try with this one is the
rescue disk. Something gets tweeked somewhere and the rescue disk
straightens it out. A puzzlement.

Hi all;
I am not 100% sure that the lan problem is connected to the memory
upgrade but the problem started right after I did the upgrade.
Setup:
Debian stretch
kde desktop
dp55kg motherboard
Increased ram from 4GB to 12GB Kingston sticks
I have run a complete memory test. All memory seems to be good.
On reboot, my router connection light is lit until the bios is
finished and the OS starts to load. At this point the light goes out.
I thought at first I has a cable problem but have found this not to be
the case. I have managed ( not sure how) to restore receiving but not
sending capability. Ping to localhost works. Ping to the router
doesn't. I have looked at all of the log files and have not been able
to spot anything pertinent. I tried restoring part of the system from
backup but that didn't work. The backup may be corrupted as well. All
of the files seem to be ok but I am not completely sure.
Has anyone had a similar problem and can suggest a fix. I will supply
added information as needed.
