I just learned that a problem I have been having, literally, for a couple of years is due to the nameserver. I solved the problem by changing the nameserver, in /etc/resolv.conf to nameserver 8.8.8.8 (google) I think this is a temporary solution. I then started to study on this and found that there seems to be, again literally, hundreds of solutions. So, this is to request which solution is best for 18.04 so I can fix my systems so that my network no longer hangs forever whilst telling me everything is dandy.
Thank you...............
