Actually there seem to be two related or unrelated issues. One seems to be
purely DNS and the other Network Manager... Dunno. My original issue was
Network Manager. Now ok for no reason i can see. The more sticky one with
my latest upgrade was no problem linking to my WiFi but no internet when
linked. Using Google's 8.8.8.8 address in IPV4 solved that, which seemed to
be caused by resolvconf solutions or workarounds have been posted but turn
out to be temporary fixes that then become unfixed again ... On reboot...
And sometimes even without reboot.
Ho ... Hum...
