The following is an excellent answer to a question I didn't ask.

A good answer but an answer to the question - - - - how do I install a
dns server
on my system.

My question was and still is - - if I'm getting dns resolution on my router
how and/or what do I change so that I can now access the internet from
my computer.

What I've been able to find " $ service connman restart " dunno if that
will fix things.
