This has not been addressed: What goes on w/ the router that unplug/plug seems to magically produce a connectable signal where moments before it was not?????

With electronics anything is possible, and a full reset can temporarily heal a lot of ills. Borrow or buy another router and see how it plays. They are not that expensive, and you could always return it if the problem continues.
