Just an update note...it was the router. Bought a new one that was a version up from the one I had and it installed well with no problems and all is back to operationg as usual. I had the other one for two years and two months...warranty was only good for a year. Nothing electronic last more than a few years anymore. I've got some Harmon-Kardon equipment I bought in 1983 that still gives service!! Try that today.
