A quick note to close the book on this post.
Jaquith's post jogged my memory regarding WIFI so I called my buddy in CA and asked him to describe his connection to the internet; result, he uses a broadband router provided by his cable company that allows wireless connections. In asking a few more questions I determined that he had replaced everything BUT the transformer for the router. Once the transformer was replaced everything started working again. The old transformer was putting out just enough juice to light the panel LED's but not enough to drive the unit.
Bottom line, the MOBO was fine, we are idiots!
My thanks to jaquith for giving my memory a swift kick, I have selected his last post as "Best Answer"
