I was able to connect the TV to the wireless network. The problem was with the router itself. Since you give advice to folks, here's what the problem was, that you may share with others.
My router is a Cisco Linksys E1000 which when it is set up establishes a "Guest" SSID that is the same name as the main SSID but with the suffix "-guest". This is the SSID that one is suppose to use to connect external devices to the network.
However, that was not working at all. The "SSID-guest" was found during the TV Scans of the networks, but the TV never noted it as needing a password (Security Key), so it went nowhere.
When I attempted to connect to the main SSID, the TV recognized it as needing a Security Key, asked me to enter it, and everything connected.
So thanks again for your help and thanks for the full User's Guide as well.
Have a Great Christmas!!!
