Hurray! I got it working. The old unit definitely had a problem. It took 5 times as long just to start. I'm sending the old unit back under RMA tomorrow. However, another factor that has to be changed for Linksys routers, I found out, is that you have to disable "Block Anonymous Internet Requests" in security. I researched the setting and you really don't compromise your security by doing this. Supposedly, your router will now respond to pings, but several security dudes said absolute silence is no better. Your overall security perimeter is not compromised. Worth it, IMHO, to get video.
The actual unit works great (now that it is working)!
Thanks to you all for helping.
