These are all tied in somehow. I searched high and low and this problem is extremely common, built right into Windows 7 as far back as 2009... yet nobody has EVER pinpointed it. Is there a place to submit unsolved Windows 7 glitches? I've frankly given up on it. I refuse to deal with it anymore. I've long ago realized that only XP must be at the center of my home media network.
Which is why I concluded it is most likely a router problem. One thing for certain is that millions of people using Windows 7 have never had this problem at all including me.

In either event a reinstallation should fix the problem if it's related to Windows 7. Carefully checking the streaming functions as third party programs are installed might help narrow it down.
