I then rebooted the modem, router and then the S3s and they started hashing.
Is the desktop using the same DNS servers as the S3s?
I think the answer to that question is yes but Im unsure now that you ask. Is there a reason they would be different?
Time Warner Cable Internet was down this AM and spotty coming up... do you have TWC?
Yes I am with TWC . This explains what started the problem but not why I couldn't get them back up without the modem and router reboot while all other devices were connected.
