Thanks for the tips on the Netflix and the phones. I have actually advised hubs and dearest daughter NOT to let their phones update at all from the wifi. They can do that at school and work, lol.. Unfortunately, we have other options but none of them are land based. As for the Microsoft games, since I've posted my laptop had installed a Microsoft update overnight and this fixed the problem with them loading, we don't have an xbox, just have to use the log in for the games. I'm very weird about my computers and the amount of items I have on startup and running in the background, so I feel pretty confident that I've minimized any potential unwanted programs sucking the data that way.
Thanks again for the input. Anything else, please let me know.
