I am having the same issue, however when I replaced my old computer with a new desktop running Windows 7, it made the network wonky for every device in our home that is connected to it! Various computers and devices (Kindle, iPad, Roku) randomly go offline and the only way to get them back on is to reboot the router, even though other devices ARE connected to the network. Does anyone have any advice for me?
