Hi Sylvia, I'm on vista and I go through periods of being booted off the internet. Not sure what it is: weather, atmosphere? If it gets really problematic I reboot the hub and it seems to clear. Strangely, Will hardly ever gets his connection broken, but he is upstairs and I'm quite a distance from the hub. I wonder if distance plays a part in it?
Hope you get back online on your main set up soon
