OK I brought the new computer home today and was finishing the set up and when I went to connect it to the wifi I note that there is a wifi connection called "Hidden connection" and it is password protected. I am on lots of acreage in the woods, and the nearest house is probably 3-500 yards away. I checked with everyone in our house, no one knows about hidden network. Any ideas? I have a fair-sized linksys wifi with four or six of those aerials sticking up in back. What does this mean? is there someone on my wifi?...
