Setting up a home router is honestly not difficult to do if you follow the instruction booklet. (I have a Linksys.) Most routers (definitely Linksys) come with abilities to secure your own network. You can SEE all the wireless networks in the area but can only hook into one if it's unsecured (which it will tell you) or if you're a hacker! I really don't know what the point of Network Magic would be -- on one hand if there IS a hacker it could be good to know but I doubt you would be able to identify the source. One piece of advice though that I do have in setting up a network is to NOT name it something that can be immediately identifiable to someone who doesn't know you. No addresses and I wouldn't even suggest using a last name -- aside from cyber-invasion, this way if someone does see something that might be in your home as tantalizing by virtue of hacking in, they wouldn't know which home to go to!! (Or know when you were or weren't home.)
