I recently found out that XP will create it's own wireless network if it doesn't find one to connect to. That means if there are other chasers around you even if they aren't connected to a true internet connection they will appear as a network option. Their computers can attempt to connect to you and you can attempt to connect to them computer to computer. This is actually a microsoft security vulnerability which is how I found it. Webstar is a brand of cable modem, perhaps they make wireless routers that some have converted to wifi scanners? Not sure there. Do you have a webstar anything?
