I have a wireless setup in my home as well, and have setup WEP (wireless encrytion protocol) to have a "key" (a multi-digit combination Hex and Alphanumeric number) that I chose, and must be entered, before the router will allow any connection to our network. I also do not "broadcast" my SSID, so others in the neighborhood can't "see" my network. I also can see several of my neighbors wireless networks as well, but refrain from connecting to theirs for the same reason I don't want anyone sharing mine. I have shared systems in the house, so that we can all access each others systems through explorer, as well as shared printers, so that anyone can use the color printer, along with the b/w laser... I'd highly suggest you figure out how to setup WEP, its really easy, and will prevent unauthorized access to your network. So you can sleep at night... steve
