i have a laptop connected to the desktop with a wireless router, linksys. the last few days i clicked to look at the connections and it tells me to choose one. i have the one that is supposed to be there and one called angel today. so what are these extra nets, joe d and angel? also i have a firewall on from microsoft but the list says my net connection is unsecured. what's up with that. win xp on both desk and lap.
