It is possible that someone is hijacking your network ( using your wireless
bandwidth ). What kind of security do you have set up on your wireless
network? Many Access Points allow you to only allow certain MAC addresses
onto the network. This is a small piece of the security you should have
enabled. Other items are 802.1x security, WEP keys, and WPA. Look into
what your Access Point supports by going to their web site or read the
manual. You should lock down the AP as much as possible, and set your
wireless devices to only talk with the AP.
