Hi
Well wire for sure would solve the problem.
However, Wireless is So “cool”

that it might be worth to invest a little
more effort to try.
Open the Wireless Configuration (WZC) choose to connect to Preferred
Networks and remove all the Networks that are Not yours from the list. Every
time you click on a foreign Network it would be entered into the preferred
list, so, if someone Clicks on another Wireless Network remove it again fro
the list.
If it does not work try to load the original Wireless utility that came with
the Wireless Card, some of this utilities have the capacity to restrict
connection to one particular Wireless Network.
In order to try the utility you would need to disable WZC.
Here how the Disable/Enable WZC,
