That's because you are on "their network" along with everyone else. At home, it's "your" network, so only the people within your airport range that know the name and password of the network can get on it, then they would need the name and password of your computer to get on that.<br><br>I'm not saying you're totally safe, cause they can still get in if they have your IP address, but the security is much better at home than an open network at school.<br><br>
