Only Rude Neighbors Hack Into Neighbor's WiFi
Don't Be on the Receiving End
better understand how to protect yourself from people who
may compromise your wireless network we need to learn what
they do in order to get inside. To protect yourself from a
breach you must think like a hacker. Chances are slim but
the intruder may not be your first door neighbor at all. A
hacker with a powerful high gain WiFi antenna could be sitting
hundreds of meters away and siphoning off your internet connection.
basic things can happen:
An intruder can log into your network and use the Internet
2. An intruder can log into your wireless access point (AP)

you decide to do that use WPA instead of WEP. It is a newer
and more secure standard. The way you actually implement the
security will depend on your wireless router and your computer's
operating system (Windows Vista, XP, Mac, Etc.) The documentation
you received with the router will describe the whole process
in detail. A strong password will deny hackers the opportunity
to log into your network, use the Internet and make changes
to your setup.
