4.Stream Movies to Any TV in the House

Instead of having a giant collection of DVDs or ripping your movies to every XBMC box you
have in your house, you can build yourself an affordable home media server and stream video
over Wi-Fi to any other HTPC (or Xbox or Playstation)-enabled TV in the house. Whether you
use Windows Media Center, XBMC, or something as simple as a Google Media Server Widget
for Windows, the possibilities are nearly endless—you can use any number of operating systems,
applications, and protocols to get your movies wirelessly from one computer to another.

B.6 Wi-Fi Security

Without any security enabled, Ethernet is more secure; however, the difference becomes
negligible when an Wi-Fi network is properly secured. Any device that connects to an Ethernet
network needs to be physically connected to the network. Since Wi-Fi devices can connect
anywhere within range of the wireless access point, the standard is more difficult to secure than
an Ethernet-based network. However, Wi-Fi networks can be adequately protected by enabling
password protection and data encryption.

Various wireless security protocols were developed to protect home wireless networks. These
wireless security protocols include WEP, WPA, and WPA2, each with their own strengths and
weaknesses. In addition to preventing uninvited guests from connecting to your wireless
network, wireless security protocols encrypt your private data as it is being transmitted over the
airwaves.

Wireless networks are inherently insecure. In the early days of wireless networking,
manufacturers tried to make it as easy as possible for end users. The out-of-the-box configuration
