Home wireless (or "Wi-Fi") networks have become a popular way to connect to the Internet—but along with the convenience of a wireless network comes the need to have good Wi-Fi security in place. Almost all wireless routers—the devices that connect to the Internet and make access available wirelessly—have Wi-Fi encryption, which converts transmissions over your network into a code to prevent unauthorized access. Taking a close look at encryption requires a brief dip into techno-jargon. There are two kinds of encryption:

  • Wi-Fi Protected Access (commonly known as WPA)
  • Wired Equivalent Privacy (WEP)

Without going into detail about the differences, what you need to know about these two options is this: WPA is stronger, and you should use it if you have a choice.All the computers and other devices connected to your network must use the same kind of encryption. But once an encrypted system is up and running, it should operate transparently for authorized users, meaning once you've signed in with the system, you don't have to re-register every time you go online.
