WiFi signals run across the same frequency as several other products, like microwave ovens (that means your microwave oven has enough radiation leakage to interfere with WiFi, and more than is likely exceeds what is allowed by law), cordless phones that are in the 2.4Ghz frequency (5.8ghz is better anyway) and baby monitors. The waves are absorbed, blocked and weakened by things like metal (as in the wire mesh in stucco walls and metal film coated windows), objects with a lot of water (like humans, distance, stone or brick (including "transparent stone" - glass), and objects that cause their radiated signals to deflect and bend. But, for folks that need a signal in places where Cat5e is not practical, it can be a good solution.
Krystine, re: concerns for signals getting intercepted, using WPA or WPA2 security protocols (all modern WiFi units have that) will certainly lock down the signals to the point where you would have nothing to worry about, as long as you use a good, strong Passphrase with a value that would be difficult to guess. The older WEP security is not as strong, and is fairly easy to crack. In addition to WPA/WPA2 (or even WEP) you can also use MAC filtering to allow only certain MAC addresses on specific machines to connect to your WiFi Router/Access Point. I do not have a How To document that is WiFi specific, but I do cover this kind of WiFi info, and more, with my little old "Bullet-Proof Your Computer, Protect Your Data" document. You can connect to my ftp anonymously (non-passive connection) at ftp://gilhale.dnsalias.com/_Bullet-ProofYourData to download a copy. Ciao!
