WPA can be cracked in a matter of hours if the router is has wifi protected setup enabled. This vulnerability was released December 2011. The tool used is called Reaver. I'm a penetration tester who uses it frequently. A lot of routers will not let you disable WPS either.

That’s a great point. I did not think about how the wallpaper can make your wireless network better by filtering out interference from other networks but it is still a more inconvenient option then just say securing your network. Besides a WPA key is very hard to crack and takes a long time to do so. I was talking about the average person and how they wouldn’t need the wallpaper to secure their networks. WPA should be enough.

The wallpaper cuts down on interference. So if your neighbor down the hall has a microwave that jams your wifi signal every night, this will help. Or if your apartment complex is just swamped with tons of wifi noise, this will improve your reception inside your own rooms. Also it’s not impossible to crack WPA keys, it’s just pretty hard. So if you’re paying to put in wallpaper anyway, why not add security from drive-by hackers for free?
