Anti-WiFi Wallpaper Available Next Year 167
hypnosec writes with good news for folks who want to live in a Faraday cage. From the article: "A new type of wallpaper, which has been developed by scientists from the Institut Polytechnique Grenoble INP and the Centre Technique du Papier, will go on sale in 2013 after a Finnish firm Ahlstrom acquired the license. What looks like a bog-standard wallpaper roll actually contains silver particles that allows it to filter out up to three different frequencies simultaneously. It is not the first time that such a technology has surfaced. Back in 2004, BAE Systems was tasked by Ofcom to come up with a similar solution based on what was then called a stealth wallpaper. It used copper instead of silver and blocked Wi-Fi signals while letting GSM, 4G and emergency calls through. Back then, though, a square meter cost £500, whereas the Wi-Fi wallpaper devised by the French researchers should be priced reasonably, with costs matching those of a 'classic,' mid-range wallpaper according to M. Lemaître-Auger, from Grenoble INP."

Paint your wall with magnetic paint, wallpaper over it.

Paint your walls with two coats of this primer, and paint into the electrical boxes to where you can ground it. I used under wallpaper speaker wire that is just a stick thin copper foil, I ran a 3" strip out the electrical box connected to the ground, painted over it.
Wifi and cellular coverage in that room is completely lost when the door is closed (which is also painted) and I have aluminum storm windows and aluminum screens on the windows.
Made a huge difference to RF interference to my ham shack. the number of "birdies" from crap in the home went down to nothing so I could pull in signals that were closer to the noise floor a lot easier.

what you really need is two layers the outside layer an antenna to pick up the neighbours wifi and this on the inside to keep them from picking up yours.
