If you have an old house with stucco exterior walls the substrate used to hold the stucco on can be a metal mesh which can have a mesh fine enough to attenuate a wifi signal quite well. -- I am quite sure now that often, very often, in matters concerning religion and politics a man's reasoning powers are not above the monkey's. - Mark Twain in Eruption
Heh, my (not living in it right now) house built less than 15 years ago has stucco/lath on the outside. And a tin roof up top! Inside walls aren't too meaty though so inside WiFi coverage is no big deal.
